===Design Rationale===
'''Build Pictures - [https://drive.google.com/drive/u/0/#folders/0B6jW74m222OmMTJlX2VvX01vTEU]'''
#The Rotor blade design, which is attached to the shaft in the middle of hopper, and attached to the outer diameter of rotor sweep on the outer edges of hopper - allows for a '''complete sweep of the hopper''' - no soil buildup in corners of cylindrical hopper
#Anti-symmetric rotor blade design allows for soil sweeping into the middle - as soil from the far ends of the hopper is moved towards the middle.
#Reinforcement in middle of rotor blade to strengthen the rather thin blade.
#Hopper reinforcement gussets on outside of hopper are not evenly spaced with the outer edges but instead slighly closer to the center of the machine - because - the only reason those gussets are placed where they are is so that they surround the opening at the bottom of the hopper. The entire hopper is made out of 1/8" material. The only thing that is 1/2" is the base plate, which I think is the exact same base plate as on previous builds. I may have to add some reinforcement around the rim, we'll see.
#Tines are or are not twisted or bent? - Those tines are actually flat and they are just welded at off angles. It took me a while to get them adjusted so they don't rub on the hopper, but I haven't tried them with soil yet.
#How do you bend the hopper into shape? - I was actually able to form the large hopper part over the edge of a table. I had them cut slits in it, per the cut file, so that it actually forms into the multi-sided shape that you see in the model, so it is not exactly a smooth curve. Then I went back and welded the slits so it would be more solid. Then the gussets constrain it's final shape. I think I'll add some tongue and slot to the model of this hopper, because I found out, after the fact, that that would have helped.
#Geardown to slow down the auger spin speed - what are the details of geardown and spin speed? -That is something that I'm interested to see. The specs on the 7cu-in motor that I found at the shop says that the motor can get down to 65rpm. Since the sprockets are 10tooth and 60tooth, I might be able to turn the mixer as low as 11rpm. I may have the motor hooked up and running in the next two weeks, so we'll see what happens.

Do the tines need bending and/or twisting, or are they flat?

===Design Review===
'''Outside Review'''

Anecdotal evidence says that [[AECT]] had an auger in their big hopper, but it was removed because it didn't work. And that Powell and Sons may also have a hopper.

1. "Augert will suck all the juice out of your hydraulics" - I don't think that is an issue with proper control timing. We have excess hydraulic flow during the motion of the secondary cylinder - which can be used to move soil.

2. "Requires larger hopper when in fact soil just needs to flow smoothly in the hopper" - Our goal is to help move the soil, as we know that soil does not always want to move smoothly.

3. "Soil should be mixed properly BEFORE it goes in the hopper." - This is true in all cases.

4. "The conveyor really helps us get a uniform (no stones no clods) soil mix into the reduced hopper--and we only turn it on to load dirt for 50 blocks and so it takes no hydraulics away from pressing." - I guess Dan discovered free energy on this one:)

'''Marcin:'''

Dan did a conveyor:

http://propagelleprojects.blogspot.com/2014/06/the-conveyor-unveiled-and-on-site.html

Before than, an auger in hopper- http://propagelleprojects.blogspot.com/2014/02/auger-added-to-ceb-brick-machine.html

And mini tines in hopper - http://propagelleprojects.blogspot.com/2013/04/test-blocks.html

'''Rob:'''

Thanks, this is good info. I've read a few of Dan's blogs but I want to go back and take a look at more. I have thought about a lot of these things, and that is correct I will probably have to make sure that I'm not compressing and mixing at the same time. I may even end up doing some kind of conveyor like this to use either after the mixer or to feed the mixer. The design of this mixer may make it a little difficult for my tractor to load it while it is mounted to the machine, since my loader is small. The diameter of the blades on this mixer should be 24in, if I remember correctly. I'm figuring on only loading the mixer about half way, but I'm not sure what it will be capable off. Just to keep the soil from bridging the auger may not have to be big at all, even closer to 10in diameter.

Just for future reference, I've seen some hoppers at asphalt plants that have conveyors under them. Sometimes, what they do on these large hoppers to keep them from bridging is that they have a "dancer" plate. The dancer plate is just one wall of the hopper that is hinged and is actuated to move in and out/oscillate.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

I have thought about a lot of these things, and that is correct I will probably have to make sure that I'm not compressing and mixing at the same time. I may even end up doing some kind of conveyor like this to use either after the mixer or to feed the mixer. The design of this mixer may make it a little difficult for my tractor to load it while it is mounted to the machine, since my loader is small. The diameter of the blades on this mixer should be 24in, if I remember correctly. I'm figuring on only loading the mixer about half way, but I'm not sure what it will be capable off. Just to keep the soil from bridging the auger may not have to be big at all, even closer to 10in diameter.

Just for future reference, I've seen some hoppers at asphalt plants that have conveyors under them. Sometimes, what they do on these large hoppers to keep them from bridging is that they have a "dancer" plate. The dancer plate is just one wall of the hopper that is hinged and is actuated to move in and out/oscillate.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

-using snap acting/limit switch [http://www.mcmaster.com/#7090k37/=13yikgx] mounted with magnets from local home store for stopping the travel of the main cylinder drop, now the only thing that I'm using the pressure switch for is the compression step. Getting very consistent block heights with this method.

-added a few mixing paddles to get a more consistent mix, picture will come later

=January 10, 2016=

-Tried a grate at the bottom of the mixer/hopper with about 1" between bars. Works, and keeps out rocks, but gets clogged too much.

-have to be careful putting in cement, because if you put all of the cement on one side of the hopper it doesn't mix with both sides.

==With Mixer Module==
===Differences===
Outside of different hopper design - the other differences are: The only difference in the frame of the mixer version is that there is one extra hole in the primary arms, and one of the guards has some extra cutouts. The hopper support tubes are also slightly different.

-THIS IS THE STEP FILE THE CURRENT DESIGN FOR THE PRESS WITH THE MIXER MODULE CURRENTLY UNDERGOING TEST.

'''Download STEP file for FreeCAD - [[FILE:01-001-01-6 MIXER MODULE 11-2-14.STP]]''':

'''Download FreeCAD file - [[File:CEB_Mixer.fcstd]]'''

[[Image:CEB2014auger.png|300px]]

===Design Rationale===
'''Build Pictures - [https://drive.google.com/drive/u/0/#folders/0B6jW74m222OmMTJlX2VvX01vTEU]'''
#The Rotor blade design, which is attached to the shaft in the middle of hopper, and attached to the outer diameter of rotor sweep on the outer edges of hopper - allows for a '''complete sweep of the hopper''' - no soil buildup in corners of cylindrical hopper
#Anti-symmetric rotor blade design allows for soil sweeping into the middle - as soil from the far ends of the hopper is moved towards the middle.
#Reinforcement in middle of rotor blade to strengthen the rather thin blade.
#Hopper reinforcement gussets on outside of hopper are not evenly spaced with the outer edges but instead slighly closer to the center of the machine - because - the only reason those gussets are placed where they are is so that they surround the opening at the bottom of the hopper. The entire hopper is made out of 1/8" material. The only thing that is 1/2" is the base plate, which I think is the exact same base plate as on previous builds. I may have to add some reinforcement around the rim, we'll see.
#Tines are or are not twisted or bent? - Those tines are actually flat and they are just welded at off angles. It took me a while to get them adjusted so they don't rub on the hopper, but I haven't tried them with soil yet.
#How do you bend the hopper into shape? - I was actually able to form the large hopper part over the edge of a table. I had them cut slits in it, per the cut file, so that it actually forms into the multi-sided shape that you see in the model, so it is not exactly a smooth curve. Then I went back and welded the slits so it would be more solid. Then the gussets constrain it's final shape. I think I'll add some tongue and slot to the model of this hopper, because I found out, after the fact, that that would have helped.
#Geardown to slow down the auger spin speed - what are the details of geardown and spin speed? -That is something that I'm interested to see. The specs on the 7cu-in motor that I found at the shop says that the motor can get down to 65rpm. Since the sprockets are 10tooth and 60tooth, I might be able to turn the mixer as low as 11rpm. I may have the motor hooked up and running in the next two weeks, so we'll see what happens.

Do the tines need bending and/or twisting, or are they flat?

[[Image:CEB2014auger_tines.png|300px]]

Inner gussets towards centerline of machine instead of evenly spaced from edges of hopper because they are thinner (1/8") than edge (1/4"):

[[Image:CEB2014auger_gussets.png|300px]]

Geardown of auger - 5x or so:

[[Image:CEB2014auger_geardown.png|300px]]

===Design Review===
'''Outside Review'''

Anecdotal evidence says that [[AECT]] had an auger in their big hopper, but it was removed because it didn't work. And that Powell and Sons may also have a hopper.

1. "Augert will suck all the juice out of your hydraulics" - I don't think that is an issue with proper control timing. We have excess hydraulic flow during the motion of the secondary cylinder - which can be used to move soil.

2. "Requires larger hopper when in fact soil just needs to flow smoothly in the hopper" - Our goal is to help move the soil, as we know that soil does not always want to move smoothly.

3. "Soil should be mixed properly BEFORE it goes in the hopper." - This is true in all cases.

4. "The conveyor really helps us get a uniform (no stones no clods) soil mix into the reduced hopper--and we only turn it on to load dirt for 50 blocks and so it takes no hydraulics away from pressing." - I guess Dan discovered free energy on this one:)

'''Marcin:'''

Dan did a conveyor:

Before than, an auger in hopper- http://propagelleprojects.blogspot.com/2014/02/auger-added-to-ceb-brick-machine.html

And mini tines in hopper - http://propagelleprojects.blogspot.com/2013/04/test-blocks.html

-using snap acting/limit switch [http://www.mcmaster.com/#7090k37/=13yikgx] mounted with magnets from local home store for stopping the travel of the main cylinder drop, now the only thing that I'm using the pressure switch for is the compression step. Getting very consistent block heights with this method.

[[Image:CEB2014.png|300px]]

==With Mixer Module==
===Differences===
Outside of different hopper design - the other differences are: The only difference in the frame of the mixer version is that there is one extra hole in the primary arms, and one of the guards has some extra cutouts. The hopper support tubes are also slightly different.

-THIS IS THE STEP FILE THE CURRENT DESIGN FOR THE PRESS WITH THE MIXER MODULE CURRENTLY UNDERGOING TEST.

'''Download STEP file for FreeCAD - [[FILE:01-001-01-6 MIXER MODULE 11-2-14.STP]]''':

'''Download FreeCAD file - [[File:CEB_Mixer.fcstd]]'''

[[Image:CEB2014auger.png|300px]]

===Design Rationale===
'''Build Pictures - [https://drive.google.com/drive/u/0/#folders/0B6jW74m222OmMTJlX2VvX01vTEU]'''
#The Rotor blade design, which is attached to the shaft in the middle of hopper, and attached to the outer diameter of rotor sweep on the outer edges of hopper - allows for a '''complete sweep of the hopper''' - no soil buildup in corners of cylindrical hopper
#Anti-symmetric rotor blade design allows for soil sweeping into the middle - as soil from the far ends of the hopper is moved towards the middle.
#Reinforcement in middle of rotor blade to strengthen the rather thin blade.
#Hopper reinforcement gussets on outside of hopper are not evenly spaced with the outer edges but instead slighly closer to the center of the machine - because - the only reason those gussets are placed where they are is so that they surround the opening at the bottom of the hopper. The entire hopper is made out of 1/8" material. The only thing that is 1/2" is the base plate, which I think is the exact same base plate as on previous builds. I may have to add some reinforcement around the rim, we'll see.
#Tines are or are not twisted or bent? - Those tines are actually flat and they are just welded at off angles. It took me a while to get them adjusted so they don't rub on the hopper, but I haven't tried them with soil yet.
#How do you bend the hopper into shape? - I was actually able to form the large hopper part over the edge of a table. I had them cut slits in it, per the cut file, so that it actually forms into the multi-sided shape that you see in the model, so it is not exactly a smooth curve. Then I went back and welded the slits so it would be more solid. Then the gussets constrain it's final shape. I think I'll add some tongue and slot to the model of this hopper, because I found out, after the fact, that that would have helped.
#Geardown to slow down the auger spin speed - what are the details of geardown and spin speed? -That is something that I'm interested to see. The specs on the 7cu-in motor that I found at the shop says that the motor can get down to 65rpm. Since the sprockets are 10tooth and 60tooth, I might be able to turn the mixer as low as 11rpm. I may have the motor hooked up and running in the next two weeks, so we'll see what happens.

Do the tines need bending and/or twisting, or are they flat?

[[Image:CEB2014auger_tines.png|300px]]

Inner gussets towards centerline of machine instead of evenly spaced from edges of hopper because they are thinner (1/8") than edge (1/4"):

[[Image:CEB2014auger_gussets.png|300px]]

Geardown of auger - 5x or so:

[[Image:CEB2014auger_geardown.png|300px]]

===Design Review===
'''Outside Review'''

Anecdotal evidence says that [[AECT]] had an auger in their big hopper, but it was removed because it didn't work. And that Powell and Sons may also have a hopper.

1. "Augert will suck all the juice out of your hydraulics" - I don't think that is an issue with proper control timing. We have excess hydraulic flow during the motion of the secondary cylinder - which can be used to move soil.

2. "Requires larger hopper when in fact soil just needs to flow smoothly in the hopper" - Our goal is to help move the soil, as we know that soil does not always want to move smoothly.

3. "Soil should be mixed properly BEFORE it goes in the hopper." - This is true in all cases.

4. "The conveyor really helps us get a uniform (no stones no clods) soil mix into the reduced hopper--and we only turn it on to load dirt for 50 blocks and so it takes no hydraulics away from pressing." - I guess Dan discovered free energy on this one:)

'''Marcin:'''

Dan did a conveyor:

http://propagelleprojects.blogspot.com/2014/06/the-conveyor-unveiled-and-on-site.html

Before than, an auger in hopper- http://propagelleprojects.blogspot.com/2014/02/auger-added-to-ceb-brick-machine.html

And mini tines in hopper - http://propagelleprojects.blogspot.com/2013/04/test-blocks.html

'''Rob:'''

Thanks, this is good info. I've read a few of Dan's blogs but I want to go back and take a look at more. I have thought about a lot of these things, and that is correct I will probably have to make sure that I'm not compressing and mixing at the same time. I may even end up doing some kind of conveyor like this to use either after the mixer or to feed the mixer. The design of this mixer may make it a little difficult for my tractor to load it while it is mounted to the machine, since my loader is small. The diameter of the blades on this mixer should be 24in, if I remember correctly. I'm figuring on only loading the mixer about half way, but I'm not sure what it will be capable off. Just to keep the soil from bridging the auger may not have to be big at all, even closer to 10in diameter.

Just for future reference, I've seen some hoppers at asphalt plants that have conveyors under them. Sometimes, what they do on these large hoppers to keep them from bridging is that they have a "dancer" plate. The dancer plate is just one wall of the hopper that is hinged and is actuated to move in and out/oscillate.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

===Design Rationale===
'''Build Pictures - [https://drive.google.com/drive/u/0/#folders/0B6jW74m222OmMTJlX2VvX01vTEU]'''
#The Rotor blade design, which is attached to the shaft in the middle of hopper, and attached to the outer diameter of rotor sweep on the outer edges of hopper - allows for a '''complete sweep of the hopper''' - no soil buildup in corners of cylindrical hopper
#Anti-symmetric rotor blade design allows for soil sweeping into the middle - as soil from the far ends of the hopper is moved towards the middle.
#Reinforcement in middle of rotor blade to strengthen the rather thin blade.
#Hopper reinforcement gussets on outside of hopper are not evenly spaced with the outer edges but instead slighly closer to the center of the machine - because - the only reason those gussets are placed where they are is so that they surround the opening at the bottom of the hopper. The entire hopper is made out of 1/8" material. The only thing that is 1/2" is the base plate, which I think is the exact same base plate as on previous builds. I may have to add some reinforcement around the rim, we'll see.
#Tines are or are not twisted or bent? - Those tines are actually flat and they are just welded at off angles. It took me a while to get them adjusted so they don't rub on the hopper, but I haven't tried them with soil yet.
#How do you bend the hopper into shape? - I was actually able to form the large hopper part over the edge of a table. I had them cut slits in it, per the cut file, so that it actually forms into the multi-sided shape that you see in the model, so it is not exactly a smooth curve. Then I went back and welded the slits so it would be more solid. Then the gussets constrain it's final shape. I think I'll add some tongue and slot to the model of this hopper, because I found out, after the fact, that that would have helped.
#Geardown to slow down the auger spin speed - what are the details of geardown and spin speed? -That is something that I'm interested to see. The specs on the 7cu-in motor that I found at the shop says that the motor can get down to 65rpm. Since the sprockets are 10tooth and 60tooth, I might be able to turn the mixer as low as 11rpm. I may have the motor hooked up and running in the next two weeks, so we'll see what happens.

Do the tines need bending and/or twisting, or are they flat?

===Design Review===
'''Outside Review'''

Anecdotal evidence says that [[AECT]] had an auger in their big hopper, but it was removed because it didn't work. And that Powell and Sons may also have a hopper.

1. "Augert will suck all the juice out of your hydraulics" - I don't think that is an issue with proper control timing. We have excess hydraulic flow during the motion of the secondary cylinder - which can be used to move soil.

2. "Requires larger hopper when in fact soil just needs to flow smoothly in the hopper" - Our goal is to help move the soil, as we know that soil does not always want to move smoothly.

3. "Soil should be mixed properly BEFORE it goes in the hopper." - This is true in all cases.

4. "The conveyor really helps us get a uniform (no stones no clods) soil mix into the reduced hopper--and we only turn it on to load dirt for 50 blocks and so it takes no hydraulics away from pressing." - I guess Dan discovered free energy on this one:)

'''Rob:'''

Thanks, this is good info. I've read a few of Dan's blogs but I want to go back and take a look at more. I have thought about a lot of these things, and that is correct I will probably have to make sure that I'm not compressing and mixing at the same time. I may even end up doing some kind of conveyor like this to use either after the mixer or to feed the mixer. The design of this mixer may make it a little difficult for my tractor to load it while it is mounted to the machine, since my loader is small. The diameter of the blades on this mixer should be 24in, if I remember correctly. I'm figuring on only loading the mixer about half way, but I'm not sure what it will be capable off. Just to keep the soil from bridging the auger may not have to be big at all, even closer to 10in diameter.

Just for future reference, I've seen some hoppers at asphalt plants that have conveyors under them. Sometimes, what they do on these large hoppers to keep them from bridging is that they have a "dancer" plate. The dancer plate is just one wall of the hopper that is hinged and is actuated to move in and out/oscillate.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

==ceb main cylinder==

hey rob! just watched your youtube videos. awesome work. props for usuing a breadboard! lol.

saw where you were talking about adjusting the press foot. thought i'd suggest another idea. using four pieces of all thread to mount a seconardy foot above the plate attached to the cylinder.

[[Image:Ose-cebpress-idea-pressfoot.png|100px]]

or

do you think it could also work to put an adjustable limit switch somewhere on it?

party on
--[[User:Dorkmo|Dorkmo]] ([[User talk:Dorkmo|talk]]) 04:26, 9 January 2016 (CET)

I like the four bolt idea because that might allow you to adjust that foot front, back, left, and right. That's something to think about.

-Code that I'm working on that uses the Arduino Micro for the CEB Press with mixer module, based on original code by several others ((see [[CEB_Press_6_-_Controller_Module_-_3D_CAD]]) (WKJCEB.ino)

-The hydraulic motor on the mixer causes some pressure spikes, this necessitates some extra delays, de-bouncing, etc.)

==CEB Press==
*THIS IS THE STEP FILE FOR THE CURRENT HOPPER PRESS THAT I HAVE. THIS MAY BE THE SAME STEP FILE AS THE OFFICIAL ONE LISTED ON THE DEV. PAGE.
*'''Updated 4/3/15 - latest file - [[File:01-001-00-6.stp]]''':

[[Image:CEB2014.png|300px]]

==With Mixer Module==
===Differences===
Outside of different hopper design - the other differences are: The only difference in the frame of the mixer version is that there is one extra hole in the primary arms, and one of the guards has some extra cutouts. The hopper support tubes are also slightly different.

-THIS IS THE STEP FILE THE CURRENT DESIGN FOR THE PRESS WITH THE MIXER MODULE CURRENTLY UNDERGOING TEST.

'''Download STEP file for FreeCAD - [[FILE:01-001-01-6 MIXER MODULE 11-2-14.STP]]''':

'''Download FreeCAD file - [[File:CEB_Mixer.fcstd]]'''

[[Image:CEB2014auger.png|300px]]

===Design Rationale===
'''Build Pictures - [https://drive.google.com/drive/u/0/#folders/0B6jW74m222OmMTJlX2VvX01vTEU]'''
#The Rotor blade design, which is attached to the shaft in the middle of hopper, and attached to the outer diameter of rotor sweep on the outer edges of hopper - allows for a '''complete sweep of the hopper''' - no soil buildup in corners of cylindrical hopper
#Anti-symmetric rotor blade design allows for soil sweeping into the middle - as soil from the far ends of the hopper is moved towards the middle.
#Reinforcement in middle of rotor blade to strengthen the rather thin blade.
#Hopper reinforcement gussets on outside of hopper are not evenly spaced with the outer edges but instead slighly closer to the center of the machine - because - the only reason those gussets are placed where they are is so that they surround the opening at the bottom of the hopper. The entire hopper is made out of 1/8" material. The only thing that is 1/2" is the base plate, which I think is the exact same base plate as on previous builds. I may have to add some reinforcement around the rim, we'll see.
#Tines are or are not twisted or bent? - Those tines are actually flat and they are just welded at off angles. It took me a while to get them adjusted so they don't rub on the hopper, but I haven't tried them with soil yet.
#How do you bend the hopper into shape? - I was actually able to form the large hopper part over the edge of a table. I had them cut slits in it, per the cut file, so that it actually forms into the multi-sided shape that you see in the model, so it is not exactly a smooth curve. Then I went back and welded the slits so it would be more solid. Then the gussets constrain it's final shape. I think I'll add some tongue and slot to the model of this hopper, because I found out, after the fact, that that would have helped.
#Geardown to slow down the auger spin speed - what are the details of geardown and spin speed? -That is something that I'm interested to see. The specs on the 7cu-in motor that I found at the shop says that the motor can get down to 65rpm. Since the sprockets are 10tooth and 60tooth, I might be able to turn the mixer as low as 11rpm. I may have the motor hooked up and running in the next two weeks, so we'll see what happens.

Do the tines need bending and/or twisting, or are they flat?

[[Image:CEB2014auger_tines.png|300px]]

Inner gussets towards centerline of machine instead of evenly spaced from edges of hopper because they are thinner (1/8") than edge (1/4"):

[[Image:CEB2014auger_gussets.png|300px]]

Geardown of auger - 5x or so:

[[Image:CEB2014auger_geardown.png|300px]]

===Design Review===
'''Outside Review'''

Anecdotal evidence says that [[AECT]] had an auger in their big hopper, but it was removed because it didn't work. And that Powell and Sons may also have a hopper.

1. "Augert will suck all the juice out of your hydraulics" - I don't think that is an issue with proper control timing. We have excess hydraulic flow during the motion of the secondary cylinder - which can be used to move soil.

2. "Requires larger hopper when in fact soil just needs to flow smoothly in the hopper" - Our goal is to help move the soil, as we know that soil does not always want to move smoothly.

3. "Soil should be mixed properly BEFORE it goes in the hopper." - This is true in all cases.

4. "The conveyor really helps us get a uniform (no stones no clods) soil mix into the reduced hopper--and we only turn it on to load dirt for 50 blocks and so it takes no hydraulics away from pressing." - I guess Dan discovered free energy on this one:)

'''Marcin:'''

Dan did a conveyor:

http://propagelleprojects.blogspot.com/2014/06/the-conveyor-unveiled-and-on-site.html

Before than, an auger in hopper- http://propagelleprojects.blogspot.com/2014/02/auger-added-to-ceb-brick-machine.html

And mini tines in hopper - http://propagelleprojects.blogspot.com/2013/04/test-blocks.html

'''Rob:'''

Thanks, this is good info. I've read a few of Dan's blogs but I want to go back and take a look at more. I have thought about a lot of these things, and that is correct I will probably have to make sure that I'm not compressing and mixing at the same time. I may even end up doing some kind of conveyor like this to use either after the mixer or to feed the mixer. The design of this mixer may make it a little difficult for my tractor to load it while it is mounted to the machine, since my loader is small. The diameter of the blades on this mixer should be 24in, if I remember correctly. I'm figuring on only loading the mixer about half way, but I'm not sure what it will be capable off. Just to keep the soil from bridging the auger may not have to be big at all, even closer to 10in diameter.

Just for future reference, I've seen some hoppers at asphalt plants that have conveyors under them. Sometimes, what they do on these large hoppers to keep them from bridging is that they have a "dancer" plate. The dancer plate is just one wall of the hopper that is hinged and is actuated to move in and out/oscillate.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

-Code that I'm working on that uses the Arduino Micro for the CEB Press with mixer module, based on original code by several others ((see [[CEB_Press_6_-_Controller_Module_-_3D_CAD]]) (WKJCEB.ino)

-The hydraulic motor on the mixer causes some pressure spikes, this necessitates some extra delays, de-bouncing, etc.)

==With Mixer Module==
===Differences===
Outside of different hopper design - the other differences are: The only difference in the frame of the mixer version is that there is one extra hole in the primary arms, and one of the guards has some extra cutouts. The hopper support tubes are also slightly different.

-THIS IS THE STEP FILE THE CURRENT DESIGN FOR THE PRESS WITH THE MIXER MODULE CURRENTLY UNDERGOING TEST.

'''Download STEP file for FreeCAD - [[FILE:01-001-01-6 MIXER MODULE 11-2-14.STP]]''':

'''Download FreeCAD file - [[File:CEB_Mixer.fcstd]]'''

[[Image:CEB2014auger.png|300px]]

===Design Rationale===
'''Build Pictures - [https://drive.google.com/drive/u/0/#folders/0B6jW74m222OmMTJlX2VvX01vTEU]'''
#The Rotor blade design, which is attached to the shaft in the middle of hopper, and attached to the outer diameter of rotor sweep on the outer edges of hopper - allows for a '''complete sweep of the hopper''' - no soil buildup in corners of cylindrical hopper
#Anti-symmetric rotor blade design allows for soil sweeping into the middle - as soil from the far ends of the hopper is moved towards the middle.
#Reinforcement in middle of rotor blade to strengthen the rather thin blade.
#Hopper reinforcement gussets on outside of hopper are not evenly spaced with the outer edges but instead slighly closer to the center of the machine - because - the only reason those gussets are placed where they are is so that they surround the opening at the bottom of the hopper. The entire hopper is made out of 1/8" material. The only thing that is 1/2" is the base plate, which I think is the exact same base plate as on previous builds. I may have to add some reinforcement around the rim, we'll see.
#Tines are or are not twisted or bent? - Those tines are actually flat and they are just welded at off angles. It took me a while to get them adjusted so they don't rub on the hopper, but I haven't tried them with soil yet.
#How do you bend the hopper into shape? - I was actually able to form the large hopper part over the edge of a table. I had them cut slits in it, per the cut file, so that it actually forms into the multi-sided shape that you see in the model, so it is not exactly a smooth curve. Then I went back and welded the slits so it would be more solid. Then the gussets constrain it's final shape. I think I'll add some tongue and slot to the model of this hopper, because I found out, after the fact, that that would have helped.
#Geardown to slow down the auger spin speed - what are the details of geardown and spin speed? -That is something that I'm interested to see. The specs on the 7cu-in motor that I found at the shop says that the motor can get down to 65rpm. Since the sprockets are 10tooth and 60tooth, I might be able to turn the mixer as low as 11rpm. I may have the motor hooked up and running in the next two weeks, so we'll see what happens.

Do the tines need bending and/or twisting, or are they flat?

[[Image:CEB2014auger_tines.png|300px]]

Inner gussets towards centerline of machine instead of evenly spaced from edges of hopper because they are thinner (1/8") than edge (1/4"):

Geardown of auger - 5x or so:

[[Image:CEB2014auger_geardown.png|300px]]

===Design Review===
'''Outside Review'''

Anecdotal evidence says that [[AECT]] had an auger in their big hopper, but it was removed because it didn't work. And that Powell and Sons may also have a hopper.

1. "Augert will suck all the juice out of your hydraulics" - I don't think that is an issue with proper control timing. We have excess hydraulic flow during the motion of the secondary cylinder - which can be used to move soil.

2. "Requires larger hopper when in fact soil just needs to flow smoothly in the hopper" - Our goal is to help move the soil, as we know that soil does not always want to move smoothly.

3. "Soil should be mixed properly BEFORE it goes in the hopper." - This is true in all cases.

4. "The conveyor really helps us get a uniform (no stones no clods) soil mix into the reduced hopper--and we only turn it on to load dirt for 50 blocks and so it takes no hydraulics away from pressing." - I guess Dan discovered free energy on this one:)

'''Marcin:'''

Dan did a conveyor:

http://propagelleprojects.blogspot.com/2014/06/the-conveyor-unveiled-and-on-site.html

Before than, an auger in hopper- http://propagelleprojects.blogspot.com/2014/02/auger-added-to-ceb-brick-machine.html

And mini tines in hopper - http://propagelleprojects.blogspot.com/2013/04/test-blocks.html

'''Rob:'''

Thanks, this is good info. I've read a few of Dan's blogs but I want to go back and take a look at more. I have thought about a lot of these things, and that is correct I will probably have to make sure that I'm not compressing and mixing at the same time. I may even end up doing some kind of conveyor like this to use either after the mixer or to feed the mixer. The design of this mixer may make it a little difficult for my tractor to load it while it is mounted to the machine, since my loader is small. The diameter of the blades on this mixer should be 24in, if I remember correctly. I'm figuring on only loading the mixer about half way, but I'm not sure what it will be capable off. Just to keep the soil from bridging the auger may not have to be big at all, even closer to 10in diameter.

Just for future reference, I've seen some hoppers at asphalt plants that have conveyors under them. Sometimes, what they do on these large hoppers to keep them from bridging is that they have a "dancer" plate. The dancer plate is just one wall of the hopper that is hinged and is actuated to move in and out/oscillate.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

=Overview=

This page contains a list of the most up to date files that have been uploaded to the OSE Wiki relating to the CEB Press fabrication. This list is an attempt to organize the latest critical CAD data, spreadsheets, code, etc for the current revision into one location.

The latest documentation for the CEB Press is currently available for the revision 6 or "CEB Press prototype VI". There will most likely be errors that will need correcting. Please note any errors in the discussion section.

=CAD Data=

==Metal==
*'''NEW Freecad 3d model with proper grouping
**'''[[File:CEBPressJuneGroup.fcstd]]

*This zip files contains 2d pdf files for CEB 6 parts and assemblies, each sub-assembly has it's own pdf.
**'''[[File:CEBVI Fab Drawings.pdf]] - 65 pages of drawings'''
**[[File:CEBVI 2D DRAWING PDF.zip]] - may not work on some computers

*Step file for complete 3d model (CEB 6) without electronics
**[[File:01-001-00-6.stp]]

*This zip file is the original Alibre design files, 3d and 2d, that was used to make the step files and pdf files.
**[[File:CEBVI ALIBRE FILES.zip]]

*ZIP file for all CAD data and cut data for soil mixer version of the CEB Press
**[[File:01-001-01-7 ceb press mixer assembly.zip]]

==CNC Metal Cutting Files==
*These files are dxf files that can be easily imported into CNC cutting machines (i.e. laser-cutter, waterjet, plasma, or torch cutter). These files were originally introduced in the [[OSE Christmas Gift to the World 2012]]. Having these files machine cut would save a large amount of time that would otherwise be spent sawing material and drilling holes. These parts are blanks that are welded together (in most cases) in order to make the parts detailed in CEBVI.ZIP listed above.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

==='''WHO''' are you?===
*''Rob Beddingfield''
*''Opelika, Alabama''
*''rob.beddingfield@gmail.com; rbeddingfield@davismachineworks.com''
*''Current employee of Davis Machine Works, Opelika, AL (Mechanical Engineer)''
*''Picture''
*''Introductory Video''
*''Resume/CV[[Media:ROBBEDDINGFIELD 2005 RESUME.PDF]]''

==='''WHY''' are you motivated to support/develop this work?===
*''Do you endorse open source culture?''
Yes, I am inspired by a quote I recently came across by Ron Garret, scientist and early hire at Google; in reference to the fear of people stealing your ideas he said, "Even on the off chance that you do manage to stumble across someone who is as excited about your idea as you are, if they have any brains they will join you rather than try to beat you."

*''Why are you interested in collaborating with us?''
I feel that it would be a great honor to be able to say that I was able to contribute to just one OSE project. On a more selfish basis I have a small farm and I am interested in using some of the technologies there.

*''How do you think that the GVCS can address pressing world issues?''

*''What should happen so that you become more involved with the project?''

*''What is missing in the project?''

*''What are your suggestions for improvement of the project?''

==='''WHAT''' are your skills?===

*'''List all of your skills in these areas: Communications - Organizational - Computer Support - Finances - Design - Natural Building - Electronics - Automation - Metallurgy - Engineering - Fabrication - Agriculture - Energy - Architecture - Video/Graphics/Art - PR/Marketing - Education - Construction - Industry - CNC - Chemistry - Product Design - Other'''

At my current job I do CAD modeling, CAD drafting (Alibre Design), project estimating, and materials purchasing for prototype or small scale production of mostly machines, equipment, tooling, and fixtures for the construction and manufacturing industry. I have received training in welding, fabrication, metal lathe machining, and Gibbs-cam cnc software.

===HOW can you help?===

*''How are you interested in contributing to the work of GVCS development?''
I am interested in helping to produce "shop drawings". I would be glad to offer any consulting I may be able to provide or bid on prototyping.

*''Are you interested in a [[Dedicated Project Visit]]?
Yes, in the future.

*''Are you interested in bidding for consulting/design/prototyping work?''
Yes, I am more than happy to do anything I can to help on my off time. I would also be honored to bid/estimate for a quick turnaround OSE project through my employer.

Office desk

2014-09-03T18:23:49Z

Rob B:

{{Category=Home fittings}}
This is a desk that is designed to be water-jet cut out of one sheet of 23/32 cabinet grade plywood. The desk is approximately 2ft x 4ft and seems to be very stable and is also able to be disassembled. The different parts are pilot drilled with a hand drill (1/4" bit) and then bolted together using 5/16" x 1-1/2" long lag screws with fender washers. There is no gluing necessary for this desk.

This desk was originally designed to be used with the [http://www.amazon.com/Getting-Things-Done-Stress-Free-Productivity/dp/0142000280 GTD] task management system. The storage compartments will accept a plastic hanging file storage box.

Since this desk is constructed using slots, the 23/32 ply is necessary for this particular .dxf file. In order to reduce costs, you may decided not to have the extra embellishments cut out (i.e. the eagle). Some helpful info: many local granite counter top suppliers have waterjet machines that are more than capable of cutting plywood as well as steel, plastic, etc. More pictures comming soon... Why can it not be cut out with a CNC router/mill instead of a Waterjet? Much cheaper, more common and a waterjet is many many years from being an open source machine because the 40,000-100,000psi it uses requires advanced machining and metalurgy for the pump to generate such high pressures.

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.

Rob B:

What is the Assembly module?
I presume you are thinking of an assembly module for freeCAD.
We (my employer (Vanderbilt/ISIS)) may be situated to provide such a thing.

=5-18-14=
I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.
