Well Drilling Rig - water is crucial. This is a great flex fab enterprise opportunity - based primarily on integration of off-shelf materials.

could wooden 4x4s work? need extra support beams?
 
''' A preliminary design '''
 
[[Image:Well-Drilling_Rig.png|thumb|right|400px]]
 
Here is a first rendering of the well drilling rig as rendered in BRL-CAD.  The hydraulic pump (green) from the mini tractor is shown mounted with the shaft downwards on the blue sliding frame which moves up and down the side tracks.  The hydraulic pump is connected to the purple section of drill string piping which stays centered in the swivel tee allowing drilling mud to flow into it and down the drill string (shown in light green).  This purple section of piping is supported vertically by the rotating bearing assembly which rides on the top of the sliding frame.  The drill string passes through the red drill collar which bolts down to the gray floor allowing it to be easily removed or swapped for a smaller diameter collar (the square collar flange plate will be the same for all collars allowing for interchangeability).  At the bottom of the drill string a simple gray bit is shown which is just a section of 6" pipe with partially covered end caps connected to the bottom of the lowest section of drill string piping.
 
The vertical side tracks can either be composed of three flat pieces of steel welded along the edges to form a channel or can be made from large (~10 cm or bigger square tubing which has been cut in half lengthwise).  If additional ground stability on the baseplate is required, four long steel stakes can be driven through the corners to prevent it from sliding.  If these stakes are just simple pieces of re-bar they can even be left in place after the baseplate is removed (when the drilling rig is lifted straight up, or tipped down to one side the baseplate would just lift off the top of the stakes), these could then be cemented into the top pad when the wellhead is capped preventing it from sliding off the top of the well, or they can be removed for re-use as well.
 
The side tracks bolt to the baseplate and to each other with additional plates on the outside of the tracks a pair of bolts at each end (outer plates not shown).  Since the bolt holes on all pieces of this side track material are 10 cm and 20 cm in from the ends of the piece they are interchangeable with or attachable to any other piece no matter whether they bolt to the baseplate, the top crown, or another section.  This interchangeability on the side rails means you can build a small test rig with short rails for prototyping and shallow well drilling and then later on you can add additional height to the drill rig by adding on longer tracks letting you run deeper before having to break the drill string to add another section (making digging very deep wells much faster).  Disasembling the side tracks would be easy to do (only 4 bolts per section) allowing the tracks to be dissasenbled for long distance transport and the re-assembled at the well site.  In order to make room for the bolt heads on the inside of the tracks, the blue frame has 4 cm by 4 cm channels cut into each side; this lets the bolts securing the side tracks pass by without affecting the guiding done by the outside corners of the frame.
 
Please let me know what you think about the pictured design, once I have added the rest of the drilling equipment and after making any changes suggested here, I will post the .g file so other people can play around with it.

'''open source tricone bit'''
 
i think we should start thinking about ways to make tricone bits
 
Recommend you build "drag" bit, tricone or roller cone bit rely on weight of drill string to break up rock.  Most of the designs shown will not have sufficient weight on bit for tricone bit to drill rock.
 
stack plate steel?
 
rivet to housing?
 
 
'''welded pipe'''
 
want to look into rolling flat plate into tubes and welding seems?
 
 
'''casing'''
 
 
could poly pipe work for well casing?
Yes, PVC pipe is often used to case small water wells, under 8"/200mm diameter borehole.
 
[[Polyethylene_from_Ethanol]]
 
what size casing is typically used in water well?
 
You need a minimum of 4"/100mm to allow for installation of cast iron cylinder for India MKII or MKIII by AOV.  This will also allow installation of the Afri-Dev type pump.
 
 
'''mud pump'''
 
[https://docs.google.com/document/d/1PAcyqGPgeuKy5Jzi__wPtyHz5arqQmvT1MzEVwFoNDQ/edit?hl=en google doc]
 
[http://www.fao.org/docrep/010/ah810e/AH810E06.htm pump types]
 
what kind of simple designs could be utilized for pumping mud down the drill pipe?
 
possible plans for reuse of mud pump materials after well is drilled?
 
does factory farm need this type of pump for other things?
 
what were some of the pros and cons of the hydraulic pump used on the first drill attempt.
 
[[image:OpenSourceMudPumpIdea_screwpump.png]]
 
'''well pump'''
 
was the design used on first factory farm well successful? does the design need improvement?
