I've been working on a cad file for the [[CEB_Cylinder|Open Source Cylinder]]. Here is a link to the alpha stage of the file.
<br/>[[File:Universal_Cylinder_Builder_ADW.FCStd]]<br/>
The end-caps are square with a trepan machined for the tube to seat. The caps could potentially be parted so that a welding operation replaces a machining operation for the tube seat. The Rod is welded to the Piston in my version.
 
Like the universal tube builder, I'm trying to make it parameterized from a spreadsheet. Here is what the parameters look like right now:
 
Name Input (Inches) Output (mm) Note
Cap Side Length 4 50.8
Cap Thickness 1 25.4
Tube OD 3 38.1
Tube Wall Thickness 0.25 6.35
Piston Thickness 1 25.4
Piston Seal Inner, Height 0.3125 7.9375
Piston Seal Inner, ID 2.125 26.9875
Piston Seal Inner, OD 2.5 31.75
Piston Seal Outer, Height 0.25 6.35
Piston Seal Outer, ID 2.125 26.9875
Piston Seal Outer, OD 2.5 31.75
Stroke 12 304.8
Rod OD 1.5 19.05
Rod Stickout 2.5 63.5
Cap Seal Outer, Height 0.25 6.35
Cap Seal Outer, OD 2 25.4
Cap Seal Outer, ID 1.495 18.9865
Cap Seal Inner, Height 0.25 6.35
Cap Seal Inner, OD 2 25.4
Cap Seal Inner, ID 1.495 18.9865
 
Need to add a few parameters like tie-rod diameter. I think the model may need to be scrapped. Especially if one looks at the dependency graph lol. I didn't take as intentional an approach to modeling it as I could have.


I believe it is a worthwhile effort, though. A user could generate the CAD for a cylinder of different sizes by simply entering data into a spreadsheet.

Here is a file that might be helpful for y'all. Open the Universal Tube Builder file and use the spreadsheet to create tubing with all dimensions parametrized. Holes will automatically be set to 4" spacing. I can change that if you want. You can define the standoff for the first hole.  
All the exterior module [[seh4cad|Cheatsheets]] I've been uploading are looking at the module from the exterior of the building which may be confusing when it's time to install electrical boxes. Probably will just stick with the scheme for the first floor and start drawing the cheatsheets from the interior for the 2nd floor.

All the exterior module Cheatsheets I've been uploading are looking at the module from the exterior of the building which may be confusing when it's time to install electrical boxes. Probably will just stick with the scheme for the first floor and start drawing the cheatsheets from the interior for the 2nd floor.

Hydraulic DCV Comparison

Scalable CEB Circuit. Up to 3 PowerCubes with hydraforce part. GPM numbers assume 30gpm pump. Pump can be replaced with intake manifold. Scale to 3 powercubes input. Quick disconnect one and put it on tractor. Put it back. etc.
