			==Build Notes==
			The caps as I have drawn can be easily made on a lathe and mill. I don't know if that is accessible tooling.
			How i would make this:
			Cut the plate to size and machine square. Surface grind for extra credit. Put the four tie rod holes in but make them half inch reams. Using shoulder bolts, attach the plate to a lathe jig or 2 bolts and 2 dowel pins. To make the lathe jig, press fit a piece of 4" or similar crs into a thick plate with the bolt pattern on it and weld. Face the jig on the lathe after welding. The bolt pattern should be put in after the welding operation. Use custom vise jaws and maybe a small bore for picking up the center. For the rod end cap, drill and bore the rod hole then bore internal grooves. Then cut trepan groove. For the base, it's just a trepan.
			Make those in half a day including making the jig.

			As an alternative, I was imagining "slicing" the caps into layers, like 3d printing, and then welding the slices together.

			For plastic cylinders, I would start with pvc or abs pipe as the tube. I'd go down that road before I started messing with a metal prototype.

			I'll keep thinking about it.

			Here is a version uploaded to the OSE Wiki. It should work but may have design flaws. I'm using an O-ring to seal the cylinder in the cap trepan groove. This is questionable.

			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. [https://www.dropbox.com/s/npj8me9f7l0znqp/Universal%20Cylinder%20alpha.FCStd?dl=0 DROPBOX] 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.
