'cheap'? that much delrin will be anything but cheap. Thats not tube, you know - its obviously been machined out of a solid. At a guess, at decent quantity, you'd still be looking at 10USD of delrin to make the thing (assuming 75mm diameter, 100mm length, priced off a site at 200ft delrin quantity). Then, theres machining the rod, finishing, boring holes, tapping, machining parts, the bay mount, acrylic window, leak testing...

I guess our definitions of 'cheap' probably differ a bit. I very much doubt they'll 'pop up everywhere', and they wont be 'cheap' if they do.

They could be made cheaply, wouldnt be too hard. Id use delrin tube rather than rod, with machined end pieces to suit, oversized with lugs to reduce machining, and use long bolts to secure them end to end for sealing - uses 4 bolts to secure the lot that way. The arylic front plate would be a bit more tricky, but wouldnt be terribly hard to do. The front end piece could be made into two pieces to allow simple assembly/deconstruction to negate the need for tooling to pull it to bits.

I should cad this, im probably making no sense.
