I now have the capabilities to make checkvalve style pistons for Co-Axial pneumatics. Three sizes are available, pistons that fit withing 2", 2.5" and 3"! So if your interested please respond, I'm going to get some feedback before I start up the production line.

Right now they're 2" Sch80 couplers with O-Ring grooves filed in with 2" Sch40 plugs ported, one with the required neoprene gasket. It's not as complicated as your piston Foxx but then again it's not pro looking...

I'll get a picture soon.

Copy & paste!

I know, it's very simple but I dont have access to the raw materials to make a "Pro" looking piston!

Deffinetly easier to make than mine. I must be the only one that thinks Sch80 is hard to find locally! Did you get your o-rings from a local hardware store too?
Can't wait to hear the results!

Hey- did you have to sand those sched 80 couplers down? or do they fit exactly (unlike the sched 40). Also, what durometer of Neoprent do you use? I think mine might be too soft, because my barrel cuts into it (like a cookie cutter). Thanks.

I only had to put the O-ring grooves in. And I'm unsure of the Durometer of my neoprene, it's the type you find in Ace Hardware, a little stiffer than inner-tube neoprene.

There's only one place in Olympia Washington that carries and they gouge me! The O-Rings are found at an Ace Hardware, they're actually 2 7/8" OD but I stretched them a bit.

you go to a plumbing supply place. Seriously, I don't know why more people don't go there. You can get 2.5", definately more probable than at a hardware store. I'm getting SDR-21 at one near me..

why sch 80? wouldnt sch 40, hell even cellular core be better? this would be enclosed in your chamber, so no dangers of exploding or anything, also the lighter it is, it should move faster? Hmmm... mabey im missing something here.
