Can someone give me a bunch of good ideas for pistons?
I know I want my design to have a piston, but I'm just looking for the best way to do it.

I was hoping for 2.5" but then I thought I would go with the spudzooka design which is 1.5", so I'll just take what ever the best design is.
i made a 1.5 inch piston out of epoxy the other day for my coaxil piston. the gun is drying now so i cant tell you how well it worked yet but i just put a piece of 1.5 inch pvc the lenth i want my piston to be on a sheet of rubber and filled with epoxy. after it dried i cut the mold off, sanded it so it fit in the pipe and bolted on the rubber.
Would that foam that hardens work if you made it in a mold?
My friend's dad broke one of those today while we were there and he held the hole closed and threw it outside, the can was completely encased in a mountain of foam.

It's called expander foam where I live I believe it is too soft and light, but I have never made a piston.[/code]Would that foam that hardens work if you made it in a mold?

Im using a metal can slightly longer then a Pringles can but alot stronger so i might stick a bolt through to hold the rubber on and fill the can with foam are 3"tees expensive?and i need a 3"bushing into a GB size barrel which may be hard to find.
And last thing do all parts need to be sch40?
