Yeah it is open cell foam, so I'm good there, I had tried closed cell at first an I smashed it a few time with a hammer first to make sure it would withstand and it flattened out. This rubber stuff withstood the hammer :)

Alright, so this thing is finally completely done. I added a red and black paint job, as well as redoing the piston housing and adding a much better bumper. Needless to say, I am one happy person right now :D

Piston is a solid piece of nylon rod that I machined down with my lathe. And the flip flops thin is an awesome idea, may just end up doing that.

Yeah I couldn't find the schedule 80 parts I needed (specifically the female adapters) so I will end up redoing it in schedule 40 parts, my question for you guys is if you think the new bumper will do a better job versus a tennis ball that was bottoming out with every shot.

Thanks

Yeah I'm *relatively* certain that schedule 80 fittings have the same inside diameters as schedule 40 but larger OD, if I'm thinking correctly. Then the pipe has a smaller ID same OD.

Oh and also one thing I forgot to mention in the above post, since I know that my piston fits well in 2" schedule 40 pipe, do you guys think it would be okay to put schedule 40 in schedule 80 fittings, assuming I have a decent bumper? And also technician, doesn't it help to have abs for this kind of...

jsefcik I'm not getting the link to work, but it certainly sounds nasty. And MrCrowley, yeah I think that with a more suitable bumper and a schedule 80 housing I should be alright, and I'm not totally understanding what you mean about making the PVC "concave". Also, do you guys think it's okay to ha...

Alright. Well, my piston blew out the back of my gun. I didn't have time to get pictures yet, but I am showing you guys basically what happened on an old picture. The red circle around the female adapter is where the damage happened. Basically, it blasted off the threaded part and left the solvent w...

Wow. Nice, clean hole at least. Thankfully that didn't ricochet like the golf balls were.
