I have a can that fits very c good in a 3in pipe. I'm planning on melting some hot glue, and sinking the cut tennis ball into the open end while the glue is still hot. As for the sealing face, you know the puzzle peice like flooring that kids play with? I was thinking the flat side of that will work.

I just realized how simple the could be. I'll get a small section of pipe that fits into the t connector, then put some pingpong balls in it, cover on end with some paper, fill it with epoxy, then cut up the inner tube and superglue a few layers to both ends, After removing the paper. Will 3 or 4 la...

Its light grey. An endcap covered in melted rubber could fit perfectly. 1" caps fit EXACTLY into 1.5", I use to use them as ammo. I didn't even need wadding. I'm sure there's a pipe size that comes close enought to free improvise it. EDIT: I posted that, but forgot to metion that if I can find 1.5" ...

I have a one...

Help with my first piston valve
I need help making my first piston. Most of the existing guides require sheet PVC or O-rings, I have neither. I was planning on making it out of sevral cicular cut-out sections of wood, then cutting up on of the rubber bike innertubs I have lying around, then epoxing it to both ends. Will this work?

2.5" barrel would be bad as it is rare unless bought online, and fittings are also rare. A golfball will fit in 1.5" SDR-21 if you are American, or 40mm PN18 PVC if you are Aussie/NZ etc Well I did find a 2.5in barrel to day, forgot to look for fittings though. A golf ball fill not fit in a 1.5in b...

This is a great tutorial. I suggest omgimonfrie2 should start simple when he has gained enough knowledge then build a piston valve. It is a great learning process my friend. I was going with a 2.5 in. barrel until recectly, so a ball/piston valve would be too restreicive. I'm not saying I'm a noob ...
