This is my first working piston cannon and my first post on spudfiles.
I usually only pump this up to around 90 - 100psi and i made two barrels.
- 1 1/4" potato barrel - 2" sleeved into 2"PVC (golfball barrel)
Specs:
- 2" chamber
- modded sprinkler valve (pilot valve)
- plywood piston (i got the idea from MrCrowly)
shot a golf ball 350+ yards

Nice cannon! And welcome to spudfiles. It looks a little akward to hold though.

Cool, And I think You topic isnt getting much attention is because It was titled the same as mine, and most people have already seen mine, so You might want to change the topic title.

i like the cannon but i see some DWV --- i one on the pilot is a easy fix but the one on the front is going to be a hard fix and maybe a cannon ender
p.s. you should drill and tap your psi gauge on a fitting so you more then just one layer of pvc

100 PSI is still a hell of alot of pressure on non-pressure rated fittings, I would say around 60-80 psi, just to be safe, because we all know how catastrophic it is when PVC ruptures.

nice cannon, and i have a input on the DWV, you have it on the worst possible places since those fittings take the smack of the piston
