This is my golf ball piston valve cannon i built

even though i posted the specs before ill post them again,

1.5 inch sealing face
bolt and washer piston
barrel is 5 feet of sdr 21 1 1/2
chamber is 5 feet 2 inch pvc
all pressure rated pipe

i can only dry fire it, due to problems with the cops

tell me what you think guys

Very cool! It stinks that you can only dry fire it, though. What kind of psi are you planning on going up to?

cool video dude. Why is there so much pilot volume?? It looks like there is 2 female bushings before your sprinkler valve?? How many p s i was that dry fire?? Not a bad cannon though!

not matty there is only 1 female bushing and 1 male,
its like that to service the piston, then the pilot screws into the back of the one bushing

is was at only 20 psi, but my camera audio sucks

I can only dry fire it, but have shooten potatos at plywood and they go right through,

thanks matty and other dude, matty i cant wait to get my other cannon going(unison minds)

i plan on running it 60-100

its funny before i moved i have a cop pull into my drive way, and said what are you doing, i said nothing, he said bull*hit, , he said either you let me shoot it or i take it , i said here have at it

but when i moved cops are DICKS and i already have to pay a fine from something else, dont want anymore problems!!!

The cops in my area are okay with pneumatics... but not combustions.

I guess to many stupid kids have hurt themselves and others with fragmenting PVC.

Gotta wonder what they would think of my hybrid....

I live in a pretty rural area, where the sound of shotguns can be heard almost every day.... so no one minds my relatively quite air cannons.
There was one time though.... when i shot my 1.9'' porting piston with its 1000 cubic inch chamber at 250 psi... the neighbor almost a 1/4 away, was heard yelling "what the F**K waht THAT?!?!?!?!"

It kind sounds like a bomb going off.
