Very nice looking piece of art you have there...mind posting some of the creations of the other competitors?

If you can remove it with steel wool, its most likely insignificant. Like another poster said, it would need to be deliberately abused for an extended period of time to be weakened significantly for spudgun activities.

If you have a lathe, you could probably bore it out pretty easily...I have a few extra 1/2" copper tees on hand, so once I get my lathe setup again (removed parts for maintenance) I'll give it a shot.

A large (looks like 3/4") ball valve for piloting, and a smaller (maybe 1/2" or so) ball valve for preventing the cannon from firing when the female QD is disconnected from the male QD on the cannon.

I have a length of that stuff...never got around to shooting golf balls out of it though...literally had it for well over a year.

i have 3 fridge compressors one the same as the last one so i no its good for 1500psi and 2 outhers both the same they don't look as well made tho from out side appearances il take some piccys of them and the labels and numbers on them and im open to any ideas on how i could get moar pressure im thi...

I find it interesting, JSR, that the one who always suggests that people with large guns are "compensating" has just purchased a larger car...

Paintballs will weigh less than clay. However, I don't think weight is the only thing affecting how well the projectile flies.

I think they also make .40" for blowguns and whatnot.

Apparently spherical chambers resist detonation better (claim is made <a href="http://www.spudfiles.com/forums/spheric ... l">here</a>), and the stubby nature of this chamber is certainly more spherical than most other hybrid chambers.

Bumping the screw count to eight on each plug is a good idea; the wood will not do too much in terms of blocking the pressure, but the wood with a bunch of screws certainly will do a better job.

I am pretty sure the paintball industry uses 0.68" ID 0.75" OD aluminum hydraulic tubing. You can buy 6' off McMaster.com for like $15 (part #89965K62). I use this tubing on my paintball guns, and I think it works great.

DWV does not worry me nearly as much as the fact that the pipe is cellular core. Cellular core is essentially plastic foam, and it has a VERY high chance of rupturing, ESPECIALLY when used in a pneumatic. Please, for your own safety, DO NOT FIRE THAT CANNON AGAIN. Spending more money for a safe crea...

Look up clide's recent clear valve; he did the same thing.

Yes...just take a 1/2" coupler, bore out the stop, and add some type of material to make it seal up better.
