I used abs on my golfball gun as well as a standard combustion spud gun.
I've had excellent results. this is all parts i got from home desperate though.
the cellular core makes me uncomfortable as to what it will hold pressure wise. but i use light fuel loads and a bbq ignitor with two screws. so its not terribly powerful but enough to keep me laughing.
Good luck.
PS: my golf ball gun cost me approx 30 bucks.

Good Luck and happy shooting

Colin

ok, im sorry to dig up my old topic but i have new developments

um, i found a place that has the pipe that is close to me, but they have two kinds regular pressure rated, and class T which they say is for threading. I was wondering if i could use the class T with the regular stuff in a reducing bushing. So i could use regular for the chamber, and class T for the barrel. Just in case i ever decide to thread the end of the barrel.

thats the place im talking about
page 46-47 for ABS stuff

That would depend entirely on the outside diameter of the pipe. I would suspect that you could use the class T with the regular pipe in a reducing bushing. However, the inside diameter of the Class T will most likely be smaller than the regular material. I checked out the catalogue, and I don't see any problems with using that pipe. 2" is rated for 230 psi even!

As for dimensions, I would check with the company to verify that you could in fact use class T with the regular pipe and whether or not the inside diameter is less.

Cheers.
