yea, i made one of those, they work great!

what is your peoples problem with ball valves? Geez!, they work good, i use one.

yes, its pressure rated, said right on it. letters on it are gone due to me scrubbing them off.

i just used a yellow foam golfball with a bolt in the middle, at 80 psi. BOOM! clean hole right thru plywood, works good.

call me dumb but can someone explain what a mortar gun is that i see alot people talking about on here and what is it used for?

so pnumatic being powerful, can u put a spud thru thick plywood like u can with a combustion ?

yea, very true, my pnumatic is pretty loud. Loud enough for me anyway. Makes a good boom. Combustion ones are no longer fun for me after building a pnumatic one.

thats what im going for is power, more damage to stuff..lol

yea, my brother was saying that combustion was better, but air all the way for me, this is the best gun ive built, i have a combustion but never use it now that i have an air one.

what one do you think is better?

idk, that would be a little wierd if u ask me, its all about what u like tho, so go for it..
