I have used metered propane for a while now and it has worked great, i now have a canister of mapp and every time i go to inject it whatever im shooting comes flying out of the barrel just as i open the ball valve, any help?

havnt measured anything yet but much more than befor, probably twice as much. and what would be a good silencer packer? i was thinking of using steel wool, works in cars

yeah search it up next time please

Nothing more than what they said, propane, stungun or circit, and fan

I was at canadian tire a while ago and i was wondering if MPS gas could be used in a cannon? Does anybody know the fuel to air mixture and if it would be safe?

thanks all of you guys, and as everyone said, Tada Biger Barrel

K thanks guys, for advise and having it so fast

Most likely just a bike pump, My next gun is going to be a regular combustion with sch 40 pvc. im making it an over under rifel style, a 3" combustion that goes to a 1.5" stock and such, and i am then conecting it to one of the bolts and golfball barrels off of bc arms. just befor the bolt i plan to...

K i read up on it, from what i understand i put the disk in the middle of a union then pump up the chamber to whatever psi, add my combustion fluid, and spark. the force of combustion should break it, is that right?

k thanks

how would you set that up? Im a noob at hybrids

In a hybrid would you just use a regular modified sprinkler valve, like in a phnematic, or would it be different? And how would you set it up to spark and open at the same time?

duck tape Does Nothing! people always say something like that, just wrap it. it will not help at all, and yeah i would do it with what u got, and if u are looking for the sch 40 pvc order from www.Mcmaster.com(only if u live in the states,im in canada and they dont ship here)

if you can affored it, go for it!

stuff a potato down and pour in all that extra pocket change, watch for shrapenal!
