thanx alot guys, btw how long, i wonder, does rtv silicone take to cure. oh and i could try fiberglass resin with hardener. Oh brave new world with such people in it!

lets see, start with a multi port fitting(tee fitting) then in one hole thread in a tank valve(schrader or presta), and in the other, a valve of sorts, and a hose barb, then get some high pressure hose, and some hose clamps, then another hose barb, and a locking foot ball air chuck. assemble and thr...

well, the lead melts at just under 350*C, and dosen't give off toxic vapors untill around 400*C so mostly i just set the oven and leave it untill melted, but with rubber the smoke point, or for that matter the ignition point is much lower and i dont want another "episode" :oops: i also considered a ...

if you get the proper fittings(tank valve and the like) and a high pressure air supply, there is no reason it wouldnt work just like a portable air tank

hey evrbody, had me a idea. i have very successfully been shooting 1" rubber balls, and at the same time been experimenting with lead casting. now how difficult do you think it would be to, say, cast a rubber 1" bullet shape from melted rubber, also at what temp would a standard super ball melt and ...

quick update: super glue, vaccum, superglue gel. no problem. tested to 150psi no leaks, works like a dream, pics coming soon. thanx again to every body who responded 8)

on a previous cannon i tried some epoxy for a leak and couldn't get the epoxy to actually stick to the pvc, i re-read the directions and it was recomended for pvc, but like i said it just flaked off after a thorough cleaning, drying, and a 24 hour dry\cure time. thanx but it looks like i'll just hav...

thanx for the quick replies guys, yes all parts were sch 40 pressure rated pvc, and i used purple primer and glue for pvc from a company called oatey. The parts in question were a 4 inch diameter pipe and a reducer fitting. Does the glue ever go bad, because it occurs to me that the can in question ...

Hi all, my question is, i used primer and glue to create a pneumatic chamber, and when i pressure tested it, the seal between the fitting and the pipe sprung a leak, why? I followed all the directions given (what with the wet primer and quarter turns and all) and, is there anything i can do, short o...

you could just use thin sheet foam ( I believe the product is called foamies ) and then bend it around the projectile, kinda like a nerf footballs fins, and when it exits the barrell it will spring out and be fins again.

good ole' Georgia, lots o' space, and one would be surprised to note the number of curious rednecks who come runnin' to see what exploded at 1:30 in the a.m.

only ever broke one bone, in my hand, punched a wall, wall lost, re-set it my self, hurt like hell

been to amsterdam once, didn't buy any weed, january, most beautiful fogi have ever seen, but every one we met was sooo friendly kind of a little suspicious?

ive been getting some of my best results shooting 2" rubber balls that i get at a local party supply store, they are consistently weighted and of a standard size and shape, also warm rubber makes a nice tight seal
