this seems like a great ide but u need something to chaber around the bolts or the projectile.

i got a question is a direct curcut better than an alt curcut?

yeah you can but use some kind of paint prime with alcohol so the paint will stick. try to use flat paint itt sticks more. if you want gloss use a lear coat of gloss paint over the flat.

ther will be a loss in accuracy becuase dead space creates the spinning or unbalance of air flowing but the power of the cannon will be not phased to be noticed.

umm i dont think you would ant to make a chamber u might wan to use epoxy to reinforce with some kevlar if ur using aabs( do not reccomend) but ur better off just using a good ole pvc or large water bottle chamber

DO NOT TAKE THIS POST SERIOUSLY.

there is really no telling you first have to find out what guage the metal is then do the math i forgo the formula for psi. length x width x guage=...
then sivided by air consumtion something liek that.

the best thing is to sleve the chamber but leave some pipe out to attatch to triggering mech. uese some type of teflaun or heavy cotton. first put a layer of tight fabric then a lose layer then antother tight layer on top then (this can get repettative) add another loses layer. the first 3 layers wi...

yeah u got a lil toooo much dead space and too muck triggering mechs. well all is not lost you can probly use the middle pipes still! 8)

the mythbusters use 50psi to start then whant up to 130psi . it didint go very far but the barell exuaster that u may fit on it can add an extr kik... try no to get the ones with the handle. the dead space by your triggering device might cause hige back fire/ recoil and poor preformance.

well it looks like you do work nice workshop!!

umm it might be very hard to buy pvc out the most supplyers cut off trade with the middle east cuase the pvc was used for the construction of motars9 bombshell launcher look! some how they fgiured this would stop some terrorist from shelling their enemy enemy.. keep on looking but it would be expens...

well i made something of the such but you can get them empty from the home depot or lowes. this company named harbor line or harbor freight has them i get the magazine every so often i cant remember it just try to google it.

go to auto zone ore kmart or even wal mart anywhere that sells tires or bikes. schrader caps are not really effective ecpecially on spud guns they may cause injury if the schrader gives out and backblows.

yeah its best to get pressure rated becuase, then the spark ignites ther is and explosion in the chaber and after a while it may start to crack trust me cracks with propane is noooo god> 8)

can u explain to me how the triggering works i dont get it. if one wnd of the blowgun is not attached to the air chamber then whats stopping the air from going out?
