I know on most cannons, the chamber is bigger than the barrel. Is there any problem with building something with a 1.5" barrel and chamber? I want to make something that looks like an RPG. They're simple enough, it won't be exact, but I hope to make it look pretty cool.

i guess it would look alright on a pnuematic, but it would prolly resemble a pipe bomb on a combustion

but to answer ur question i would think there would not be any problem making ur cannon that way besides it being less portable

If you want RPG make a portable bottle launcher.Also you can make a coaxial, or hybrid.

Would a coaxial with a 1.5" chamber and 3/4" barrel be very efficient?

Would it look like and RPG? 1.8mm RPG? It better be atleast 2".

Ok, I'm just throwing out ideas here. I might build a 1.5"/3" coaxial gun, I'm really lacking motivation lately, I did build that shell loader though.

i think the best thing to do is to study up a little bit, forget about it for a couple of days and something will pop into your head.

i saw a tv show about this trust me

Rambo is that a giant turd standing by a flag in that pic of yours? ive been wondering about it for awhile

LOL! No, it's some kind of G.I. Joe

looks like maybe a Marine from Starcraft.
