Thats a nice small caliber simple design but... why so much tape it would look hella better without the pate and a new paintjob. On another note do you have any damage pics?

the tape is because i dont have any paint at my mothers house, and everything for it was bought for under 30 dollars. i am a minor also. damage vids coming soon, i still have to make ammo.

i reccomend some 3/4" dowel with the blunt end of a screw screwed in. very good ammo for me :D

sorry i cant post a vid today.. i had some difficulty putting the right amount of fuel in there and i just ran out. tommorrow or the next day i am going to be going to lowes for some fittings for propane injection and compressed air injection. i have to do all this with out my dad know as he threw out my first one for shooting an old paint can. does anyone know how much a foot of hose, some barb fittings, two ball valves, and copper pipe would all cost together?

dont forget the torch head, regulator, and tank of propane. why are you going to use compressed air injection? i hope to god its for venting

Me too! And for the propane injection you dont "need" a regulator, I just use my calcluations set at 90PSI (Tank pressure at room temp).

well i just would'nt want him to try a 3x mix in that thing :lol: i strongly reccomend use of a regulator when the cannon is this small, just a little bit off and youll have an over mix, and you'll have to vent and start again.

well actually the compressed air injection is saving time when i use aerosols. if i spray to much, i just add a little bit of air. then when it fires i can vent with it.
