Hey, I built a TB cannon with a mod. sprinkler valve. Its an okay gun but it only shoots a TB about 75ft at 100 PSI. Its a 2.5" chamber and its about 1 1/3 feet long.... and this isn't good enough for me ( being that it only shoots 75 feet) I expected much more for the money i spent. So, how can i beef it up?

if you can (budget wise) make another barrel at least 5' long, that should increase your accuracy and distance a fare amount :thumbup:

EDIT: you should have put in a female adapter so you could interchange your barrels...you still can but would have to cut off your current barrel :?




oh, and jdax?? you see my tattoo design i drew for up for you? took me like 3 hrs lol, but it was fun :P

Yeah. Heres the prob. Its a basic gun thats gonna be put inside of an AT-4 style cover... so once i got everything to work, i was gonna just fill it w/ great stuff and make it really solid. But... the housing is 5' long itself. So what should i do within those perameters?

if i understand you correctly, this is what you should do:

modify it as much as you can (fit as much of the gun inside the structure as you can) and re-paint it all the same color so the external pvc matches the original color of the outside structure. :blob7:

Well I think a sprinkler valve is a bit to small for TBs.

a 1" sprinkler valve at 80+ psi should be fine for TBs

upload them onto the websight and then post
