wat is the best way to make a breech barrel?

i dont want my whole barrel to move like the 1 in the 'how to's', how iv gone and done it is i cut a hole for the breech in my barrel but im wondering if i should just put a smaller peice of pvc with o rings at ither end and a small handle on the front end for the piece that seals and opens the breech.

how would you do it?

(this is for a pneumatic cannon)

http://www.geocities.com/man_o_brass/si ... reach.html here is a good one. This site has good diagrams.

i know of a simpler way, one that does not need oring grooves, it wont leak if you do it right.

slower


hope you get it

thanx il try it , it looks like it will work better than mine ,the grenade breech also looks simple but you have to cut grooves in your barrel, i dont want to have to use a new barrel again(i broke the last 1)

another thing ,you can put 50psi in a 2 litre coke bottle,do you think that will fire plastic bb's nicely?

2L coke bottle can go to 150psi.I don't go more then 100psi.

sorry i was thinking of a 1.25 litre soda bottle

Smaler bottles can take more preshure.
