well its not for the chamber so it shouldn't be a problem if the pressure rating is altered, and it looks like i will have to buy a heat gun aswell stoopid pipe company sending me bent pipe grrrrrrrrrrrrrr

is it combustion or pneumatic. if its a combustion simply use a heat gun and melt it back to straight but if it is a pneumatic just buy a new goddam barrel.

Seriously, how expensive could it be to get a new barrel?
Its costs me 2$ for 10 ft of 1/2"
it shouldn't cost you more than 5$ american for it.

Hey
I had the same problem once, i used a hair drier, it worked like a charm. But once again, i wouldn't trust it in a chamber, but a barrel will be just fine.

Another alternative which is one thing i did to maintain its straightness when firing (i used 15mm pvc), was i put 40mm pipe over it, and made 2 or 3 pvc washers that supported the barrel at the end, the front and the middle.

how did you straighten the pipe once you heated it up?

well i live in the UK and i have to order my pipe off the internet and in 3m lenghts so a new barrel would cost me £10 (postage and pipe) which is £10 i can avoid paying.

how did you straighten the pipe once you heated it up?

The heat temporarily weakens the bonds between the vinyl chloride monomers, allowing the plastic to be shaped, then once it is hardened, the bonds reform, obtaining the new shape in the pipe. So just heat it a bit, then while its still heated, bend it into the right shape then keep that shape till it has cooled down back to room temp, just use water or something. You only need around 60*C to make it soft.

kl thanks for them help, i wonder if rolling it on my wooden hall floor would damage the floor? ahh well i'll find something else to roll on.

p.s. i was testing my cannon today without the breech loading at low pressure and it was beasty i found the best projectile, the pritt stick!

It wont damage wood, but i wouldn't do it on wooden floors because they aren't always even. If you have a large sheet of plywood or smooth concrete floor or a smooth table, that would work well.
