I love the Tigers. They have always had so much heart. I always barracks for the underdogs in a match.

hey guys iv had alot of troble getting the ball valve to connect to the bottle so wat could i do... When i file the thread down on the bottle and put tape on it it connnects but has a slight leak!

Would i be better to use Poly as my chamber, like a 1' 20cm piece?

I could only get a plastic ball valve, ($25!!!) and it dosn't cut a thread!

Thats the problem mate. Its a plastic ball valve. you NEED metal otherwise the the thread wont be cut in the bottle. If you can get a poly chamber then go for it!

Come to think of it. You will need a large piece of poly...Like 40mm but I dont think it comes in that size... Dang... Hmm...

Poly can take a hell of alot of pressure. around 500psi

Large diameter. You need a decent size chamber or your not gonna get very much power at all. the 20cm of 1' would be good for like...a 20cm or less sized barrel.
