hmm... well then I guess I was pretty much right on with my original amounts, which is kind of a bummer cuz I was almost hoping to be off by a little so I could get more power by correcting it, but I guess I'll have to find other ways to improve upon it... I'm sure that shouldn't be too difficult :roll:

Nice gun.

Where'd you get the big hose clamps to hold it together? I've wanted to use them for the same thing but I could never find them.

Nice looking build, I guess some of the posters in this thread, I.E. one in particular live to diminish your accomplishment. Anybody can research endlessly online to find answers, only to post here and sour the awesome cannon you have shown us. So anyway, keep up the good work! :twisted:

What does such a cannon cost in USA, round about?

The prices for pressure rated pipes are damn expensive in Germany :x
I'm sorry, my English is not so good but I'll try my best!
