your chamber is 100 in^2 and your barrel is 196 in^2 for an approximate C:B of 1:2

Is that ABS or painted PVC? I would like to know where you got the 2.5" pipe. I went to Home Depot who told me I was crazy.

it is painted PVC becouse i think ABS pipe doesn´t exist here in japan o.O, I could not find ABS pipe anywhere... And I don´t know but,It was very easy for me to find the 2.5" pipe... :idea:

Home Depot won't sell 2.5 pipe. You'll probably have to order it online from BC Arms here

It looks like a GREAT first cannon. Most people don't put that amount of work into their first creations...

BTW, some of those fittings aren't pressure rated, but that is A-OK for a combustion cannon. Just telling you before you decide to go building any pneumatics.

That's a nice first cannon, better than mine I must say, though that doesn't take much now that I think about it. So for right now how do you measure the propane?

But when i get some money i will put a propane meter...
