Doing it Right The Second Time Around
Posted: Tue Jan 06, 2009 3:00 am
So some of you may have seen my last attempt at building a cannon I dubbed Big Boy.

It showed incredable (atleast to me) potential but than it was brought to my attention that not all PVC is created equal and Big Boy has been retired. So now im looking to avoid any more problems on my next build. I read the Wiki on pressure rated PVC and found a place that I believe sells it. BUT before I go out and spend more money on PVC are there anymore things I should be looing out for? Any problems you guys have run into would be great to know.
I also have some specific questions.
1. Will standard PVC purple primer and clear cement work for this application?
2. Assuming I use all pressure rated parts what max psi will my cannon be capable of?
3. How is the best way to have interchangable barrels that will work from large sizes like 3" down to 1.5"?
4. As mentioned above are there any other potential problems I should be looking out for or tips on building a good cannon?
Thanks all in advance!
