How far do you need to shoot them? How big is your compressor, and how big is your budget (yes I know that you said you don't know but it would be very helpful to know)? The hardest part would be finding a way to shoot soft irregularly shaped objects, like t-shirts semi-automaticaly. It would be eas...

It depends on the setup of the cannon. A picture would help us out a whole lot. And if it is threaded then all you need to do is just unscrew it and put more teflon tape on it. There is no need to restart or chop up your cannon from what I understand. Once again a picture would help tremendously.

Well you said that it was on a threaded piece. Therefore you don't need to restart. You just need to unscrew it and then use 5 or 6 layers of teflon(you need to use more when going from PVC to a metal or vise-versa). If that doesn't work than you must have cross threaded it or something, and you wou...

Man, this sucks. I think I was finally getting a little respect at Spudtech, and I was finally and "Advanced Spudder" and now I am nothing again. Its not that I hate everyone at Spudfiles or anything like that, but this site has so many stupid members that just kick up posts and do nothing useful be...

Yes all parts need to be Sch. 40. If you really wanted to you could use Sch. 80 but there is no reason to do this in a typical launcher. But yes all parts need to be at least Sch. 40 and Pressure rated(make sure the fittings say NSF-PW and not NSF-DWV) I would not pressurize it over 125PSI because o...

Yeah I know as I said above

yeah there is alot of DWV in my old one. It even has a super high tech chamber made out of Cellular Core ( ). I didn't know any better at the time so I used whatever was the cheapest.

Wait are you talking about the old ball valve "T" shaped one. If so I know this and that is actually why I built my new one. If you are talking about the over-under one (the one this topic is about) please tell me where because I have thoroughly searched every fitting twice now finding that all of t...

Where are ther DWV Fittings BC. I just rechecked all of them and I am pretty sure none of them are. edit*Oh just realized that you were propbably talking about my old one. Sorry if you were I thought you were talking about my new one, and I really don't want to have to take it apart. But yeah there ...

Yeah I've been a member a Sputech for about a year now. I havn't posted too much until recently though.

I have built one cannon before this one but I did not design It. So this is my first cannon that I have designed and built. Specs: Chamber-16"by4" Barrel-(detachable) Sch 80 3/4" by 5'(paintball) and 1 1/2" by 6"(potato) Valve-3/4" Aluminum QEV In two of the pictures you can see my other cannon that...
