|Post subject:||A few supah questions for the wise|
Originaly posted by spudlover,I know I know, another guy asking about the Supah..lol I have long been an advocate of combustion cannons. Despite their small size and "low" operating pressure they perform extremely well. But slowly I have come to realize that pneumatics are the ticket for the absolute power I that I have been searching for. For about 4 months I have been researching different types of pneumatic valves. At first I was going to build a dual sprinkler valve cannon. But the talk of the supah's incredible power convinced me to build a recreation. Not only to save money, but I get satisfaction from building that kind of stuff. I would by a supah in a heartbeat if I had $130, so no hard feelings Joel. Nobody seems to know, or want to say what the exact design is, but I think I have a pretty good idea. So after a long speech here is my hypothesis. The back of the supah is 3.5" solid PVC rod slightly machined to fit in a 3" tee. The inside of the rod has a 2" hole around 1" deep where a piece of 2" solid PVC rod is glued in. A hole(7/16?)is bored through the 2" and most of the 3" rod. This whole assembly takes up about half of the tee. O-ring grooves are cut into the end of the 2" rod to provide an airtight seal for a 3" long piece of 2" pipe that serves as the piston. Not sure on the exact piston design I would use, probably Buna backed aluminum for the face plate(spudsonfire.) A modified 3 by 2 bushing inside of the tee would allow a short piece of 2" pipe to act as the inlet, and the sealing face for the piston. This was a pretty long post, sorry for all of the questions, it's late and I've been up thinking... Any help would be greatly appreciated.

Originaly posted by spudlover,Shouldn't have such long posts. The piston rod would actually have to be 2 3/8 to allow a piece of 2 1/2 pipe to slide over it. This has to do with sealing face being bigger than the pipe... Didn't even ask questions, general feedback on the design would be greatly appreciated. Thanks in advance.
