Re: Supercannon II complete
i made a supercannon II. Except mine is smaller with 3 inch pvc and only 3 feet of it. The rest is very similar though. Also, i did not put enough glue on the joint to the 3 inch pvc from the side you pressurize it so when i got up to 100 psi the end shot off life i rocket. But more importantly it ripped the hose out of my air compressor. I am mainly planning to shoot the lifeguard at my pool with it because he always complains about how i shoot him with little water guns.

Re: Supercannon II complete
Oh dear...
I would suggest you make sure it's NOT going to shoot parts off before you aim it at anyone.
Also you probably shouldn't use it at close range anyway, it could cause an injury. I'm not sure what a 'safe' distance might be, but if you're having to angle the gun significantly to get the range, then it's probably safe.
If you're looking to shoot people at a pool, SCII's probably overkill unless it's an olympic size one. What bits do you have left over (I'm guessing pipe at least)? I'd suggest trying to make them into an APH or similar, that would be more suitable.
Also, if you intend on firing pool water, I'd try and find out about the compatibility of all the parts with it. Not everything is designed for such.

Re: Supercannon II complete
And what if the nozzle shoots off? Or what if it's just so powerful that he gets bruised or injured anyway? Then you'll have a much bigger problem on your hands.
Ben never uses water cannons in water wars. Neither should you. Build an air pressure homemade if you just want to soak somebody.

Hey swirlycurly, would you mind posting some pictures of your Supercannon? I've never seen another completed one so I'm interested in your version.

Re: Supercannon II complete
yeah sure. First ill have to figure out how to post pictures. I fired it for the first time with no nozzle and the kick back slammed the gun into my chest and it hurt a little and cut me.

Re: Supercannon II complete
It is essentially the same thing i used about three feet or 3 inch pvc for the PC and i didnt use a check valve because i felt it wasnt necessary. I just got a different sized piston on Mcmaster-Carr.

Re: Supercannon II complete
Wow, that looks like a powerful but compact remake. What type of fire hose nozzle is that - 1.5" threads and 0.5" aperture? It looks solidly attached so I'm not sure where it shot off.
At any rate, I'm sure you got a lot of output with that nozzle and near 100 PSI. From what I remember Ben never took Supercannon II that high.

Re: Supercannon II complete
it is the same nozzle as ben. I have been wary to pump it up to 100 psi since last time i did the back of the gun shot off. (it also ripped the pump attachment thing off my air compressor so i dont really want to pump it up by hand). I have to find a better schrader valve because i hammered in one and glued it but the glue is cracking and it is leaking.

Re: Supercannon II complete
That's why I use threaded schrader valves and air couplers. They're much easier to install and more reliable than other types. The rubber seal ones Specter mentioned in another thread are good too but they're not likely to handle high pressure as well as the threaded valves.
Check out this picture to see how I attached a schrader valve to a water gun I recently built: http://forums.sscentral.org/attachments ... 1217732146
It's basically a threaded schrader valve, a 1/4 inch female to 1/2 inch male threaded bushing, and teflon tape.

They are made of stainless steel for car rims. Package says maximum recommended pressure is 150psiThe rubber seal ones Specter mentioned in another thread are good too but they're not likely to handle high pressure as well as the threaded valves.
