If my ass-backwards mind is correct, then the rated pressure is at most 1/2 of the burst pressure for plastics. That way there is a bit of leeway between working pressure, and failure...

Well GGDT's algorithms aren't exactly accurate at high(er) pressures, so you won't get those figures... but it'll be fast, nonetheless. Also, remember that if you make the chamber bigger, you will need a larger barrel to compensate. Pneumatic guns don't suffer the problem of pressure only lasting a ...

Skim off some of the fumes hat accumulate in a sealed container.

DWV is not rated for anything. It is designed for drainage, waste, and vents. This just means that the manufacturer did not pressure test the pipe and as far as we know, it could be safe for 10,000 psi, or 1/10 of a psi and we would never know it. As a safety precaution, we advise members not to use...

Well, as I have no experience with hybrid cannons, I am talking completely out of my arse here. To get the most acceleration, I do believe that you would have to have the burst disk burst at the point in time at, or slightly before, the pressure and speed of the flame front reach their peak, so that...

... you have 8mm .12g's? Or are you referring to the pipe's OD?

ask for gasket sheet at lowes or similar. come in 6" x 6" sheets in thicknesses of 1/8" and 1/16". It's not neoprene, per se, but it works perfectly for all your sealing purposes.

Well, for #2, No. Ac motors should run at a constant 3600rpm, I believe. (Unless you're not in the USA, where the AC is pulsed at 60hz)

whatever. Forget this, lol. I'll just overcharge it and blow it up somewhere...

bah... humbug...

This little gadget uses electrolysis of water to create hydrogen. It uses regular tap water with a citric acid catalyst. when used "properly" it launches a little plastic rocket some 100 ft into the air. However, the use of electrolysis introduces the possibility of theoretically endless amounts of ...

What you need to do, is to super-polish the axle, and lubricate it with graphite. Won me the pinewood derby when I was a Scout.

You can put the hole anywhere in the valve top, as long as it provides access to the pilot area, If I am not mistaken.

The Sch.40 Cap is item number 4880K58 and is $7.45

Erm, if the current is over 0.6 mA and 100 volts, then I believe it will stop your heart, yes?
