This was my first full featured combustion. Built out of ABS, (4"x12",) it has a chamber fan, detachable propane metering, and stun gun dual spark ignition (not shown.) The rings on the chamber are sharpie, I used those to position the electrodes (screws.) The propane meter uses quick-disconnect fittings so the regulator and torch head can be used on multiplier launchers. The hose (fuell-line) used to be 3' long but was shorted for use in the STAG3.

Awesome gun but one problem...ABS is not pressure rated. It could weaken and explode. I'm not being critical but that is very dangerous.

no its not, ABS has been use MANY times in combustions, and aside from high powered fuels i've never heard of one exploding, there's not much danger there if you built it right

propane is a high powered fuel, is it not?

Propane is powerful. But I think spudshot is talkin bout oxygen and acteylene. They are highly combustible compared to propane. Note: oxgen doesnt blow up by its self but when mixed with other fuels is way super duper powerful.

the problem with acetylene and oxygen is it doesnt combust, it detonates, the pressure spike is too great for PVC and it will explode

yeah thats y you dont hear about people using it as their fuel

Theoretically, it would be safe If you didn't have a projectile. THis way, the gas would just ignite and blow out the barrel. But if you tried to launch a projectile, emmm, how do you say. PVC DEATH!!!!

What would happen if say you used it in a steel chamber that could handle it

Hmmmm, ever hear of carbide cannons? Those use the same principle, but they don't shoot projectiles. It's just to dangerous because acetylene is very unstable.

ever hear of oxygen-acetylene torches? they're used to cut through steel, so i'd be hesitant to even try it in steel.

Spudshot, that response to that question has been shown to be wrong so many times... well, I'll leave out the inferences one might make about you.
Anyway, propane tourches are pretty effective at burning through PVC. Odd that we can use propane as a launcher fuel when that's true...

you know, if you gave that thing a 2 foot long barrel, you could fire a little bit further, and accuracy would be unbelievable. also you could make clips to the bottom or where ever so you would only have to hold one thing instead of having to fumble around with the tank and shoot the gun at the same time. 1 saftey idea though, with guns that have a permenant propane attachment set-up, you should always have a backflow valve just incase something goes wrong. because im sure an exploding propane tank would probably ruin your day.
