I know it is possible but can i make a propane system that works on my really simple combustion? i want one for faster shooting. I wanted to use those little lantern canisters. C:\Users\Connor\Pictures\coleman.jpg Any help would be appreciated greatly.

Err, I don't understand what you're trying to say.
If you mean "can I meter measured amounts of propane into my combustion gun?", then the answer is yes. Look in the cannon discussion forum and you will find all you need to know about fuel metering.

I'm not sure how much faster it would be. Someone who's handy with that endcap and starter fluid could probably get close to the speed of opening and closing a couple of ball valves...

Then again, I built but never used my metering system, so whadda I know

My suggestion is a double barrel launcher. I know I have seen one somewhere on this site.

they use propane tanks like that for air for airsoft guns i guess the same principle could be applied to that to load fuel instead of building pressure
