this is my cool combustion cannon it is made from sch40 pvc conduit the clean out cap is is an airhockey table thing to fire u stick a stick lighter in the little hole it uses propane to fire it is my first combustion gun

interesting so its just a length of pipe with a cap on the end dose it work good?

[666lucky693]

its a 2inch pipe that goes into a 1 inch the two inch pipe is 16 inches long and th 1 inch barrel is 26 inches long i guess it fires ok but the first pneumatic gun i made was 100 times better it would fire a paint ball out of sight

You should take apart that lighter and use the sparker, it'll work much better.
