first combustion

[traceur_damo]

this is my first combustion and i dont know if it is any good or not, so i am hoping all you combustion guys out there can help me. i got most of my ideas from the STAG-1 and since i cannot get a stungun i have decided to use a camera flash for the ignition, if all this works i will add a fan and direct butane not propane because i can get butane for half the price but im not sure hot to hook it up i have a few ideas running throught my head, i thought of a pin hole but then when i ignite it the flame might have a chance of coming out the hole.

The thing about propane vs butane is that even with half price on one, you will regret it later. Propane is generally much easier to handle. The methods of using propane in spud guns are tried and true also while it is still a bit foggy with butane.

Otherwise, your design looks fine as long as the pipe isn't cellular core.

Perhaps you could tap a small ball valve into the side of the chamber?
