I'm sorry for such a late reply, been having some computer problems for the past couple months.
Yes, indeed it is a combustion, with a large majority of its parts supplied by a long-stemmed BB lighter; The combustion chamber was the lighter's butane tank, the igniter was (obviously) the lighter's igniter, and the wiring from the Peizo to the spark gap was also from the ignition system in the long-stem lighter.
The butane fuel system was previously a micro butane torch, the head was screwed off right after the venturi (the component that combines the fuel with atmospheric air) and a vinyl hose attached to its end, with the other end attached to the 1/8" ball valve. Opening the ball valve after firing, twisting the torch body to engage fuel flow (leave open for two full seconds), twisting it back off, then closing the ball valve would vent the exhaust gas from the previous firing and fill it with the stoichiometric Fuel:air mix, and would require only one more step, which would be to load a bb.
The butane torch venturi and valve dispense with the nescessity of acheiving the perfect Fuel:Air mix manually; It does it for you. And yes, a magnet was used to keep the BB in place (not visible in pics).
rna_duelers- No .

Could you use copper for the barrel, and is the magnet on the outside or inside.
