@ShowNoMercy, oxygen is not pressure or shock sensitive, you are thinking of ozone.

Make the chamber a short section of 1.5" metal pipe and put a cam-lok at the back of the barrel and that would be a sweet hybrid.

You would get a lot better preformance out of a piston valve, but if this is all you have access to than go with the parallel mounting.

I have. Earlier in the thread there was a discussion about LP as a fuel, and it was mentioned that it was not very good.

Edit: what about alcohol as a liquid fuel, a several yard long blue flame would be neat.
