The concept is pretty much a tiny rocket motor to light the larger one!
I used GOX and Propane ignited by the sparkplug, I had a few issues though which as you can see in the video looks like more a series of little explosions rather than sustained igniton.
My fuel/ox oriffice sizing was too big and was blowing out the fire, so to speak,so would only ignite when the sparkplug fired, I think the impingment might have been abit off as well, and my sparkplug was not pulsing enough, I had it hooked up to an electric fence unit, was abit slow. So next test, smaller oriffices, faster pulse and see what happens!
If not I got another design which I'll machine up over the weekend which should work for sure anyhow!!
Should be exactly like this (Masten) next time I try!
