Thank's taking time to answer! :) With a piezo the size of the gap is still important - you want the space between the electrodes to be about 4-6mm for an unpressurized mix. So do I have to adjust the gap for each mix? I assume I can't keep a small gap for low mixes because the tension would be to l...

Actually I tried a 1X mix so i didn't pressurize, i just let it at atmospheric pressure. That's why i thought that if i see the sparks when empty, i should also have the sparks when using it at 1X mix (because i've read the sparks are difficult to obtain when pressure rises but since i put no more p...

Hi everyone! I'm attempting to build my first hybrid but i'm going into some ignition troubles... Firstly the design: The canon will be a mix of a piston and a burst disc hybrid. In fact it has an O-ringed piston in the chamber that closes the barrel hole when it's down and a piece of pretty much ev...
