Flame pipe venturi built by jamesrl on that forum.
Fuel pumped by £1.66 washer jet pump from China.
Fuel here is an unknown mix that smelt of diesel, engine oil and something else. It runs on anything that’s thin enough to pump at a decent rate. We ran veg oil mixed with diesel and engine oil mixed with diesel – it will probably run on neat veg if it’s heated first or a more meaty gear pump used to get the flow right.
Doesn’t need a monster compressor to run either.
This was with a higher fuel flow to try and get the heat around the aluminium melting pot, see other vids for different fuel/air mixes burning.
