I just finished building your 747 burner, I didn't have a bit of 2" pipe in the scrap pile , so I used a bit of 2 1/4" exhaust that was under the bench looking for something to do @ 150mm long
The little piece of pipe over the hole I made a bit shorter than the length of your thumb nail :laughing-rolling: :laughing-rolling: :laughing-rolling: :laughing-rolling:
and it seems to me that IMHO the flame is a bit yellower than I sorta expected, and Its not very loud at all ( maybe it's my hearing :( :( )
What sort of output does your gas reg.have, The one I raided outta the bbq say 2 kg/hour on it , Is that enough or is it the wrong reg ? :think: :think: :think:
Any advise welcomed ?
Cheer

nahh you need a HP reg i think to get the most from big D's design.
more like 4-8 kg per hour
or muck about with gas hole and air hole sizes i think
got a gas hose without a reg...... lol :angry-extinguishflame: :angry-devil:
