Well the build is pretty much completed. A little sanding, painting and nice door handle and its done.
Have burned it 5 times about as hot as it can get. Metal has pretty much seated in, no more creaking or popping. Got all the leaks welded up and the door sealed.
Played all kinds of games with the air & pipe dampers. Could not get it to flash back. So that is not a problem.
You can have all the heat you could want out of it. If damped down correctly a 3 to 5 hour burn should work out. Maybe a little longer depending on how well you get it adjusted and the type of wood. Having a thermal mass of almost 200 pounds and with a good bed of coals, it should put out all night heat.
Would I build another one. Yes but a lot simpler with fewer parts.
Having worked my way through this one, planning would be better as well.[/QUOTE]
Hopefully, your welding technique improves as well......
