That'll be plenty big enough. How's the rest of the build going?
Good now that we started working on it again. We cut out the big tank end with an oxy acetylene torch. I don't have a pic of after we finished grinding and getting it matched up well but it turned out pretty good. There's only a small section on each side where there's a gap. Not bad for winging it.
We also cut out the holes up top where all the valves were and cut out circles to put back in. Hoping to get a good amount of welding done this week. We're also getting some pricing from a couple different steel suppliers to see how much the plate would be to make it a reverse flow.
Do most people use 1/4" for the reverse flow plate? How far down do you put the plate and how much gap do you leave on the other side for the smoke to come up through?
