Cooling Rack - Part Two

I've been hard at it... I assembled the whole front section of the rack today. First I did the driver's side:

I have completed the tuyeres (air nozzles). This is where the combustion air enters the hearth. They are made from 3/8" pipe fittings - a short pipe nipple, a cap with a hole drilled, and a reducer that the nipple fits into. This way I can change the lengths and nozzle sizes very easily if I need to. I have to connect the seven of them with some sort of manifold. Probably will just be another ring welded onto the flange.




I welded the pipe fittings outside the hearth, and then cut them off nearly flush. This leaves room for the intake manifold:
