Before costing

I just finished building a 5 gal. air tank forge it has an interior area of 358 cubic inches with one 3/4" burner  and had some time to run the forge and check out some temperatures.
It took 3.25 minutes at 2 psi ball valve 1/2 way open to reach 1550 F and the same 2psi ball valve all the way open 7 minutes 2000 F
This forge build far exceeded all my expectation
