I just want to say that I was intimidated by building a burner/forge, but this was ridiculously easy. I couldn't find a tap-wrench to fit the 1/8" pipe tap(they were sold out unless I wanted to buy a $60 tap wrench/bit kit.) and I was stupid and wanted to look down my drill hole before using the tap, so my first attempt was not quite perfectly vertical, but the 2nd time I did it exactly according to directions, and it looks great.
My flame keeps blowing itself out, or "wooshing" at low pressure, but I am pretty sure it is just rich, and and I need to trim the mig tip down more. Just waiting to get a forge before I final-tune it.
Is there a "minimal viable size" for a forge with this burner? I have a bunch of fire brick left over from a pizza oven I built, and want to mess around with while I await my kao-wool, and was going to build a small brick-pile forge for a small knife I'm working on, so I don't need much space at all.
Also, just out of curiosity, what effect would it have if I used my off-skelter original T, so the injector wasn't spraying strait down the pipe?
