I used map gas which was recommended on the brazing sticks instructions
unfortunately the center warped some and is sticking up...

Think I'm going to try and get it hot as hell again in the center and leave it clamed down while its cooling tomarrow(unless anyone has a better idea I've never done this before).
I've always wanted a arc welder but unfortunately the electric in the garage wouldn't support it (Plus its highly likely to get stolen not a good neighborhood, already lost a 10 gal air compressor and a pile of tools in the garage)
