[TheForge] Welding cast wood stove baffle

[John Newman]

Cast iron stoves bathtubs and  radiators were cast in  high phosphorous iron to allow it to flow better.  Very few foundries will cast high phosphorous iron anymore I forget the reason it has something to do with emmisions controls
or contaminating the sand.
