Your a very skilled individual Richard, I just love your workRasper wrote:I finished welding on the Queen's head. It was a bit difficult. Using a borax flux I get a bright orange flare that keeps me from seeing the puddle very well. I have a lens that I use for gas welding aluminum at my California shop that filters out that orange light, but it cost 187 dollars so I am not going to be buying another one. I just added a lot of filler rod so I would be sure to have enough build up. Then I cut it off with a chisel. Time consuming, but it's better than having to re-weld. Welding this stuff takes a lot of time—and propane gas. I have to heat the entire casting to somewhere near dull red with a propane burner in order to weld it. This bronze conducts heat like you wouldn't believe.
