Folks, I am looking for some advice on how to effectively repair pits that can show when solder is used.
I make bronze sculptures of figurines using vacuum casting equipment. Sometimes, when there is a minor casting flaw I will try and fill the defect with bronze colour solder. It’s like brazing, with proper temperature control I can use this particular solder as a filler.
When the defect is filled I try to sand or file the excess to repair the piece.
This works (maybe it’s not a good way?), but I will usually end up with pits on the soldered area when I sand or file. This is a particular problem when I want to obtain a smooth surface on an arm or leg and a jewellery quality high polish on the metal.
Should I be hammering these pits into submission? This would help my frustrations. I have heard that a margin roller tool can sometimes work?
Does anyone have advice or ideas for me? I appreciate your help.
