Hi all
I've made some moulds suitable for casting a low temperature tin/copper alloy. The problem is that the casting has a raised section at the top due to the surface tension of the alloy (similar in appearance to the old mercury thermometer). I want the alloy to be flat at the top of the casting. Any suggestions apart from filing the surface?
Cheers
