So I am working on lost wax casting. The current project is to make "signature emblems" for my furniture pieces. I plan to cast them in silicon bronze with a penny for the date. I picked up some ingots of silicon bronze. I would like to cut them down or granulate them for casting.
How would others cut these? I could use a hacksaw (sounds like a horrible experience if trying to do a a single time). I could use my WW bandsaw but I think i would wreck the tires). How about a 4-1/2" angle grinder? Other ideas?
Has anyone granulated bronze? If so, how did you approach it?
I picked up a vacuum investing set-up and a centrifugal casting apparatus. I have no container / shroud for the centrugal arm. Has anyone made an enclosure? If so, how did you do it?
