I don’t think those can be used with non-precious metals. I seem to remember the JSM people getting really unhappy when someone brought some mild steel over there in the past.
That is specifically why I stated that I would be using new buffing wheels and compounds specifically for this purpose…to prevent contaminating noble metal buffing wheels. I need access to the rotary tools, only.
Malcom is correct in that we specialize soft metals Silver Gold and Bronze only. Contamination is a big issue for our department, thanks for asking first!
For the work that I am doing, the tools, light and work bench in the jewelry lab would be ideal.
I really don’t understand the issue so long as I use new buffing wheels specifically for my application?
