Um - just one Q. How do you make sure there are no wax fragments left on the master before you make the mold? Brush? Vaccuum?

it depends what you cutting with, usually i use a tapered ballend and there is not need to clean up with more than a soft paint brush, but with pyramid (3 flute) or profile tools you can get compaction in narrow spaces and this si very much dependant on feed/spindle speed, too slow it compacts, too fast it melts back to the surface, in either case you need a reverse vacuum watergun to clean it up.. dangerous when you have parts with fine detail..

Hum - sounds a bit like dentistry (I think). Light cuts with fast traverse?
Does an air blast help?

Is that also like what a dentist uses?

I am being educated. Thank you.
