Thread: Bismark with "Garibaldi" scales

I used a tiny ( think dental bit) ball end cutter. Once the main area was relieved I then switched to a square end cutter in a typical router style application. Couldn't breathe while doing this as one little slip and all would be lost. That plastic against a high speed cutter disappears rather quickly!
A bit of a balancing act as too slow the bit wants to grab and walk.. too high and you just make a melted blob on the bit. Diamond cutters just wrapped themselves in melted plastic. Open style cutters at around 20,000 rpm seemed to work best.
