I've had this idea for a while and finally had an hour in my shop. I tried mounting a normal carbide cutter on a holder I ground with a 20 degree negative rake. This would allow me to use standard cutters that I can sharpen on a diamond card. This one was made quick and dirty to test the concept. The result was better than I could have hoped for.
I made a quick pass on a resin blank and got the resulting finish. No sanding, as turned in the first blank picture. The second blank picture was with some plastic polish only still no sanding and no MM.
The carbide was a $2 made in China insert. Just lined up the cutting edge to the blank centerline with the tool held level on the tool rest. Comments welcome.
