First Time Cutting MOP

I cut some MOP today. I use my name as the logo on the guitars I build. I had purchased a precision 1/8" collet from Elaire. I checked the TIR before attempting to cut the pearl. At 3/8" the TIR was .0011". I was told that with the cutter I was using, .010" diameter, that much TIR might be a problem, but I decided to try it anyway. I set the Makita to 6, feed rate to 8 in/min, and depth of pass to .005". The pearl is .055" thick. It took 51 minutes and 21 seconds with the following results.
