Glad your having fun!
Took another crack at the face mill, and got much better results at ~400 rpm and 20 or 30 mils depth of cut is much better than 5 or 10, which mirrors my experience on the lathe. I could probably bump up the rpms to 600. Rear side of the mill does drag a bit on the surface but nothing you can feel with your fingers.

Do you find a big difference in results using inexpensive tooling from ebay sellers vs. more expensive name brands? Durability of HSS end mills, carbide inserts, etc? I've certainly found that good drill bits outlast cheap ones... Do you have a favorite supplier/website for lathe and mill tooling?

Thanks for your help.
