I did discover one significant issue causing problems with my initial milling
attempts. Drum role..... :-P
What I thought was a end mill was in fact, a ....... drill. Correct size,
wrong bit. Sigh. (As I slap myself.)
I do have the correct carbide end mills, so I may give this another try using
the *correct* bit this time. I expect the "skating" should be significantly
reduced if not eliminated.
With a red face...
