Thanks Wayne,
I'll let you know. First off, I'm hoping I can simply bolt the board blank
down sufficiently to keep it flat.
At one time I wrote some software to digitize an irregular surface, and add
in the desired cuts so that it could be machined. Probably overkill for a
PCB!
I'm thinking I might incorporate a vacuum hold down into the PCB router
plans that have been on the back burner for perhaps 4 years.
First thing is to see if I can minimize the backlash sufficiently to mill a
decent board on the Sherline mill.
