Thanks for the heads up. I found some cheap single sheets of 0.010"
and 0.026" at electronics goldmine and I am currently awaiting
delivery on those for testing.

I did price out diamond core drills and gacked at the $50 - $150 price
tag. Between the price, the dust issues, and the potential for the
cut-outs to get caught up in the bit I am going to keep this as a last
resort.
