Counter-bearing drag

[John Ross]

Hi Ron,
I have always drilled the block outside the piano.
Using a jig, so that a small back angle is there, and I have a stream of air 
blowing on the bit, for cooling.

I have forgotten. :-(

Do you have a modified drill press to drill the block, or do you do it free 
hand?
