I have been curious lately about what the most common/preferred stage is to drill your holes into the scales once made.

There are several options:
While still glued/taped together
One scale at a time
Both scales at once
Not until the wedge is in, et al.

Personally, I drill the holes while I still have the two pieces taped as one, and before finishing. I find that his gives pretty straight and consistent holes.

I guess what I am really asking is: At what stage do you yourself drill your wedge and pivot holes into your scales and what has worked best for you?
