Drill bit size for #1 gauge tuning pins

I've been double drilling block since this first appeared on the list
about awhile ago.  It really does make a difference in terms of even and
controlled torque on the pins (assuming the pins are equal in
diameter-not always the case!) and takes away that stress of controlling
feed speed.  Plus, since the final bit takes out so little material,
they last longer.

 I'll try this on the next one.

If you double drilled, most of those problems would magically go away.
