pinblock drilling angle, with pin bushings

[Michael Spalding]

Yes, that's essentially how I set it up.  But I've been pushing the angle
to the high side, anticipating that it will yield towards the pull of the
strings over time.  I'm re-thinking that position, in light of the
bushing-to-hole alignment issue - might try lower angles, at least on
bushed pins.  Thanks Ron, and all, for your insights.
