Pinblock Drilling Centering

[Alan R. Barnard]

Why not go ahead and install bushings if there is room? I'd like to see how
a bushed Steinway would tune. As they say in Brooklyn, "It couldn't hoit,
could it?"

> Ron N's recent post on the bad rebuild reminded me to ask the following.
When drilling tuning pin holes in new block in a full plate with no plate
bushings, how best to center pin? I see so many that have the pins riding on
the plate, just as many were on my one of my current projects. Would it not
be best to just kiss the forward side (closest to pianist) of the plate hole
with the drill bit (it will be going in on a bit of an angle, of course).
That way when strings are brought up to tension, the pin will move slightly
(yes?) off the plate edge, and end up somewhere near the middle of the hole
(yes?). I have never done one of these before, but I fear that if you drill
the hole in the middle of the plate hole you will end up with the tuning pin
riding the plate on the rear side of the hole.
