[pianotech] Bridge Pin Drilling Angle

[David Love]

What's the difference between leaning the pin out a bit and just cutting the
notch just back of pin center?

I've always heard the explanation Frank offers for that 
outward lean, and it always seemed reasonable. But when you 
really look at it, the offset angle would be bisected by the 
pins leaning back over the bridge instead of out and away from 
it. Wouldn't it?
