[pianotech] those pesky tuning pin bushings

[Dean May]

I don't recall that happening when I've done it, but I only had to do it a
couple of times. I wonder if a drop of CA glue after pin insertion would
freeze the bushings to prevent splitting. I don't see how it could hurt.

Gene,
I've seen the water tried, and it works great - until it 
evaporates after the pins are in. Then the bushings split anyway.
