[pianotech] those pesky tuning pin bushings

To clarify something Ron N. said in passing:

The bushings come in at least two sizes of outer diameter, and the plate webbing hole diameters vary from piano to piano. The bushings should be a tight fit in the plate holes.

  Hello list,
  Does anyone have a technique to prevent most of the tuning pin bushings from splitting?
  I drilled the block outside of the piano, not a thought about bushings.
  The way that I string, I coil the string round the pin and punch it into the hole with the bushing in place.
  Splits every time.
  The bushing hole diameters are all .250 but the 2.0 tuning pin is oversize by .031
  Drilling the bushings to match the tuning pins is tedious and still about 50% will split.
  What am I missing?
  Thanks for any help.
  Gene
