Do you ever have any trouble with the front being chipped by the router =
bit?

  For planing the tops, a plunge router bit in a drill press works well. =
The key is held in

notch produces
  a nice onlay to the key with the plastic.

  Trimming can be done with a flush router bit and jig ala Bill =
Spurlock. I prefer to trim by
  hand with a file.

  Clamping is not necessary when you use PVC-E glue.

  Pianotech has a nice keytop, I like the off white.
