[pianotech] pin block inserts

[Gary Telleen]

Dean,

Jim Coleman Jr. made a video several years ago specifically on pinblock
inserts.  You can find the video for sale on Jim Coleman Sr's website

<http://www.pianotapes.com/www.pianotapes.com/>I don't think Jim Jr. is
subscribed to this forum, you can contact him at jcolem21 at utk.edu.  He has
been doing block inserts for well over 20 years.
