Pinblock for Baldwin SF-10

[Delwin D Fandrich]

Baldwin does not use Delignit pinblocks. They use their own version of a
material know elsewhere as "ComPreg," or compressed-impregnated wood. It's a
take-off on a material that worked very well for engine mounts in WW II
minesweeper boats. Its value as pinblock material is debatable. (If you're
interested do a search of the archives--I've written about this stuff in the
past.)
 
Use Delignit if you want; it will certainly be an improvement. Or else simply
use a plain old multiply maple block. This also will be a big improvement.

Subject: Pinblock for Baldwin SF-10


I am installing a new pinblock in a Baldwin SF-10. This piano is only 10 years
old, but the pinblock has been destroyed by the use of metal tuning pin sleeves
in combination with CA glue (about 30 to 40 sleeves and glue all over the
place). I can't imagine a 10 YO piano with what appears to be a Delignit
pinblock get so loose that it required this kind of desperate repairs.
 
My question to the other rebuilders is this. I have always used Bolduc pinblocks
in Steinways and Masons and have used Multi-Laminate pinblocks in lesser pianos,
(never had loose tuning pins in 40 years), but I have never used a Delignit
pinblock. Should I replace this pinblock with the Delignit (which now scares me)
or one of the others? Also any thoughts on what might have gone wrong with this
piano?
 
Thanks for any input
