CA pinblock tightening

[Don]

Hi Tim.

Inspect the piano and look at the bridges--if they have hairline cracks
take along some thick CA glue and apply it to stop the cracks from becoming
worse. 

Use super thin (runs like water). Get it from a hobby shop in an 8 oz.
bottle. Tip piano on back. Apply CA glue (lots). Leave piano on it's back
for one week. Tip piano up. Begin to tune. If you find an *exceptionally*
tight pin use a tuning pin punch and hammer to drive the pin and break the
glue joint. CA glue *can* make the pin so tight it will shear off (blush).
This may be more important if the piano has been previously doped, if the
piano has #1 pins, or if the pins are a bit rusty.

Some people recommend driving right after application. I prefer not to and
have had good results--this also leaves room for the breaking of the glue
bond. Best of Luck!
