pin tightner

[Z! Reinhardt]

Hi Don!

Thanks for your insights about this matter.  It could hardly have come at a
better time -- just today I met an upright piano whose pinblock had been
doped (Pin-Tite) over the summer by another technician and there are still
plenty of pins that are not holding.

Now I'm wondering ... will oversized pins (I have some Larudee Lo-Torque
pins, sometimes known as fat-bottom pins) help with the pinblock already
treated, or should I go straight for the CA and hope that I won't be
breaking overly tight pins when I try to tune it?

P S - Rode the train to/from Reno from Detroit and had a great time.
Already have my train ticket to Boston for the Holidays.

Hi,

In regards to adding CA to already "traditionally" treated blocks. Use
LESS. The CA works even better when the block is already full of ethylene
glycol. Pins can become so tight they will shear off. If you have over done
it, tap the pin(s) with a hammer to "break" the initial glue bond.

P.S. ridden any trains lately diskladame?
