[pianotech] open letter to CA users..???

[Rob McCall]

The client had the budget for a repinning but not a restringing. All the pins are out now.  About 75% of them came out okay with minimal effort. The other 25% ended up getting cut close to the becket as possible, and then recoiled with a new becket.  The pinblock seemed in good shape. I checked the pinblock as thoroughly as possible and I didn't see any apparent issues with it. 

It's in a 1983 Sherman Clay SDG2.  The new pins are going in today and they are holding nicely. The bass section is pretty much done and all new pins are tight in the pinblock. It just took a lot longer than I was expecting to get the old pins out.

I didn't realize there was a previous CA treatment until I started backing out the pins, and I do have a nice drill to do that, at least...  :-)

I don't know that more CA would've worked.  Most of the bass section wasn't just loose -- the tuning pin would not hold even the slightest tuning. It took about 60° of turn to bring it to pitch, and then when you let go it would unwind right back to where it started. It seemed way too loose for me for CA, but then my experience is limited on the edge of the envelope stuff for CA. Is there a limit on just how loose a pin can be and still accept a CA treatment?
