[pianotech] Tuning Pin Replacement AFTER CA Glue

[Paul McCloud]

Why not just ream  the holes and then repin?   You might try pounding the
high pins in and see if they get better.  I wouldn’t dismiss the CA option
out of hand either.  I once tried it, and it didn’t work at all.  In fact I
tried several times.   Turns out I was using the wrong glue (from Home
Depot).  It has to be the super thin variety which isn’t sold there.  There
are many on this list who have had very good and lasting results using CA.  

Interesting that your Baldwin pinblock is too loose.  Baldwin is known for
its very tight pins.  It might suggest that once the block lets go, there’s
not much that can be done long-term without replacement.  

My two cents.

I would appreciate any advice anyone might be able to offer me regarding
replacing the tuning pins in a 1961 Baldwin L with, I believe, a replacement
pinblock that was subsequently treated with CA glue.  Will the old CA glue
cause any problems when pounding in new pins.  I think one size larger would
yield adequate torque.

The piano is in a school, and was “rebuilt” at some point in the past.  It
has “new-ish” hammers, shanks, flanges, a shimmed and refinished soundboard,
possibly recapped bridge, new-ish bass strings (still shiny).  Fundamentally
a nice piano.  It appears a new block was installed, and the piano
definitely has been restrung.  Unfortunately, the tuning pins were left
waaaaay too far out of the block, and most are flagpoling.  Some sections
were pounded down (later, I assume, by someone else?), but must be this
failed to provide adequate torque, so CA glue was used on some pins (visual
evidence, feel).

Excessive dryness from HVAC has been a chronic problem in this facility
since it opened in 1961.  I have a new Life Saver System I will be
installing.

Why re-pin?  Because I’m not a fan of pinblock restorer or CA glue.  So to
get the torque up I am thinking of trying a full re-pinning.  There’s no
money for another rebuild or move to shop, so I am trying to make this piano
serviceable where it is in the band and small group rehearsal room
(currently in use there).  With tuning stability, it’s parts indicate it
could be well-regulated and voiced, becoming a very clean, respectable
rehearsal room piano (6’1”).

Thanks for the help.
