tight pinning

[Glenn]

Dampp Chaser will help it from coming back but it won't fix the tightness
now.  Try PURE methanol.  Must be PURE from a pharmacy supply.

I'm new at this but it was the subject of our last PTG meeting.  I believe
you can follow with Protek if needed.

Hello

So many messages in my mailbox

I have a Bösendorfer "Imperial" I will regulate and reconditonate the
action in 15 days.

This grand piano is in a very moisty place , something like 65%
permanent moist, and the pinning is very tight.

I suppose I will go for à complete re-pinning job, but they need the
piano for a show and I may do a partial job for the dec 15th, then do
the repinning, bushing, and so on , in january.

I never had much succes with the water-alcohol mixture, and anyway the
pinning seems really too tight 1 to 2 movements but no blocking hammer ,
basically all works, exept for real repetition speed.

Consider the piano will stay in this moisty place - is it correct to re
pin, or is there a better solution ? (the soundboard seems ok, too much
crown but it sounds 15 " of nice ringing on note #65)

I will appreciate an idea, something to help me for the regulation at
first. In my place there is 50% moist env.
If I dry the flanges, the pinning will free, but I will be papering a
lot, and it surely will not stay squared and free when it will be back.

Is it a job for Damp-ChaserMan ?...

Isaac,

Try the dampchaser idea.  Leave dehumidifier above the action for two days
or
so and see if it frees up your flanges.  If it does not work, try the
alcohol
and H20 or silicon and Naphta treatments as discussed in several of these
posts.
