removing key pins

[Elian Degen J.]

I would like to hear more about this statement, as my experience in the
field has been exactly the opposite.
Holes did get larger as wood dries out. and I can mention it happening in
many instances, I use a drying chamber for many of my jobs because of that.

examples.

When I pick up pianos for repair from very humid places. after I had them
several days in my shop

All action screws loosen up, they need tightening
Tuning pins feel looser, after the piano is back in place, you can feel the
difference after a few days
and I observed the same pattern with the key pins

So, I would like to hear an explanation to this statement.

tuning pins get more loose with lower humidity?
