lost motion changing

Hello list,

I recently regulated a very old upright...about 70 yrs old or so.  I
went back today to check the tuning as per client's request.  Tuning was
really ok, but a few unison's were out. 'Course the humidity is way up
today and temps are in the 80's and all the windows were opened. But,
she's a nice lady so to tweaked the unisons.No big deal.

However, I noticed lots of lost motion everywhere. Can't figure out why.
The capstans are quite loose and perhaps they worked themselves down.
But the client is a beginer and uses the center of the piano. There was
lost motion everywhere. I adjusted the lost motion in the middle third
of the piano and will check it again soon to see if it changes. (didn't
have time to adjust the whole piano)

Any ideals what could have happened?  This has never happened before. 
Is there any way to tighten up the capstans? (I can hear it now..."CA
glue, Frank!") 

This is so strange.
