[CAUT] moving capstans question

[Paul T Williams]

Hi List!

Happy Friday!

I am working on a 70's Sty B with a horrible action geometry problem. All 
the students and the professor hate playing it and I don't blame them! The 
line from key balance hole to wip has the capstan way too low making the 
DW close to 70g throughout.  It has a renner action and hammers.  the wips 
and capstans are such that I could relocate the capstans back by about 
3-4mm.  Would that make a big enough difference in the DW? It won't affect 
the line.  I looked at raising the stack, but there isn't enough room to 
raise it more than 1-2mm.  Should I try both?

Also, is the measurement in Steinways made from center of balance rail 
hole on the top of the key, or from the back of the key?  This is a new 
endeavor for me and I don't want to make things worse.

Still green in Lincoln,

Paul
