Mason & Hamlin Screwstringer

I guess it was bound to happen sooner or later (in this case later!), an 
1890 screwstringer upright. The owner dearly loves the tone, in spite of 
its original condition, and it just needs to be tuned. Never having 
accomplished such a feat, I was at a loss to tune or stabilize the 
tuning, in spite of the instructions on the tuning key holder (Tuning is 
accomplished by approaching from below, and Whanging on the key makes it 
go sharp - words to that effect).

The strings weren't especially rusty, just a little dark. I applied 
Liquid Wrench to the bearing points, dropped the pitch and brought it 
above pitch to gain some lubricity but, alas, not much help. After 1-1/2 
hours of twisting and whanging, I got about an octave's worth to sound 
like they needed to be tuned.

Reminds me of an old Studebaker I drove once that had a huge amount of 
play in the steering gear. It was uncontrollable. Is there any way to 
tune this thing? I thought of reducing the offset at the "V" bar by 
backing off on the pressure bar screws to reduce friction. But how much? 
Is that advisable?
