Lubrication for Verticals

[Giovanni Voltaggio]

Greetings List -

There's a Petrof 115 that I work on, about 12 years old, and the  
action is sluggish.  Repetition is bad, it feels like the friction  
happens in the bottom of the keys, even in the upper section with no  
dampers.  Regulation is good although maybe the capstans could be  
backed down very slightly.  I don't think the action centers are tight.

I'm thinking I can clean the hammer butts and lubricate them and the  
top of the jacks, I guess I can use a spray on teflon dry lube for that.

Next, I'll want to clean and shine the keypins.  Any ideas?

thanks,
Giovanni
