Repair and Tuning of Estey Baby Grand

[Andrew and Rebeca Anderson]

Robert,
You start by looking for foreign objects or substances or broken 
parts.  Eliminating that you move on to friction 
concerns.  Front-rail key-pin friction (rust on pin?), center-rail 
pin friction, does the key return to its upright position?
I've been living with an imported Chinese grand on my floor, a rather 
rough jewel.  There was lots of key easing to do.  Eventually after 
that there were two that started to not come up, hammer flange 
friction turned out to be the culprit, ream & re-pin.

When I started in Piano Technology I lived far away from the nearest 
PTG chapter, four hours over three snowy mountain passes.  I missed 
out on a lot.  If there is an active chapter meeting regularly within 
reasonable distance, join.  The Randy Potter course is probably the 
most comprehensive correspondence course available.

Good Luck,
Andrew
