  William et al, During this discussion, even tho it should be apparent, 
the first thing needed to do is get the action parts to correct 
functioning specs....i.e. Recondition the Action. This entails making 
sure ALL of the center pins are at proper resistance. Resistance is 
necessary to achieve SOFT playing.<G> Proper Hammer surfaces, that are 
MATED to the strings, is another biggy, imo. AND, the keys need to be up 
to specs. No loosy-goosy key bushings. No excessive friction in the 
piano is also a biggy. Worn Wippen Foot Felt is a usual place for that 
sort of thing. In the case, that this is an upright, the butt 
leather/felt needs to be 'pock' free. Damper lever lift felt can be a 
problem. The list is almost endless. However if care is taken with the 
Mechanical problems, the Regulation problems are, usually, easy to 
solve. That's my take on it. Joe Joe Garrett, R.P.T. Captain of the Tool

Joe,

You're absolutely correct!  Like it says on page 6  of the 'G' Piano 
Works Repair Labor Guide under "Major Regulation: Complete", "All 
repairs & maintenance necessary to accomplish a FINE REGULATION must be 
done".
