[pianotech] Key leveling

[David Skolnik]

Regarding the reverse thread tuning pins and 
technique for creating gap between coils and 
plate, I guess its success would depend upon the 
thread rate and angle.  The rate at which the pin 
elevates from block compared to wire diameter 
being replenished at bottom of coil.  And, as for 
keydip screws, I am most curious to see this 
mechanism that allows control of .003" or less increments.
