<<>I hate it when I regulate a piano and it is WAY out when I get back to the piano. >> Greetings, One way to avoid this is to set your keydip on the ends of the sections, in the piano. When placed on a bench, shimming to restore this same keydip will usually make that section very close to its final specs. It is faster to do some things in the piano, like let-off.
