Hey Avery! How can you do prep-work regulation on an action that's away from the piano??? Try this; At each end of a section... before removing the action from the piano. Regulate each note at the extreme ends of each section for let-off & drop. Being sure you have rep-spring tension at least equal to the task. Be REAL finicky about it. Use 1/16th" for each. (Don't argue! Just do it!...) When you get back to the shop; Set the action on your work-surface and haul out that ol' wooden regulating jig... the one with the adjustable strike-surface you can hang over the hammerline ( a thin piece of wood held by two screws onto a board suspended by two adjustable wing-nuts tensioned by a coiled spring... or ...whatever you happen to have). Adjust the jig to get the proper let-off & drop from your "samples" for a section and measure the height from your work-surface to the "strike-point" on each end of the jig by the samples. Write these numbers on a piece of paper (...do not lose, misplacing is OK... but do NOT lose this!). Voila! You can now duplicate the "string-height" for that action no matter what you do to it in the shop. Somehow, it seems that measuring the string height from the bottom of the action-housing or keybed (...depends on where you went to school... I guess...) never seems to produce the same results in the shop for me. Basic regulation done from tape-measured string-height or measurements from string-height guages never seem to produce the same results. << Mebbe the idea reduces the measurement and jig adjustment to it's smallest denominator; Here's the jig. Here's where the samples work on my bench in my shop. Measure the jig height. Period. >> Doing it this way gives you repeatable results for that action even if you completely replace the hammers & flanges or all the keyfelts... or whatever screws up your regulation. Whaddaya think? Will doin' this thang he'p ya? Works fer me. Uh-huh, Jeffrey T.Hickey, RPT ps- The Yamaha folks blew the call to the tech on the key-replacement. Whether this was the Corp., the dealer, or the tech who was sent is the question. I agree that the tech should NOT have serviced other pianos in the home, a rude move (...without even a call!). We don't know what happened, (...as WE weren't there!) but my sympathy is with the tech who got cold-shouldered. A letter or call to the local Yamaha rep would probably net a sincere apology, 'though. This company really does listen to the techs out there, and they do seem to care about "Doing the right thing.". I wish all companies had that attitude!!!
