<HTML>Hey list! About 10 years ago I had the pleasure of attending Yamaha's "Little Red Scho= olhouse" session, where the small class was mentored by some of Yamaha's bes= t, including LaRoy Edwards who many of us have seen in workshops over the ye= ars as well.  Great program. If you can get a dealer to sponsor you it = is well worth the time! Anyway, the Yamaha method for bedding the key frame is simple and in my expe= rience works every time: Remove the stack so you can also remove the keys. T= ighten all screws in the bed, replace the stack (to "weight" the frame), and= put the frame back in the piano. Now set the glide bolts as you normally wo= uld. Remove the stack, replace the keys and Voila! the perfect key bedding. = After bedding this way, then you set the key height (also done with the acti= on in the piano and the stack on - very slick). Finally the dip is set later= in the process when it can be done on each key individually taking into acc= ount the proper distance as well as the correct or desired feel of the after= touch. will</HTML>
