<html> <body> Patrick, Don't be afraid of anything breaking.  Just bend the thing.  Start small, springing the keyslip a little, gradually increase the force until it takes a set and stays where you want it. I have adjusted many of these, and not one has ever cracked.  I'm sure it could be cracked if one where really aggressive and tried to bend the thing out dramatically, but all that is needed is a slight change - a few millimeters at the center.  Just bend it - that's why it is made that way!

I expected that it was the absolute neglect of action regulation on her part (which when I remind her of the need to do some work, she says "I'm not going to put any money into this piano; I'm going to sell it and get a really good piano" -- she's been saying this for more than 10 years). Turns out it was just the keyslip binding on some keys. Now, the dramatic fix that is usually demonstrated in Kawai classes has been taking the keyslip out, putting on end on the floor, the other on a bench, and putting one's foot and a good part of one's weight on the midpoint (inside surface of course), bending it from concave to straight. I remember Jim Harvey doing this with a big smile on his face. Somehow it's difficult to pull this off in front of the customer. Especially when you know that if something nasty happened (CRACK!) to a Kawai tech like Jim or Don Mannino, they would look so much more self assured than I, as they intoned ("Hmm, this part doesn't seem to be up to standard specs -- I'll have another Fedexed out tomorrow ..."), rather that (me: "OMIGAWD!"). So -- are you all wildly successful with the Controlled Stomp Technique? My attempts at the whimpy version (one end on the rug, and pushing hard with one hand) seems rather futile. This time around I shimmed behind the "shims" (I can't find a proper name for 'em in Mason's <Piano Parts> -- quick Tom D, what's the name?) that are attached to the back of the keyslip and are clamped down by the cheekblocks. I don't recall this ever being suggested as a "proper repair." With proper clearance achieved, I could  head home & try to enjoy my Saturday .... So: what is the Correct Fix?
