>Cmon guys y'all been in too much eggnog! :-)) Hi Gang, It's simple enough to check, isn't it? Not the eggnog saturation level, the cause of the problem. If the BR is rising and falling, the key height will be too. The dip will change, and the checking distance. Keybed bowing can be verified or ruled out with a straightedge, no? Perpetual head scratching over something too complicated to grasp, or requiring unavailable money, time, and instrumentation to measure, is understandable. In this case, however, wouldn't ten minutes time with a string and flashlight and a couple of standard issue brain cells explain a few things? Did anyone try that? No? If the keybed isn't bowing, did anyone measure it's thickness at the back edge to see if it's swelling? How about the overall height from key bottom to capstan top on one key to see if the measurement changed during the time between adjustments? No? Did anyone look at and measure anything at all other than dealing with the symptom of lost motion changing? Heck, I've cleared up more than a couple of really embarrassing mysteries for myself when I finally quit pondering helplessly and actually went looking for causes. It always makes me wonder what other painfully obvious things I'm baffled by on a daily basis. Hello, hello? Ron N
