<HTML><HTML>Greetings list,             &nbs= p;    I am doing my very first grand regulation. After carefu= lly measuring the felt punchings thickness, I ordered new ones and replaced = both front and balance rail felt punchings because they were shot. I also re= placed keytops. The new keytops were .03 thicker than the old ones. I knew f= rom the beginning I would have to compensate in the regulation for the new k= ey heights, and probably some of the residual miscellaneous felt height as w= ell.             &nbs= p;    At the job site I put lead weights on the keys' backs a= nd levelled the white keys and then set the key dips on the whites as well. = Then, because I am green at this, I removed the the keyframe from it's bed a= nd replaced the stack, screwed it down and when I slid it back in, the keys = were all different heights(!) What went wrong? Are the keys supppose to do t= his. Are my weights too heavy? Must I consider keyweight when leveling keys?= rookie, Julia Gottchall, Reading, PA </HTML>
