<HTML> <BODY BGCOLOR="#FFFFFF"> Yes indeed, 15 mm is far too much. If you change dip that much to correct it you must readjust checking. If the aftertouch is really OK with 15mm dip then you must have a whopping amount of blow distance, and it should be reduced first, then you will find far too much aftertouch. If the blow is corrected, you will be able to reduce the key dip and be left with good aftertouch. They are interrelated, it is unavoidable. Sounds like a full regulation to me. Sometimes we run across a previous technicians work where a few things were adjusted and look great, but fundamental elements of the regulation were skipped over. If the foundation is bad everything that follows has to be redone. There is a reason for the order of steps in regulation.                                                                     Cheers                                                                     Dave Renaud                                                                      RPT                                                                      Canada Brian Holden wrote: <BLOCKQUOTE TYPE=CITE> My customer has a good old Carl Ecke piano and is complaining that the keys feel sloppy, yet the bushings are O.K.  The key dip I discovered, is a whopping 15mm, with the sharps disappearing below the whites when fully depressed.  The H to S distance is the normal 45mm so the ratio is all to billy-o.  Any suggestions as to how I can reduce the dip but retain the checking and aftertouch which are presently both good.  This is probably a fairly basic regulation problem, but I thought it would be a good opportunity to put the Forum to the test.  Brian Holden</BLOCKQUOTE>   </BODY> </HTML>
