With normal I mean that Steinway has  Steinway specifications, weights and measures for every part and every regulation procedure like: Key dip - hammer alignment - hammer travel - hammer spacing -  let off - hammer drop - back check - springs - hammer blow - key frame, and all the numerous other things we have to do in order to make a beautiful touch and tone.</blockquote> grin... I beg to differ, but I would rather say that the instrument has need of a fine regulation... period. Slavically adhering to one or another manufacturers specs is in the end pointless. Fine regulation is achieved, also in the end by a complete understanding of how the various variables intereact to result in beautiful touch and tone. The fellow posting the query would seem to have more need for this basic understanding then he has for a bunch of theoretically correct numbers plomped in his lap.  Further it is not certain, due wear, ageing, and what kind of maintainance, or lack thereof that bonehard adherence to specs will work at all, or at least not at optimal. Indeed his question seems to point potentially in this direction as well. <blockquote TYPE=CITE>  Again, to obtain these data one should buy the Steinway manual. If one doesn 't, then it is like trying to drive a car without  driving lessons, usually resulting in a car accident and possibly a wreck.</blockquote> <blockquote TYPE=CITE>  Now to answer your specific question about Steinway key dip : on models S through B, key dip is set at 9,5 mm. On models C and D the key dip is 9.75 mm.</blockquote> 9,5 mm is 11/32 inch and 9.75 mm is 13/32 inch ( + or - next to nothing) and we are talking L model here. <blockquote TYPE=CITE>  friendly greetings,</blockquote> Hope you dont take offense Antares, I am not a purist, never have been and never will be. Did you ever get a chance to see the Horowitz grand. I have had the pleasure of viewing it and checking it out both before and after the Hamburg people ruined it. (That ought to provoke ya... grin) They attempted to restore it to Steinway Specs, and in the process removed any real connection this instrument had to the personality and style of that unbelievble talent. I understand that New York people are re-restoring it to Horowitz's preferences now. Key word there... preferences. Richard Brekne <blockquote TYPE=CITE>  Antares</blockquote> </body> </html>
