The Piano Action Handbook by Randy Potter lists specs for most Steinway grands, except the A. But, they are all the same - so perhaps the model A will be the same also - likely a good starting point anyway. Key Height: 2-19/32" to 2-5/8" Sharp Height: key behind sharp should be 1/32" higher than adjacent natural key. Hammer Blow: 1-3/4" (except model D is 1-7/8") Hammer Let-Off: 1/16" Key Dip: 0.390" (may be up to 0.420") Back Check Distance: as high as possible, a bit lower in bass Drop: Let-off plus 1/16" maximum, tighter if possible ----- Original Message ----- From: "james turner" <JTTUNER@webtv.net> To: <pianotech@ptg.org> Sent: Tuesday, September 18, 2001 4:06 PM Subject: Re: pianotech-digest V2001 #1247 > Can someone recommended the "suggested" key height and height height for > a l940 Steinway A piano?
