Hi, a typical original Bechstein back rail is not one piece of felt but four or five strips (pail blue nameboard type of felt if you want to be original) about 1/2" wide covered with a wider 1 1/2" width so giving a overall height of about 4 mm. Balance rail felt is also thin with a few paper washers and front touch washers are also around 4mm. No glides on a Bechstein but check bedding of keyframe for unusual warpage (warp factor 9 or above is too much captain!) I usually set key height to about 18mm but in the end it depends what works Brian ----- Original Message ----- From: "Breakall, Raymond" <rbreakal@richmond.edu> To: <Pianotech@ptg.org> Sent: Friday, July 19, 2002 2:42 PM Subject: Bechstein key height Dear list, I am trying to fiqure out key heighth for a Bechstein grand. I must jack up the the back rail felt to fit properly with the keyslip. Then I find I don't have enough movement in the key to get enough key dip. Any ideas?
