This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hello, I'm a professional pianist and I own a Bechstein grand piano model B = (203 cm) dating 1988 (one of the last with ivory keys). I have a = question about proper bedding procedure for this piano. The main concern is about bedding it with keys and action installed or = without them using the paper method under the bolts. In the first case should I tighten the cheeks screws? And in what order = should I regulate the bolts? Should the keyframe of this piano be considered rigid or flexible? The 2 procedures give very different results, expecially in the middle = registers. What bothers me a lot is checking key height after bedding. = It should be 63 mm (that's what Bechstein told me), and this is correct = on the left and right side, but if I do the bedding with action and keys = installed I obtain a much lower key height in correspondance of the 3 = middle bolts. Could the keyframe have bended in the balance rail over = time (in case it is a rigid kind)? Is a bedding procedure based exclusively on "sound quality" be imagined? I notice a lack of power/precision with the (lighter) bedding done with = action and keys installed. Also playing gives a feeling of keys sticking = to fingers. How does a correct key height influence sound quality and pianist = feeling? I would greatly appreciate any help coming from those with experience on = Bechstein grands. Thank you very much, Roberto Rega (Geneva - Switzerland) ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
