This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Thanks Del, I was wondering what you use for string height and let off = gauges. I was thinking of an over head rail that could be marked with = string locations as well as being adjustable to different string = heights.

It was set up if I remember so that you could pretty = faithfully re-create the key bed and get really good bench regulating = results.=20 Maybe Del can say something about this, or even perhaps provide us = with a picture of said. ??=20 =20 I've used two benches set up for regulating. One was based on a 1-1/2" = maple slab, thickness-planed a dead flat as I could get it. Cross-grain = slip-ribs were used across the bottom to keep it flat. The bench I use = now is based on a maple/alder laminate with a heavy maple rim. The top = surface has a thick layer of epoxy. The edges were built up about two or = three mm above the bench surface and epoxy flowed in and leveled out. = The bottom surface is also epoxy coated. It's flat and stable. Along the = front edge are Steinway style center-rail keyframe bedding screws on 200 = mm centers adjustable from the bottom. =20 The action is bedded in the piano and key dip set as accurately as = possible. The action is transferred to the bench and the bench bedding = screws are adjusted up to duplicate the keydip specification on the = bench. Most keyframes will set up this way. Occasionally there is one in = which the keydip will be shallow on the bench in which case a 1 mm = veneer is placed under the balance rail.=20 It's not perfect but it's close and I'm past the point of wanting to = do all my regulating in the piano.=20 Del ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
