It does seem like a cheap method (not necessarily a bad thing), but I'm wondering just what did cause it to go badly out of regulation. Isn't plywood pretty inert? Was the keybed substitute too thin? Or the tubing too flimsy? Or the whole thing just poorly constructed? We do need to be open to new ways of building pianos that save money without loss of performance.

Here is the substitute for the traditional keybed and keyframe. Balance and touch rails are glued to a sheet of plywood which is bolted to a tubular metal frame. The backtouch felt is glued directly to the tubular frame . This particular piano had to be replaced by the retailer because the regulation went completely haywire over the winter! I wonder why? -------------- next part -------------- An HTML attachment was scrubbed...
