I am working on a project of transferring a collection of 16" lacquers, a number of which have suffered water or humidity damage, due to poor storage conditions.
One of them is a glass base disc of the Koussevitzky 2/27/1943 world premiere broadcast of the Roy Harris Symphony #5. One side of the disc is playable; the other side is delaminating. A portion of the lacquer has started to peel off, but is still attached. I have had some success with re-affixing peeling lacquer in the past, but unfortunately, differential shrinkage has set in, and the partially peeled off section does not quite align with the unpeeled section. The method of re-attaching the peel is temporary and not strong, and I would appreciate any hints on a permanent method.
While I can readily deal with the clicks and clunks this will cause, I am reluctant to try to play the side, as the normal rotation of the disc and stylus would "go against the grain" of the peel, and the stylus would try to lift the peel off the glass. I would probably have a greater chance of success in playing this side if I could play the disc while it is rotated counter-clockwise, and at 16 2/3 rpm.
Has anyone here ever done this? Of course, the arm will have to be re-mounted, and there will be a problem with the offset geometry, but I'm willing to suffer the tracking angle distortion if I can play this disc. I do have an aircheck of this performance, but the sound on this disc is rather better, and without the severe pitch problems of the aircheck.
Any advice would be greatly appreciated. Thanks!
