Warp is such that at the right hand corner (by hinge) is about half an inch up when lid "closed". This happened some time ago when I believe owner had it in storage somewhere. It is figured walnut and weighting cost of feasable repair against replacement. I had thoughts of pvc go bars as recently described except workshop has very high ceiling and not sure how much pressure for how long if this is an option. Thoughts, suggestions, comments welcome. >> Putting pressure on the lid to make it flat, if the lid is laying on a flat surface will not take out the warp. You will actually have to over bend it past level, to get it to straighten out. If you are going to have the piano in the shop, put the lid on the ground, but put most of it on 2x4s, so that the warped part is hanging free. Put a large heavy object, like a garbage can with water in it, on the warped end, and let the weight push it down. Check frequently to see the process. Caution. Do not put a damp cloth or add water to the lid. because that will effect the veneer of the lid, and you'll wind up with a different problem. Good luck Willem
