With the amazing amount of tooling that Yamaha and Kawai have, I think it would be a simple matter to drill and insert wooden plugs where screws are installed. Lacking this, us field technicians could make a rubbing of screw hole patterns (one edge of paper taped down to maintain registration) and then holes similarly drilled and plugged (side grain maple cut with plug cutter). Time-consuming, yes, but if you don't have time to do it right the first time, how are you going to find time to do it right the second time? -- Thomas A. Cole RPT Santa Cruz, CA
