Tuning ten times the number of pianos outside of universities than inside, I find ten times the loose screws inside than out. I'm not entirely sure what that means, but there it is. Being a contract tech, rather than official inventory, I only see the pianos a couple of times a year. By then, one or the other music desk hinges is no longer loose - it's detached or missing altogether, and the other is torn apart by the daily clever attempts to get it to support fifteen pounds of whatever all by it's lonesome. I'm getting pretty good at hinge blacksmithing in practice rooms using just the tools in my case. You know - forge, anvil, etc. I take a(nother) lyre back tomorrow, that was bifurcated by the clever moving techniques of whatever portion of the maintenance staff happened to be available for the last move. It's an S&S B, and yet another lyre stick incidentally evaporated in the process. I'm beginning to think it's time to tool up to make these things, since I'm running out of old beat-up salvage replacements. It doesn't look that tough. Ron N
