Yep, wire-bending problems. A real caveat when estimating time is to wonder who worked on the instrument before, and how much and what sort of wire- bending was done. The trouble (and, in a sense, the beauty) with the action of most/many celestas is that you can solve just about any problem by bending a wire. That's great for tweaking things, but if carried to extremes, you can find a real mess on your hands. Bending the "hammershank" wire will adjust "hammerblow" and "let-off" (how close the hammer gets to the tone bar before the key is stopped by the front rail punching). So will bending the "drop-sticker" wire. And bending the damper wire will improve damping (if done properly) but will also affect hammerblow (on at least some designs). If someone has been bending wires all over the place to solve every sort of problem, you might have a lot of work unbending before you get to the point of being able to regulate (understanding that bending per se isn't evil - it's more or less the final touch in fine regulation if you get that far). > Mustel and > Schiedmeyer are more technician-friendly. I haven't worked on Schiedmeyer, but agree that Mustel is a nice design. Though that opinion is based on memory that is growing hazy. I managed to get the music department here to spring for me to work on the department's Mustel for a couple days about 15 years ago. I did a fairly comprehensive job: bushed keys, replaced keybed felts, levelled and dipped. Re-bushed tone bars (they were the type that are held in place by two screws, and the rubber bushings had disintegrated so they were buzzing up a storm). And then a fairly thorough regulation from scratch. Memory says two full days, but it could have been three. The results were pretty good, I thought. But then the instrument up and disappeared. Walked without a trace. Damn! > > I especially agree with Fred on the time, maybe even more, if this is > your > first one.
