Thanks to everyone for your suggestions on how to solve my key rebushing nightmare, the original post was entitled "disrupted mortises". They were disrupted when I removed the bushings that were glued in with PVC-E- alot of wood came out with the felt. Though were many great suggestions as to how to get an even rebushing job at this point, here's what I did with some success... I essentially did a 'trial and error' rebushing job. I felt-tested every mortise individually with different size felts. In the end I used a wide range of felt, spanning as many as 5 sizes apart. Each key got whatever size felt that gave me the snug fit that I was looking for. Though this procecdure took a lot longer than a normal rebushing job, I am pleased with the results. I have not decided whether to charge the client more for the job, since it took much longer. What do you all think? I dont really feel comfortable doing that. I guess my feeling is that, some jobs you make out on, and some you don't.
