---------------------- multipart/alternative attachment Hi Dave, I agree completely. Sequence is every thing in quality damper work. Changing lift tray felt, and key end felt, can save a lot of time and hassles in the long run, on a well worn action. The Spurlock jig makes timing a snap. As a tip, Iron new felt with a warm clothes iron before installation, you will be amazed how few keys you will have to shim. just my 2c worth Roger At 06:19 PM 6/8/02 -0700, you wrote: >The only problem with this method is that it sets the timing for the pedal >sometimes at the expense of the keys and the sostenuto.
