This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment If the action is all the way in against the dags you can slide a screwdriver under the front of the action frame and pry up. This will effectively move the strike point further in giving you just a little more adjustment for trials. When listening at the breaks you are not listening for a "sweet spot" like you hear on C88. What I hear are some trashy upper harmonics that get better, almost like a voicing problem. There will actually be two spots where it gets better. Pick the first one. It takes a pretty hard hammer. The rebuilder I know who showed me this technique has hammers specifically for adjusting the strike line.

The top two treble sections are where the concerns lie. Tack-glue a hammer on a shank using the originals for guide at the ends of each section and maybe one in the middle of the first section (killer octave). Place pieces of masking tape on the key bed at these trial hammers. (Have the tape go under the key frame). Install the action and cheek blocks. Draw a line on the tape at the edge of the key frame (sharp pencil). With the treble block removed, play the note while moving the treble end of the action slowly front to back. If the tone is better with the action relocated, place a line on the tape. Do this for each trial hammer. (This assumes the action was situated properly to begin with). The difference between the lines is the amount in which to relocate your trials. Relocate trials, verify. Don't be shocked if there is a curve to the strike line. Glue on the other hammers to these trial guides. -- Regards, Jon Page ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
