This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I guess I should have been more specific. This is a 1933 grand action = with no drop screw. I found that with too much spring tension let-off = does not "feel" right and the hammer will bubble. (makes sense). Let off = adjustment is done with the action removed. I guess my question is how = much spring tension is right to get the proper repetetion? I have it = playing fairly well as all the other procedures are about the same.My = research showed this action was discontinued in the 70's or 80's. Thanks.
