This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Wim, No one can know for sure what is causing this without looking, but here are a few thoughts: - Backcheck height (already discussed) - Backcheck angle too far back (too steep of an angle) - Too much aftertouch for some reason - jack is binding on the rep lever window when key is held down - Action spread is wrong (which could be caused by parts not fitting on rails the same as old ones, etc.) causing too little jack clearance between the knuckle and the stop felt in the rep lever window. I agree with others that the backcheck angle / tail shape still seem to be the most likely culprits.

It isn't. I read Ed's post rather differently than you. I'm not as nice as Ed, so I'll go ahead and suggest that he was gently telling you that on those 3 notes you do not have tails with the proper radius and/or backchecks that are properly angled; if you did, they would work properly. This is a not an uncommon problem. You ask, "Why would one key/hammer work perfectly, and the next one, with all the same characteristics, not?" Obviously, they do not in reality have the same characteristics. Keep looking. Kent I've shaped the tails, rough them up, and eliminated the cutting edge at the bottom. I've adjusted the back checks up, down, in and out. Now what? Wim ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
