Ah, another mystery. Keep in mind that noises travel a bit in the keybed itself, so sometimes the location is misleading. - Check for a loose balance rail glide bolt - Tighten action stack screws - Check keyframe glue joints on the right side of the action. I have had this kind of noise with glue joints which have become loose. - Remove, lube / rebush (if needed) una corda lever pivots. Check for rubbing or interference. - Remove spring and check for something fallen behind it. Make sure screws tighten well when it's put back. - Look at keyframe where una corda is pushing on it. Check for split /chipped wood or other damage. - McLube 444 on top of una corda lever, side of keyframe, and on return spring.

It makes a "click" or something like it when pushing the pedal down. It is minimal when pushing quickly, but is very noticable on a slow push. It's also even more noticable on pushing and releasing the pedal. I sanded and lubed the right side of the key-frame, and also polished the return spring, but it only went away slightly. It sounds like that is where the sound is occurring. The lyre action is not where it's happening, so where might I look next?
