1. Check to see if the jacks are just slow but physically able to return without adding a lot of sloppy lost motion. Pinning, lubrication, may be required. 2. Are the jacks binding when the keys are "bottoming out"? Have bugs or mice gotten to the front rail punchings, i.e., too much (sounds silly for a spinet but ...) aftertouch? 3. Don't alter the checking unless you know that is the problem or they are not checking correctly now. But short-checking will screw up repetition and can even cause hammer blocking against the strings. My money would be on center-pin problems in hammers, butts, jacks, whippens .... bent, mislocated, too tight, corroded.

I would like to know your suggestions for cheating on regulation to improve the performance of a 1950s Baldwin drop action piano. The customer doesnt have the money for a full regulation. She complains of poor repetition and keys bottoming out without making a tone. Shorten the hammer blow for more lost motion? Alter the checking? Thanks for any tricks you can share.
