I would first remove one plate screw and see if you can go a size up...I don't know why you couldn't cut strips of leather as we've been talking about and CAing them into the hole and then turning the screw back in.

Hello,
Came across a 1920’s grand whose brass pedal rods are corroded where they enter the wooden pedal box.  They are frozen and won’t move.  After pointing out the corrosion to the owners, they THEN tell me that many years ago there was a dog that would urinate on the pedal box.  Uh?  Yeah!  That would probably corrode them.
Any advice on how to “unfreeze” them?  I already told them that I would have to take the whole pedal mechanism/ Lyre off and polish the rods back at the shop.  I am not going to do the job in their home.
Also, came across a Chickering baby grand, fairly new, and there are 3 front plate screws, right in the middle of the piano,  that appear to be stripped..they just spin around and don’t grab any wood.  How can this be fixed?  I imagine that it can contribute to a lack of stability in the instrument.
Thank you folks,
