Hi, While you will be at it, applying a drop of pure distilled water on the leather (if it is leather ) of the knuckle, can help you to tense it tight while gluing. The tension shows up when drying , and it is better not to overtight the leather first then (it is easy because the water makes it more soft). Then if you do that with little plastic press clamps and hot glue you can finish with a good job, assuming the underside is not too flat. Most of the KG series in France have Renner hammers, is yours ? - i've always been told that these hammers wher fitted by the importer, they used very heavy hammers, some pianos play like trucks, but at these times pianists seem to appreciate that (because of the teatchers instructions to gain muscles !).

Thought I'd report briefly on what I found. Jim Harvey and Vince Mrkalo get the prize for best diagnosis at a cyber- distance. I then tuned the piano, thinking over what I would propose to do. I ended up bidding a one to 1 1/2 day job, intending to ream and repin all hammerflanges (a hammer filing has to go along with this; fortunately the hammers aren't grooved very deeply); detach one end of each knuckle leather, stretch and re- glue, apply powdered teflon; do some other incidental friction removal, like brushing, ironing, applying powdered teflon to wipp cushions; polish and Mclube capstans; polish and mclube keypins; ease balance holes as needed. And then a fairly rapid regulation, including making damper lift a bit later. Slam dunk, I think. We'll see if they go for it.
