Clarify: "Dollies"? Do you mean key capstans? Whatever the case try a little heat from the tip of a soldering gun, that will often free parts that have seized in wood. If not try heating, cooling, and heating again. The repeated expansion may break it free. That almost always works for let-off screws. Once you get the screws moving I'd go ahead and pull them out and replace them. It's easy to do and their cheap.

I have turned a few of them but they are snapping. I have reshaped the hammers and am having the same problem adjusting the let off, the metal parts are just shearing. ....any suggestions? -------------- next part -------------- An HTML attachment was scrubbed...
