Working on a la Tosca unit. 15 3/4” keyboard. The frame has nice rounded bottom edges…but….over the decades, the two outside keys have warped to the outside and are binding against the frame. Two places to address…first is the rod going up to the pallet. Make sure the rod is not making contact with the wood frame. when the unit was made there was just a little bit of clearance chiseled out for the rod to freely move. You can take a small veining chisel and get behind the rod just enough to clear out some extra wood if needed. Next is the corner of the key at the rounded edge of the frame. Take a piece of 100 grit sanding belt and start sanding down in the lower edge of the key. The smooth back but strong sanding belt piece will let you push the paper down without bending the paper. Flip the paper over and sand some on the frame also. Just be careful and don’t sand any on the upper part of the key. Sanding marks on the lower side won’t be noticeable. You can finish up with some 220-600 grit if needed. Both keys on this unit work fine now. No telling how long this accordion sat unplayed just needing these sticking keys repaired.
