Over the years, the cardboard installed for adjustment disappears (is removed), and other things must be done. After turning the pin to a less worn position, and occasionally replacing the plate in the key block (if it is particularly worn), I have always removed the dowels (cut flush and drill out) and sanded the bottom of the key blocks enough to be able to add cardboard again. I have thought of retrofitting something like the Yamaha system of adjutable plates (a screw bearing down on what looks like nylon/teflon). Does anyone out there do that? Any comments on whether that makes more sense than removing wood from the bottom of the blocks, either from the point of view of long term adjustment or amount of time/trouble involved?
