Big Bushings

[Farrell]

Or what about trying to duplicate Yamaha's approach to tuning pin bushings? Even if it required sizing the plate holes to mate optimally with a dowel or plug. Roger Jolly explained the Yamaha method to me one time, and I'm sure he did it well, but I still don't quite understand exactly what they do that seems to result in the bushing being part of the pinblock and/or plate. What about cutting plugs of Delignit, getting a real tight fit in the plate hole, maybe even a drop of epoxy on the base of the plug to bond to the block, and drilling the whole shabang in the piano in an effort to get a system that is more like an open-faced pinblock that your standard squishy/deformation-type tuning pin bushing?

Or is this just one more inefficient overkill idea?
