I've done this many,many times over the years. Saved my hide on many the old upright and other out of production pianos. Granted, it's a last resort technique. It's clearly NOT the solution to the Samick problem, though. Next time you encounter one of these "squeeky tight" centers look at the pin with a powerful magnifying glass. The ones I've examined look pitted ,with bushing fibers stuck to it. A lot of folks think that there is some latent acid that is still in the cloth from it manufacture that, in combination with heat(friction) causes the reaction that messes up the pin. This can be further exacerbated by not enough clearance between the birdseye and the arms of the flange. A little heavy playing and it will freeze up. They *will* actually squeek. Protek and some other solutions help, but the permanent cure is to ream and re-pin, paying attention to the amount of play at the birdseye.BTW- if there is tightness here, file the arms,not the birdseye.
