Measure the depth of the threads on the pin once you get it out Make a shim that wraps all the way around the pin. Insert the shim into the hole with the grit facing outward so that it's = sticking out a bit, not quite flush with the plate Pound the pin into the hole until there is about one and one-half extra = turn's worth sticking up.  (Some people prefer to turn the pin in) &nbs= p; Put the string on the pin. Tighten pin a turn. Voila! The only time this didn't work for me was when I used to coarse a paper.=  It must have eaten away major chunks of pinblock. It should take about 5-10 minutes.
