In the case of this Young Chang, the bushings and pins are clean, showing no signs of verdigris. Usually, on a YC of this age, the real problem is in the PLATED centerpins. The plating seems to 'gaul' and make the flange(s) hang up. It's real unpredictabel and a real pain. Best "solution" is to repin, IMO. Joseph Garrett, R.P.T. Captain, Tool Police Squares R I
