I am refurbishing a YC grand action. Hammer shank flange center friction is all over the place, so I am repinning most centers. Some of the low-friction centers have the following characteristics: First swing test - 9+ swings, then each time I test the swings, the number of swings drops by one. So after the ninth (or there abouts) swing test, I'm only getting one swing. What is that all about? And ideas? Terry Farrell
