Thank you all for the information. Will prepare for the unexpected :). Oh another question-why would SnS use these Billings flanges?

For example, I like not having to completely remove the flange screw when removing the hammer assembly. I like that I can space the hammers by slightly loosening screw and, using a screwdriver blade, prying the flange in the desired direction. Ron is obviously correct that swing-count is not a suitable unit of measurement to assess the pinning friction. Since you're dealing with some limited amount of sluggishness, why not try a few applications of naptha, along with 'working' the flange, maybe some heat, and maybe some Protek? I'm not sure how difficult repinning would be, if you did have to do so, but flanges would probably not be as tolerant of larger size pins as wood flanges. Schaff lists them in their catalog (Maroon cover, Pg. 128, Part #512.) Don says they're not left over APSCO and that they're good, so take that for what it's worth. If repinning, main concern is to not have any side to side slop. I'm guessing that, if you around 4 swings (holding assembly upside down using un-cut centerpin in pin-vise), you should be pretty good.
