I made aluminum wrist pin buttons or my '51FL. They are a finger press fit in the wrist pin hole, however I am second guessing, (over thinking), hand wringing if this is the right way to go. I do have a lump on Teflon, but . . . I don't know. Opinions from the more experienced are welcomed. Sorry to break up the oil debate above.
