That said, the key has to be friction free = enough and weighted appropriatly. It simply has to get moving on its = own. Not much you can do except regulate checking as high as you can get = away with, get rid of excess friction, and make sure you have enough = weight back of the balance rail pin.=20 Cheers RicB Ed writes: I dunno what is involved in these actions.
