Interesting thread....I've maintained for some time that the regulation of the jack-to-knuckle contact at rest is much more touch- important than I ever realized, and the more precision with which you can perceive what Ed Foote describes exactly----"We were taught at North Bennett to set the balancier so that we could feel the jack scraping, ever so slightly, across the leather of the knuckle when the hammer was at rest...."---the better that action's gonna feel. Allow your fingers, your body, to be super-sensitive. The goal is to just feel the scraping, and to witness a very slight movement of the hammer. Get more sensitive to your body, and your growth as a craftsman will accelerate rapidly. The more attuned you are to the feelings in your hands, your ears, your chest while you work, the more present you become, and the better technician you become; the more money and respect you get.
