Wim says, I've found that the easiest way to line up the knuckle is to do it from the back of the action. Turn the action around so that you are standing in front of the hammers. Raise a couple of hammers to the right of the jack you want to adjust. Lower the balancier of the wippen under the knuckle, so you can see the knuckle core and jack alignment. Reach around the front of the action to put the tool on the regulating button, and adjust the jack until it lines up with the knuckle. Yeah, what he says!
