Andrew said: "You want the back edge of the jack to line up with the back edge of the spline in the knuckle and to rapidly reset under the knuckle each cycle..." This is totally incorrect! The forward edge of the wood moulding of the "knuckle" should be in line with the CENTER of the jack! Also, a blow distance of 1 3/4" is advised. A 3/8" dip is good place to start, but after-touch will dictate where it should be. Just so's ya know. Regards, Joe Garrett, R.P.T.
