I'm regulating a Knabe upright. Im having a problem juggling acceptable aftertouch vs. an acceptable amount of jack escapement out from under the hammer butt. With blow distance set at 1.75", let-off at 1/8", key dip at 3/8" and checking at 5/8".... aftertouch is about .040". With the dimensions as such the key feels like it plays well. In previous regulations I would have been very happy with this. However, this time I'm regulating according to Bill Spurlock's Vertical regulation pamphlet. In it he talks about aiming to have jack escapement be 1/16-1/8" out from under the hammer butt when the key is fully depressed. With all of the above dimensions in this Knabe upright the jack doesn't rotate completely out from under the hammer butt. Spurlock suggests decreasing the hammer blow distance to allow the jack to escape further. When I do this my aftertouch becomes too great. If rather, I increase the key dip to allow for more jack escapement aftertouch becomes too great again. In order to have the jack escape properly I would have to decrease the hammer blow distance to under 1.5 (I know because I tried it). As I suspected my aftertouch shot up, it was then .100. If I then decrease key dip, the jack doesnt rotate far enough. Then I tried to make my checking earlier. Even at less then .5 checking the jack doesnt completely get out of the hammer butts way before it is caught. What do I do????
