S&S upright actions

[Jorgensen, Michael L]

Could the capstans be not far enough under the wippen heels, or the action bracket feet be mounted in too far, thus reducing wippen travel for a given keydip?

> Problem:  Steinway uprights, 1 "K", 1 "X", and 1 "I", the first new, the latter two rebuilt by yours truly.  All have hammers the bobble.  I have rebuilt other Steinway uprights and serviced others of similar vintages which had no problems.  From the best I can tell the jacks start too far under the butt to clear the butt without extremes amount of dip.  In the "X", out of desperation, (I was at a customer's home, far from my home and didn't want to make another trip) I removed all of the butts from the center of the piano (double flanges), removed the jack rest felt and shimmed them out about 1/16".
