Jacks to knuckles

[Newton Hunt]

There are two solutions to adjusting jacks to knuckles with dowel letoff
buttons.

First is to depress the key so the screw is a high as possible and often the
screw can be accessed above the dowels.

Second, Schaff sells a drop screw type tool by Yamaha that is severly tapered
to allow access between letoff dowels.  It really works.
