I didn't do any regulating, and didn't have much time to study the action.

I wish I had my digital camera with me...... The key has a stick protruding from the top at the capstan location that is connected to the key with an action center (pin, bushings, etc). The stick is just a half-inch or so long. A capstan with threaded rod protruding from both the bottom and top are screwed into the stick on the bottom and the wippen heel on the top. If you turn the capstan clockwise, it screws into both the wippen heel and the stick, thus bringing the heel closer to the key - turn it counterclockwise and the opposite happens. Looks like a really neat system where you would get no friction loss at the capstan/wippen heel interface. I wonder how much fun it is to remove the stack? Anyone see this configuration before?
