First, you would adjust the dampers to lift evenly.

Measure the distance from the edge of the hammer rest rail to the damper
head.
Remove the stack and wedge-out the damper lift rail until your reproduce

that measurement.

Lift each wippen and adjust the spoon to lift the damper when the hammer
is 
at mid-blow.
For actions with wooden damper lifters, adjust the screw on the lever.
(The 
damper wires
would have to be judiciously timed to allow for the narrow margin of 
adjustment with the screw).

	Excellent suggestions for regulating dampers in these actions.
One problem I've had is that the wires in the damper levers are thicker
than most and are difficult to bend without breaking the levers. I have
used parallel pliers to grab the lever just below the wire to protect
against breakage. The problem IMHO ,is a combination of brittle old
parts and a resistance to malleability in the wires
