Measure hammer blow.

Move the hammer rail forward until the hammers are halfway to the 
strings.  Wedge the hammer rail in place. Tie wedge/rail/action bracket 
together.

Actuate damper pedal rod until the dampers just start to move.   If you can 
get a wedge in there that will help.  Tie damper rod in place.

Remove action and  put  in a cradle/stand.

Lift a wippen up until the jack touches the hammerbutt.   Since the hammers 
are held at the point where the dampers should start lifting and the 
dampers are held where they are when they are contacting the strings, you 
can adjust the spoons to just move the dampers when the jack hits the butt.

Try a sample or three,  adjust wedges as necessary to get the lift you need.

This indirect method isn't as accurate as doing it in the piano, but  if 
you can't reach the spoons, you can't reach the spoons.
