    David,
    Kent Webb @Tech services - Steinway had me weaken the spring by bending.
    I placed it on a scrap of plywood covered the spring with a piece of 
leather and wacked it with a 2 lb sledge . Took two or three  tries to get 
it right
    This was a 1980's B and the pianist had to practically stand up to move 
that keyframe.
