[pianotech] stuck action

[Tom Driscoll]

Joseph,
 That is a creative approach to the expanded bracket issue, but you stated 
it's problem with the time it takes to both make the tool and to turn the 
little suckers down. The brackets are toast anyway so my vote is to break em 
up ' .   5 minutes of satisfying destruction  and the hammer rail will drop 
down.
JMO.
Best to you,
 Tom D.
