Wood and Brooks direct blow action

[Ron Boyd]

Thanks Dave. It doesn't appear that this piano got much use over the years
as there is very little wear on the hammers or the action. I pulled the
action today and was surprised that the dampers didn't come with it. I kinda
like that feature as it makes pulling and installing the action pretty
easy..............Ron Boyd

Ron, 
I worked on one just the other day. It's the first time I've encountered one
of these actions. The piano (Gulbranson) has loose tuning pins after being
moved to many parts of the world N.Y., Ecuador, Hawaii, California and now
in Las Vegas. It's on the books for a CA treatment after our monsoon season
passes. Amazingly the soundboard showed no signs of cracks, separations and
still maintains a small yet positive crown but the bass bridge has lineal
failure along the hitch pin side with hairline cracks at each pin. My
clients wishes are to keep the piano for a year or two until they can afford
to replace it. I found the action to work adequately. The parts were all
worn but the overall regulation worked well enough to a controlled sense of
touch. I didn't care for the catchers as it gave a lumbering feel to the
repetition. A sense of gap is the best way I can explain it. Some of the
jack springs had to be replaced and I had to pull the action to access the
spring holes. The screw type of damper lever contact seemed like a good
idea. If I had my camera that day...................
 
Not much information here just my observations.

Last week I posted an e-mail to the list asking if anyone had information on
the Wood and Brooks direct blow action. As of yet no one has answered me. I
would also like to hear comments good or bad about this action. This piano
(Gulbranson) was built in  the late 40s and is in very nice condition.
