personal discovery

Hi Roger,

What was annoying was I had the back action out weeks earlier and had gone
through it, then installed it rough regulated and then later discovered the
wobbly lever...I may have over-stressed it somehow...Question:  When you go
through the back action what do you do?  This one had all the flanges glued
in and tight...would you have loosened them all and reglued?  Do you
install screws to insure against loosening later?  I'm still a little fuzzy
on aligning the back action to the keys...could you expand on that?

Hi David,
               I'm having a chuckle, I discovered the same thing in a
similar manner, only I was waiting for some damper felt on back order.
Been doing that way for a number of years.
On a rebuild I always pull, and service, the back action.  Even with
screwed flanges it is a hassle getting at them, when every thing is
assembled..
Another time saver: align the back action to the keys with the stack off,
and no strings on the piano.
Perfect unacorda every time.
Regards Roger

List,

So I'm here in the shop finishing up a Steinway M.  I noticed a wobbly
damper lever (dampers already rough regulated).  I put it off until finally
I decided I couldn't leave it.  I pulled the dampers and the underlever
system to  fix the problem.  Pinning was loose so I popped off the
lever/flange and repinned and then reglued and clamped.  I looked at back
at the piano and thought..."Hey this would be a good time to finish up the
let-off!"  So I installed the action and found I was able to align the
hammers, do let-off/drop, level strings and whatever I can think of.   WOW!
 This is the way to do it if your rebuilding a grand.  Restring, hang your
hammers rebuild action, whatever and then regulate the action with the
dampers out of the way.  Install your dampers at the end of the job...this
is probably common knowledge to everyone except me (and I've thought of it
but never actually did it)but if anyone hasn't tried this give it a shot!
