[CAUT] Baldwin Accujust

[Greg Newell]

Gerry, 

                Thanks for your post. I’m quite aware of the Baldwin
Accujust system. Whether the boards started out at zero crown or not is
immaterial to my reply to Benjamin. Continually adding downbearing over the
life of the piano will force negative crown eventually, no?

Greg,
If memory serves, the Baldwin boards had zero or nearly zero crown. Perhaps
some of the old(er) Baldwin gang could clarify. 
The accujust  (A.K.A. accu"snap") pins allowed anyone on the factory line to
string and adjust the bearing. Another plus was you didn't have to unstring
the piano to work on the board.  The plate and block all came out in one
unit. You work on the board repairing whatever then everything went back in
place with effciencies of time. The plate bolts (machined) allowed better
easier plate location in regads to the board and bridges. 
Engineering-wise it was a pretty well thought system from the manufacturing
point of view.
