Note Duet Movement Dimensions
I provide these dimensions
with a disclaimer: I highly recommend that you have a 100 note movement
in hand before building your box. It poses some interesting challenges
that you’ll need to deal with, which are too involved to deal
with without having the movement in hand.
The thin metal plate
the two movements are mounted on is 326.5mm (12 13/16”) X 91mm
The gears hanging
down below the metal plate are 34mm (1 3/8”) diameter, and
they protrude below the plate 29mm (1 3/16”). They are vertically
centered below the main gears at the left end of the cylinders, that
is 29mm (1 3/16”) in from the back edge of the plate. The distance
from the back of the plate to the face of the winding key is about
48mm (1 7/8”). This means the outside of the back of your box
would have to be about 1 ¾” from the back of the plate.
