UPRIGHT DROP ACTION
SPINET
Gray shaded areas are felt parts.
This
"drop action" design is more precise and easier to service
than the wire
and elbow arrangement below.
This action is found on Baldwins and a few other
pianos.
HERE
IS THE MOST COMMON "DROP ACTION"
WITH THE WIRE AND ELBOW ARRANGEMENT.
The
table below is the same as the Upright Action elsewhere,
so don't be bothered
if you notice a few numbers
which do not appear on the above diagrams.
