Step 15:
Preparing to install the Trapwork
Before attempting to install the trapwork, it is necessary to determine whether
there is enough room for the trapwork levers to operate without interference
from the rail cover or the pedal lyre.
To determine this you must do the following:
A. Install the pedal lyre
.
•
Mount the pedal lyre on the piano with the mounting screws, determining thereby
how much room there will be for the sostenuto lever, and other trapwork.
•
Re-install the
una corda
lever.
B.
Measure the distance from the back edge of the
una corda
lever to the edge
of the solenoid slot (See Figure 13).
•
If this distance is 3/4" (19 mm) or more, there is adequate room to install the
trapwork without additional modification. In that case, skip the next step and
proceed to Step 17, "Prepare the pedal solenoid for mounting.”
•
However, if the distance from the back edge of the
una corda
lever to the edge of
the solenoid slot is less than 3/4" (19 mm), there is insufficient room for the
trapwork to be installed. This will require making certain changes to the position
of the pedal lyre, and possibly the una corda (soft) pedal as well.
•
Please continue on to Step 16, "Modifications for proper trapwork fit".
