Assemble the beater.
Parts: left and right beater sides, beater race, beater top
Hardware Bag C: 2X #8 x 1-1/2" Phillips truss head sheet metal
screws, 2X 1/4-20 barrel nuts, 2X 1/4-20 x 2" Phillips truss head
machine screws, 2X 1/4-20 x 2-1/2" carriage bolts, 2X 1/4" USS
washers, 2X 1/4-20 washer wing nuts
Attach the beater sides to the beater bottom: Orient the left and
right beater sides with their fronts facing forward, as shown
in Figure 9A. Set the beater bottom between the sides with its
grooved wide side (the shuttle race) at the front. Insert a 1/4-20
barrel nut into the hole at one end of the beater bottom. Insert
a 1/4" x 2" Phillips truss head machine screw through the back
hole of a beater side and tighten it firmly into the barrel nut.
Repeat for the other end of the beater bottom. Then screw the
#8 x 1-1/2" Phillips truss head sheet metal screws into the front
holes at each end of the beater bottom.
Attach the beater top to the sides (Figure 9B): If you wish, you
can put the reed in the beater at this point. Place the beater top
with its longer edge in front of the beater sides, so that the holes
in the top line up with the slots in the sides. From the back of the
beater top, insert a 1/4" x 2-1/2" carriage bolt through each hole.
Secure each carriage bolt from the front of the beater with a 1/4"
USS washer and a 1/4-20 washer wing nut.

Install the beater assembly.
Hardware Bag C: 2X 5/16-18 slim lock nuts
Orient the beater with its front side facing forward. Place the
metal beater supports onto the bolts pre-installed on the inside
legs (Figure 10A). Secure the beater with a 5/16-18 slim lock nut
on each bolt (Figure 10B). Tighten the lock nuts all the way, then
loosen one-half to one full turn to allow the beater to move freely.
