6. Lightly sand the end of the block using medium grit
sandpaper. Sand the end grain as shown in the drawing.
Sand this end
7. Use 30-minute epoxy to glue the 10mm x 17mm x
20mm hardwood blocks to the servo cover. Allow the epoxy
to fully cure before proceeding.
8. Position the aileron servo between the mounting
blocks. Space the servo so it is not resting directly on the
servo cover as this will cause vibrations from the airframe to
be transferred to the servo. Use a pencil to mark the location
for the screws that will secure the servo to the mounting
blocks.
9. Use a drill and 1/16-inch (1.5mm) drill bit to drill the
holes for the four mounting screws.
10. Use a #1 Phillips screwdriver to run a servo
mounting screw in each of the four holes. Make sure to
remove the screw before proceeding to the next step.
11. Apply 2–3 drops of thin CA in each hole drilled.
This will harden the surrounding wood, making the screws
more secure when installed.
Important
: Do not use a CA accelerator. Using
an accelerator will not allow the CA to soak into
the fibers of the wood, hardening the blocks.
