23. Mix up some 30 minute epoxy and milled fiberglass and use a small
blade to fill the 2 slots with epoxy. Use plenty of epoxy and be sure to
completely fill the two slots. Use an epoxy brush to completely cover the
areas on the rudder horns and base plate that will glue into the rudder.
Slide the rudder horns back into their proper position and immediately
wipe the excess epoxy from the horns. Carefully check and re-check
alignment to insure proper positioning. Use some denatured alcohol and
a paper towel to remove any excess epoxy. Re-check the alignment one
more time and set the assembly aside to dry. Repeat for the other side of
the rudder.
24.
Locate a 2mm ball link from the hardware bag. Thread the 2-56 ball
link onto a scrap piece of 2-56 pushrod. Cut the pushrod using
diagonal cutters leaving a 1/2” beyond the ball link. Drill a 1/16”
pilot hole in the center of the bottom of the rudder and 2” back from
the hinge line. Apply some 30 minute epoxy to the 2-56 threaded rod
and screw this flush into the bottom of the rudder. Use a little excess
epoxy to form a fillet around the bottom of the ball link.
