Section 12: Installing The Linkages
10. Drill a 1/16" hole through the balsa dowel at the four
marked positions as shown.
11. Select one of the dowels and at one end make a second
mark 1-3/4" from the end.
12. Drill a 1/16" hole at this mark. This end of the dowel will
be used as the pushrod for the split elevator and will
require two threaded rods to be installed in this end.
13. Locate the three threaded rods and two unthreaded rods.
Cut 1/4" off one of the threaded rods on the unthreaded
end. This rod will be used in the hole you drilled in
Step 12. It is cut so that it will match the length of the other
threaded rod when it is installed in the balsa pushrod.
14. Using needle nose pliers, bend a 90° angle 1/4" from the
unthreaded end of each of the threaded rods. Also bend a
90° angle in one end of each of the two unthreaded rods.
15. Locate the end of the pushrod that has two holes drilled in
it. Find the shorter threaded rod (from Step 13) and insert
the 90 degree bend into the hole closest to the end of the
rod (1-3/4" from the end). Insert a standard length
threaded rod into the hole drilled 2" from the end.
