Another view. The holes for the clevises should line up wiht the
pivot pin in the rudder.
A 3/16 carbon fiber tube was used to make a rudder push rod. 2-56
threaded wire was inserted in the end with a 90 degree bend that
extended through a hole drilled 1 inch from the end of the tube
to lock it in place. A channel was ground on the opposite side of
the tube which allowed the wire to be inserted. The
inserted wire and channel was filled with gel CA and wrapped with
carbon fiber tow secured with thin CA. The rudder bellcrank
connectors are made from brass rod ends soldered to small wire terminal
ends that have had the insulation removed. Kevlar thread will be
used for a pull pull rudder control.
