centerline at the marked position. Be especially careful when
penetrating through the backside of the rudder.
Step 3.
Using an 8-32 tap, thread the hole that you just drilled
in the rudder.
Step 4.
Mix a small amount of 30-minute epoxy and lightly coat
the center of the threaded portion of the 4" long 8-32 bolt
included with the Rocket City Swivel Horn package. Thread the
bolt into the tapped hole in the rudder until 1" of thread is
exposed on the opposite side.
