After the tail surfaces dry it is time to glue in the elevator horn.

Begin by grinding off any extra epoxy at the joint. Then follow by drilling a hole for access to the horn.

Pin the elevator horn in place and center it so that it is between the sides of the rudder.

Make a dam out of balsa to keep the epoxy out of the hinge line.

Mix some epoxy (Skin-It) and micro-balloons until there is a thick mixture.

Dab the epoxy mix it in place and let dry.
