6) When you are sure that everything is
aligned correctly, mix up a generous amount of
30 Minute Epoxy. Apply a thin layer to the mount-
ing slot in the top of the fuselage and to the sides
and bottom of the vertical stabilizer mounting
area. Apply epoxy to the bottom and top edges
of the filler block and to the lower hinge also.
Set the stabilizer in place and realign. Double
check all of your measurements once more be-
fore the epoxy cures. Hold the stabilizer in place
with T-pins or masking tape and remove any
excess epoxy using a paper towel and rubbing
alcohol. Allow the epoxy to fully cure before
proceeding.
