The stabilizer and elevator spars are being aligned and the rod end bearing and eye bolts
installed. These are commanly called Dr. Dean hinges on the KR net.  You may notice
that I have large washers on the rod end bearing end of the bolt. On Helicopters I flew in
the Army we used large conical washers on rod end bearings to maintain contact if the
bearing should fail. I have been unable to find these conical washers and the large flat
washers interfered with movement of the rod end bearing so I opted to go with small
washers. My elevator will not undergo the stress of a rod end bearing on a tail rotor pitch
change link so I think it will be OK.

The stabilizer and elevator frame work is complete. Notice the elevator
balance horn extends all the way to the leading edge of the stabilizer. This
has been changed so that the balance horn goes only half way to the
leading edge.

Inside the gap has also been
glassed

The stabilizer is foamed and glassed

In this picture of the elevator the balance
horn has been cut down to half the distance
to the leading edge. Notice the circle on the
balance horn, that is a 3/4" 4130 tube filled
with lead to balance the elevator. It took 3
tubes of lead in each side to balance the
elevator.

Elevator and stabilizer finished product.
Well almost finished. I still have final
touched to put on it but for now it is
wraped in plastic and hanging high in the
garage out of the way. I don't want to
install it just yet because it takes a lot of
room and I'm afraid it would just get
banged up from being worked around.
