REFLECTOR: Hollow elevators

I'm still not flying, but I have some of the early Brazil-made elevators
(and canard, wings, ailerons).  I looked at Dmitry's photographs with great
interest, but they did not represent the construction of the elevators that
I have.  While my elevators are hollow, each skin is a glass/foam/glass
sandwich.  The pieces are bonded together with an adhesive epoxy similar to
the AeroEpoxy black & white epoxy that comes with the kit.

I needed to trim my elevators to length, so I have a little slice of
elevator (about a quarter of an inch long) that is very well bonded to the
aluminum tube.  I've been pushing it around on my workbench for at least a
couple of years, with no sign of de-bonding from the tube or at the trailing
edge.  I'm inclined to think I've loaded it in many ways that the actual
elevator will never experience, which gives me confidence that the actual
elevator will hang together just fine.

I think there must have been several different type of the hollow elevators.
