Yesterday, I thought of something even easier. Why not:
1 - Cut a plug (made of Aluminum or Nylon) that will slip in the end of
the tube, with a protrusion;
2 - Cut an aluminum L-shaped part to make the horn; one leg of that part
will be horn, and the other leg part will be rivetted to the tube and the
plug, thereby holding the plug in place; The L-shaped will have a hole
that will match the protrusion, thereby preventing any rotational motion.
In other words, the horn would be simple plates affixed against each end
of the torque tube, and these plates would be retained two ways: by having
a perpendicular leg rivetted to the tube, and by having a protrusion from
a plug inside the tube going through them.
I ain't no mechanical stress expert, but my feeling is that would be
sturdy enough. And it would definitely be the easiest, lightest and less
bulky solution I could make without welding.
Actually, thinking of it, the protrusion could be made man ways:
- Either simply letting the plug step outside the tube (big hole in the
horn, then)
- Or milling the plug to a smaller diameter (smaller hole in the horn)
- Or drilling a hole through the plug and fitting a large rivet in (would
probably need a couple washers to make the the protrusion thick enough)
- Or putting a screw and nut through the plug.
Hmm! Can't wait to sneak in my clandestine workshop in the cellar to
experiment with that!

I am not sure if someone has already said this, I think they may have but
if you take a piece of square tubing that will slip over the torque tube
for the plaps, then take a piece of angle rivet onto one side of the
square tubing and the other side of the angle will cover the end of the
square tubing and round tubing inside of it. You could rivet the angle to
the square tubing on the one side in each corner of the square tubing
where the round tubing will not hit the rivets then bolt through the
angle, square tubing and round tubing.
Hope this makes sense.

My KR-2 has 6061 aluminum flanges for the flap bellcranks. I found them
in the local True Value Hardware store.
I drilled a 3/16-inch hole through the flange and ¾-inch aluminum tube to
bolt them in place.

That is pretty much what I have in mind, except I would like to find (or
make) an aluminum flange to replace the clamp collars, then glue AND rivet
that flange to both the torque tube and the bellcranks. The tube stops
could be made the same way.
