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!

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. Larry H. Serge VIDAL <serge.vi...@sagem.com> wrote: What use were they sold for, exactly?

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. Sid Wood KR-2 N6242 Mechanicsville, MD, USA 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.
