Elevator control tube connection...

Curious what others have done. The plans call for a piece of 3/4" sq tubing to be affixed to the end of a piece of 3/4" round tube. That presents a sort of round peg, square hole scenerio.

My question is, why can't it be something along the lines of what the plans for the Acrosport show. I really so no apparent reason it couldn't be. Am I missing something?

I thought the same until I made the part. When you cut the V into the square tube it gives a perfect line to weld on. I think it's an easier weld than the drawing you referenced.

I saw your pictures. I think I may just construct it like the control yokes. Mill a radius in the end, bend a u-Channel then straps welded along side. I just can’t see any engineering benefit/difference from either of the drawings. Guess just different ways of skinning the same cat.
