If you don't have PFA-style approvals to deal with, I'd consider
splicing the tubes together with a length of 1-1/8" x .058 tubing and
rivets and cutting again to length. This is an approved method here
(FAA's Aircraft Inspection and Repair, Chapter 2) for aluminum tubing,
including structural members, not just control pushrods here under much
less stress. You can add structural epoxy adhesive to the splice if you
like, as that alone w/o the rivets is the actual construction method in
the Grumman line of singles for the looong aileron torque tubes!
