I use 3M panel bonder,......it’s a lot of overkill, but I never have a failure....JB weld ( slow set ) would work fine, .....of course, the trick is scuff the ends of the shaft, and scuff the bore of the tubing.....and prep clean with alcohol......the tubing is K&S engineering 7/32” ID tubing ....with either Lionel’s or MTH’s driveshafts, this is a very snug snug fit, so it aligns itself straight.....many ways to skin a cat, one could drill the pieces and pin them, but I like the clean look, and once the panel bonder sets, you’ll rip the brass in two before the shaft spins in the tubing.....
As far as the phase, yes that’s a topic for another discussion....being a mechanical engineer, I follow the millwrights guide....😉..
