Globe Motor + Lead Screw = Confusion

The lead screw isn't that much bigger than the globe shaft, so you're probably going to need some kind of coupling so it doesn't break through. I'd recommend removing the threads from the last inch or so and getting a decent coupling kit from small parts or MSC. They're fairly cheep and fairly reliable. Whatever you do, avoid set screws at all cost!

Also, be very careful to fully support the lead screw in at least two places as the globe can't take ANY side loads.

That's sort of what I figured. I was just hoping someone would say, "It's okay, that'll work!" or something. They still can

Space is at a premium, so I want to keep everything as small and simple as possible. I'll shop around for shaft couplings.
