This type of coupler might be worth a look:

It is normally used to connect a hot water baseboard circ. pump to its motor and is only about an inch overall wide when installed.

The one I have here is for 0.5" shafts but could be bored out to 5/8" but might not be strong enough. Just a thought.

Imagining that thing spinning exposed is scary.

If you need hose for a drive coupler go to a farm store and get double braid hydraulic hose. You can also find it at a regular hydraulic equipment service center. Wrecker supply vendors also usually have it.

Rob, you won't have to imagine, see below.
I bored out the well worn example I have for a trial run:

Here it attaches a bandsaw. The coupling is 1.25" from headstock side to bandsaw side.

Here it is driving the bandsaw. A guard would not be difficult to cobble up.

You need the shafts lined up well or the coupling will wear through prematurely. My example came off my furnace just before failure and is severely worn so I did not try cutting wood with this lashup.

These couplers are designed to run for thousands of hours on a furnace but shaft alignment is usually near perfect. So, it appears like it would work, but all in all, I think I would not recommend this idea and would instead pursue a coupler involving a short piece of hose.
