Second/thirding the advice to ditch that and get a chuck made for woodturning, you're gonna give yourself nothing but trouble and UFO's (unexpected flying objects) with that.
They make these adapters that will allow you to use any chuck with the much more common 1" × 8 tpi threads on your Shopsmith, and if you get one of the insert-type Novas, you can can actually get a chuck insert to fit. Here is the chuck body that would go with that insert.
For a nova chuck, this is the insert you'd want for a shopsmith:

I'm sure you could probably make a jig similar to the one he uses if you got a smooth bore insert for the chuck like this one, insert a 5/8" rod, and clamp the other end into a bench vise. It wouldn't have the same articulation, but it would certainly be more stable with less of a chance of damaging the lid. Hope to see pics when you're done!
