For really long work, I've seen people have an end support similar to
the tailstock of a lathe. That might help quite a bit here.

If you want to, you might take a half inch thick piece of steel, make
a clamp on bed that can be aligned to the table, then mount the rotary
table on that. This gives you the effect of a small lathe with the
rotary table serving as the headstock. Do bear in mind that the work
will be springy regardless, and the use of a center rest may be
desired.

Vary the measurements to fit common sense and your design.
