Wong,

I doubt that a rotary table would be free enough. Maybe you could just mount it on a bolt with a couple of jam nuts to take up the end play. Then mount the bolt in the tool post of your lathe and the tap in the spindle. Use a bolt with an unthreaded shank so it doesn't chew up the bore of the gear.
