Build continues and upgrades plus review.

In standard form, vertex rotabs have the worm/handle on an eccentric so you can engage/disenage the worm and also adjust backlash...

Yes, the way I converted mine means it still does...however I've tried that and I think the worm gear might be too far gone for that to help.

Take it apart and check it. The worm wheel is just cast iron bolted onto the underside, which i discovered after removing several teeth while machining a bit 1/2" thick steel into a 12" round :-/
Someday, once I've got the mill converted, I'll get it converted into a 4th axis.
