Yep, the old indexers provided a way to to limited 4th axis work on a

axis capabilities so indexers are a thing of the past, but they're still
plenty handy.

I have a fourth axis CNC rotary table (I do not remember if you saw
it), but I have not wired it yet, it is going to be pretty time
consuming. I will use the indexer for now.
