I have a Haas 5C indexer, similar to eBay item 310175166880, except mine
is a stepper driven model. It has a chuck on its nose also.

What's the resolution off the indexer?. I guess suitable for your gear
requirement.

I saw resolutions under a minute of angle.

I used to know a guy that specialised in gear cutting and broaching,
unfortunately now dead from leukaemia shortly after retiring, and he
had a number of Fellows gear shapers. His only foray into CNC was a
large CNC Beaver mill and CNC dividing head which he used to do an
order for a set of prime number master gears IIRC for a gear cutting
machine. That one required a fair degree of accuracy on the part of
the CNC dividing head.

Interesting. I believe it is far more accurate than necessary here.
