Being self-taught, there's a whole lot I don't know. So if some of the questions I post cause laughter, at least you can enjoy that.
I'm considering a rotary table for my mill and am wondering if this will serve as an 'indexing' tool also.
Thanks in advance...

Indexing is usually done with a "plate" in
the back. It's used for quick location. Were
as a rotary table is used for odd locations.
A rotary table can also do "indexing". The
rotary table has a handle to crank. Indexing
is pulling a lever and rotating till a pin falls into place. Buy the rotary table.

Sure, you can index with a rotary table. It gets a little tedious because you need to figure out the angular value for each index position which, if you're doing a 48-tooth gear or something, can get extensive. But you can do it with a computer program pretty easily these days, so it's really not that big a deal.
There may even be tables in Machinery's Handbook with it all figured out, I'm not sure.

Unless you have a horizontal/vertical rotary table, you may not be able to set up the work on the axis you really want, but even that problem may be solvable with a big angle plate.

Very definitely there are tables in the Machinery's Handbook for indexing check in the section 'Milling machining indexing'. Probably more information than you want to know on indexing. I would suggest getting a copy of an older edition of the Machinery's Handbook because there is more info that is useful for a tinkerer than in the newer ones - IMHO!
