I have a Jet JTM-830 vertical mill with a 7-inch wide table. Would there be anything wrong with using a 10-inch rotary table? It would hang over a bit, but it seems like it would allow for easier clamping, and machine table movement would allow me to cover the whole table. I obviously don"t want one so large or heavy that it affects the machine, but on the other hand, a 6-inch rotary table seems like it would have too many limitations.
I have a 12" Van Norman rotary table (probably 125lbs+) I use on all our machines, from the Grizzly Millrite copy to the VN 22L. I wouldn"t LEAVE it bolted to the table of the Grizzly, especially run way over to one side, but if the knee won"t hold that up, it probably shouldn"t be called mill. Get a big "un.
The 10" and 12" rotary table is fairly common in shops with standard Bridgeport mill types having a 9" table. The 10" should be adequate and a lot lighter than the 12"s. There are also 8" rotary tables. I doubt weight would be an issue for these smaller sizes.
Your assessment is right on the money. Buy the largest table you are comfortable in handling. I use a 12" and wouldn"t want one any smaller. It"s just too damned hard to make acceptable setups on small tables. If it weren"t for the difficulty of handling the 15" Bridgeport table, I"d have bought that in place of the 12" one I own.
I"d have to admit that the majority of RT setups using toe clamps do eat up the outer 1"+ of the table surface. Thereby reducing the working envelope if no other means of work holding are available.
That"s the one place size can work against you. I have the right angle plate for my Bridgeport, and it"s all I can do to put the rotary table on the mill when it"s mounted to the plate. A lifting device certainly wouldn"t be a bad idea, especially now that I"m older and don"t have the physical strength necessary to handle the table. I guess my advice might be tempered with the comment that it depends on how you"d use your table--------the smaller tables can be easier to use when doing horizontal work, and don"t eat up spindle clearance quite as much.
You could always buy a smaller table and then add an aluminum sub table to it to make it larger. My table is 8" and I plan to make a 12" table top 1" thick. Then you can drill and tap it for clamps or whatever you prefer.

That"s an excellent way to extend any rotary table. I have a plate that is about 16" diameter that pins to the center hole of my table for quick setup. I also drilled and counterbored the mounting holes so nothing is above the surface when it"s installed. As you suggest, it"s easy to drill and tap holes as necessary.
This is how that can work. This operation is milling radiused cheek horn slots (to 11"R) on locomotive axleboxes. The "plank" is a piece of 3/4" steel plate picked up as scrap and surface prepped. The DTI at right is placed so as to indicate rise of table and therefore exact depth of cut.
The rotary table is a restored 9" Troyke (ca 1949), a grimey lump picked up for peanuts on eBay but which turned out to be virtually unused under the grunge. I"m not sure of the weight of this but it"s about the heaviest table I"d want to lug around the workshop and keep off the machine and mount it each time I needed to use it.
I"m very interested in this discussion. I have a Jet JMD-18. My rotary table is an Enco 6" dividing head that rotates from horizontal to vertical. The vulnerability of smaller RT"s is rigidity during cut. On a few occasions, I have had minor rotation during the cut, and it"s difficult to re-set the point of origin after that.
I, too, am contemplating an 8" table. Still, 83 lbs dead lift ... My 100 year old L.W. Chuck 6" vise is about 60 lbs. I"m no weakling, but it"s a challenge.
