Rotary table for milling machine

I have a 6" rotary table (BB) and a 7 7/8" dividing head (Shars). I use the dividing head more often than the rotary table.
 
I have a 3" rotary table -- bought it for the cx600. Never used it. way too small. Its for sale
 
In Ontario that table, in that condition would have sold for $400 to $500. It is WAY oversized for your mill. Why don’t you sell it and use the profit to get a table you’ll be able to use?

The only aspect of the rotary table that could be too much for your mill is the overall height. Is it usable? If so, heavier is better in my opinion. It adds mass to combat any tendency to vibrate or chatter. If it is too tall then it has to go. I figured that out after purchasing a 14" KBC Rotary table for my big mill and then realizing I didn't have enough height. Any one want to buy a brand new 14" rotary table?
 
I went through this issue when I had my RF-45 mill. Which actually had about the same Z headroom as a 9x49 Bridgeport without spacer. Its amazingly hard to find low profile RTs. This 6" platen is 3.3" tall, but I seem to recall the dials must overhang the table. At least it has a 90-deg face, some do not. The quality varies by vendor.

But anyways you have to factor what you potentially might be mounting to the plate from the bottom (chuck body + jaw extension + work piece) and what's coming down from the spindle (chuck, EM holder, cutting tool...). What's left in between in the middle is what you are left with. A tooling plate can sometimes be a better solution but its job/part specific.
