I have an 8 inch (202 mm) rotary table. The cabinet where it, my 6 inch (150 mm) vise, 10 inch (254 mm) sine plate, and my tilting table is set-up such that the shelf upon which each of these sit are the same height as my mill table. That way I only have to carry the load as I turn-about from one to the other. Each of these sit in a custom opening into which a set of (ø1" or ø25 mm) acetal rollers are inset to make it easier to place and retrieve these heavy items.
The area below the customized shelf has drawers for cutters and shelves for other goodies. There is a table area above the customized shelf with a rack above that for collets, mounted cutters, arbors, and the like. The whole thing has a footprint of (approximately) 48" X 20" (1220 mm X 508 mm) which leaves me an effective table of 48" X 14" (1220 mm X 380 mm). Pegs are mounted on the side of the unit to store things such as an indicol & indicator, vise drives, set-up screws, and the like.
After long days, I consider building a swing-arm to make passing heavy items from the mill (or lathe) to the cabinet easier. I have not yet gotten fired up to actually do it...
