Well, depends. Now that I have a CNC mill, I have
sold my rotary table. Not much need for a flat
rotary table, except maybe for really large parts that exceed
the machine's travel, or if you mount it on its side as an
A or B axis. There are better units for that purpose, like
a dividing head.
If you don't have a way to accurately position the machine
in two axes, then maybe there is still use for such a table.
I'm curious, do you like to write clever CNC programs? Or just do it
all with CAD?
I just wrote this little gem that will cut a taper on my lathe.
Specify small diameter, taper angle, and DOC. I made it generic for
any future needs (This wouldn't run on any other control without

I almost never use CAD/CAM, ie. drafting in a CAD package and then
converting with CAM. But, then, I so rarely do anything that isn't
pure 2D work. Almost everything is cutting holes in panels.
So, I have a bunch of programs that write efficient G-code to cut
rectangular and round holes in sheet, and stitch the output of
these programs together to make one program for the entire
part. I find this to be WAY faster than CAD/CAM. The program
has built-in figures for roughing feeds and generates the
roughing and finishing passes from just a few supplied values.
I have versions for cutting the whole shape and trepanning, but
almost always use the trepanning version when the cut goes all the way
Sure, just make sure you have a hydraulic lift cart for transporting it from
the mills table. I was using a 15" today at work to rework part of an assembly
At home I have a 12" rotary still sitting where I unloaded it many years ago.

have you considerred something i call a die cart? It looks kind of
like this pic except its just a cable and crank to raise.
I have two, one slides under the roll-in saw when not in use, and the
other sits under the end of the large mill.
Like you, floor space is a concern with anything I buy. I already got
two pounds of shit in a one pound area.
