I'm contemplating getting a Phase II horizontal/vertical rotary table for my IH mill. Any thoughts about which would be a better fit to the mill: 8 inch vs 10 inch? The price difference is only about $50.

Studying the dimensions, the 10" would be roughly full table width. In vertical mode, the table axis is 6.750 high (10") vs 5.985" (8"). The 10" is 118 lbs vs 83 lbs for the 8". Complete specs are in attached PDF.

The 10" has 6 table clamping slots, vs 4 slots on the 8".

I'd appreciate any suggestions, gottcha warnings, experience reports etc.

Thanks!!

If the 8" is big enough for your uses then it is a no brainer. If you need the 10" then DITTO !
as far as fittment to the machine, I have the 8" and may never really use it & didn't have any need for the bigger unit, The 8" does fit quite well but only sits one way now with servo mounted to it.

Generaly the problem with larger size Rotary Tables is getting the Endmill to the Part on smaller pices that are held in the center of the Rotab. when mounted vertical.
The Table itself will get in the way of the quill or toolholder.
To do these Parts often a riser plate needs to be mounted to get the part to stick out further to provide clearance to the table.
Between the 8." and 10" size both will have this problem, maybe the 10." a slight bit more.
Other then that a larger Table has a wider range of use.

Depends on the Parts you plan on holding with it.

As a hobbyist, I underestimated the weight of these things so bought the 8" table. Thinking bigger was better did't work for me in this case. I finally purchased a smaller 6" table and CNC'd it's and it nice in regard to weight and ease of setup and takedown. If you really needed the added height for vertical use, then go bigger but don't underestimate the weight and setup each time you need it.

Best Regards.
