What brand chucks did you use?

Just measured... Pay attention to where the the holes for the chuck key end up. Mine all point to the front, and I made an extended key wrench to make it easier to access them.

I hAve a similar setup to Ray. I used a 1" thick square of Mic-6 with 6" Bison chuck. I usually drop it in the vise, but it can be bolted directly to the table. I put broken 1/2" end mill with the back end facing up to locate the center of the chuck/wcs.

Mic-6 is cast aluminum tooling plate that is guaranteed to be flat within a few thousand depending on thickness. The advantage being bo need machine the surfaces flat on both sides.

Cool. Where did you buy it?

Never mind, I found it for sale on online metals here - https://www.onlinemetals.com/merchan...=309&top_cat=0
$154 for 12" x 12" plate.

Do you think I could squeeze (2) 6" 3-jaw chucks on a 12" wide plate? I would really like to have (3) chucks on an 18" plate but that would be a squeeze for my Tormach's X travel.
I think the 3-holes in the bottom of the chuck could be rotated to fit in 12" wide but I have to make sure the tightening cam/key faces out like Ray suggested.

Don't forget that when the chuck is fully opened the jaws will probably protrude from the chuck body.

What diameter stock are you gripping? Does exact centering in the chuck matter for your work?

I bought all of mine from cdcotools.com.
