I'm finished.
I took the other plate I made, drilled two clearance holes for cap screws to connect to T nuts in the T slot.
Drilled and tapped 1/2 20 threads for the other bolts to connect to the plate.
Had to drill out smaller washers so they would have room to fit in the rotary table.
It was the easy way out, I could have made custom ones.
The apparatus sits on a cantilever of sorts and very ridged.
In last picture you will see one of my homemade T Nuts.
