Rotary table CNC conversion

I am using this 4" rotary table to convert into a 4th axis for my SX2 CNC Mill.

To modify the Rotary table you must turn the shaft down to .250 (-.002 +.000) to fit the coupling. You must replace the socket head screws with some that are 50% longer. I 3d printed one to test fit and function. I will update once I have a metal version cut.
