Bracket

Made a ⅜" thick bracket to hold the Sherline CNC rotary table on the Taig table, vertically.
Added a second support bracket for additional rigidity. A ¼-20 cap-head bolt secures its base.

Stepper Motor Mount

Added a side bracket with two setscrews (with locking nylon inserts) to aid alignment & reinstalling.

Elongated slots are for 10-32 bolts.

Four steel T-nuts hold it down to the Taig bed.

Indicating

Indicate the rotary table face by performing adjustments both horizontally & vertically.

Tramming the 4^th, A-axis using the 4-jaw adjustment method.

Tramming Animation

A-axis tramming animation. Note the degrees scale. Iteratively adjusted opposing pairs; 0-180° & 270-90°.

Practice cutting a spline using the 4th A-axis. 3-jaw chucks are simply not accurate enough for this application.


Sherline CNC rotary table & 3-jaw chuck being using with their matching tailstock mounted on the OEM base.
Bracket slots were elongated (milled) to provide greater adjustment range for use on the Taig mill table.
The tailstock can also be adapted for use on the Taig lathe.
