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 set screws (with locking nylon inserts) to aid tramming & reinstalling.


Elongated slots are for 10-32 bolts.

Tramming

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


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

Tramming Animation

A-axis tramming animation.


Practice cutting a spline using the 4th (A) axis.


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. Also see small manual rotary table.
