Trunnion for Sherline rotary table

Rotary axis trunnion.  Attaches to a Sherline rotary table. mounted with face vertical.  A second rotary table can be mounted onto the trunnion shelf ( flat mounting plate required is not included with this package).  Included Shelf is a 9 x 4 x 1/2 inch, cast aluminum fixture plate with 10-32 tapped holes on 1/2 inch centers.  Rotary tables, vise, and mounting base below are not included.  Mounts directly to a Sherline mill table using the Sherline t-slots.


The Trunnion table securely attaches to the face of the Sherline rotary table.  It stabilizes the assembly so a right angle plate is  not required.  With a trunnion table, 3 sides of a rectangular shaped part can be machined with a single clamping and simple 90 degree indexing.  Rotary axis machining can also be accomplished.

A Sherline mill vise is shown so that the scale of the mounting plate can be visualized. The area where the vise is placed measures 4" x 7 1/2".

This version is driven with an IMService Belt drive unit based on a Globe servo motor. It uses a 3700 Sherline rotary table, NOT the 3700-CNC version.

The base plate measures 1/2 x 4 x 14", and can be mounted to a Sherline mill table using the T-slots and standard Sherline T-nuts.  It is the same plate that is included in our Modular fixture tooling set.
