Overview

This is a heavy-duty manual rotary table, a precision indexing tool used in metalworking to rotate a workpiece to exact angular positions.

Story

Before the age of computer-controlled robotics, the world was built by hand on machines like this. This rotary table was the 'GPS' of the mid-century machine shop, allowing a machinist to carve out perfect circles, radial engine parts, or complex gears with mathematical certainty.

Maker / Origin

While a specific nameplate isn't visible, this design is consistent with legendary manufacturers like Troyke, Bridgeport, or Moore.

Condition & Value

The table shows typical surface oxidation and 'shop grime' consistent with age. The ground surface appears relatively clean of major gouges, though the internal gears should be checked for 'backlash' or play. A thorough cleaning and lubrication would significantly restore its utility and value. Condition is fair to good for its age.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues

Best Venue
