Metal Mechanism Expanding Table

May 6, 2018

The metal mechanism table began as a kit but has generated more interest via plans. It’s been on hold since last winter but I continue to get e-mail requests and plan to refocus on it this summer. If you would like to be added to the list of people interest in plans: please e-mail me: scott@mechanicallumber.com

In order to make the project accessible I will be making a few design changes. MIG welding will be used rather than TIG. The frame will be steel. Automotive components will be utilized to build the central hub as they are widely available, high quality and affordable. Stationary machinist tools (mill & lathe) will not be required. Many other small changes are planned but these are the most important.

Dimensions from the prototype (cross-section below): 48″ initial diameter, 60″ when expanded, 5-1/4″ thickness, 50% increase in surface area. ( 70% expansion optional).
