The metal mechanism table’s strategy has evolved considerably over the past few months. Originally designed for direct sale, then as a kit, it’s now clear that plans have generated the most interest. Since it’s winter and the workshop is rather cold, I expect to begin this final development push in the spring. It will be accompanied by a video series.
In order to make the project accessible I will be making a few design changes. MIG welding will be desirable but probably not required. 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).
I have begun a list of people interested in buying plans. If you would like to be added please e-mail me: firstname.lastname@example.org
(Above) Prototype cross-section, version in plans will be simplified.
(Below) Prototype dimensions, expansion % can be increased.
