Two Tier
a product spinning automata

The appealing Two Tier is the 1st design in the product spinning series of automata that I am creating.  A biped works-out by both pedaling and pulling levers.  As a result of his work-out two product display tables (5″ and 6-1/2″ diameter) and one flag pennant are caused to rotate.  The product display tables are intended to hold products for display.  The two tables rotate counter to each other at different speeds.  This automata would be used in a customer-facing situation, such as the counter of a retail store, to call attention and focus to certain products or items. 


This series of automata is powered by a 110-volt gear motor.  There is no hand crank.  This automata is created primarily from a variety of woods, including Baltic Birch plywood, Pistachio, African Mahogany, Basswood, and Poplar.  The drive train includes stainless steel shafting and many ball bearings and is designed for long life.  The finishes include Wipe-On Poly, acrylic paints, spray enamels, and hand-applied and buffed paste wax.  The #1 of this series was created April 12 – June 4, 2020.


Jim’s Comments:  This is the first product spinner design.  The biped has interesting body motions and his actions are eye-catching.  The two product display tables rotate at comfortable and appropriate speed.  The pennant which you see flying beautiful blue painters tape, would ideally be flying store logo.  I find the ‘see-through’ base interesting and may do more of these.

Two Tier product spinner Project Sheet

As I create automata I attempt to update the Project Sheet weekly with narrative and images.  These project sheets are available on my website.  The project sheets give viewers a sense of what I’m working on and how I work.


 Two Tier product spinner Construction Journal page.

After an automata has been initially assembled and is functioning it is then disassembled and painted.  This Construction Journal is important to me.  It helps me to re-assemble, and it helps me remember ‘how I did it’ for future builds.  The Construction Journal documents with photographs a teardown and then the painted reassembly.  These documents are sometimes 50+ pages long.  The link above will take you to the Construction Journal, which you may download if you wish.
