Stair Stepping Bottle Spinner
a product spinning automata

The delightful Stair Stepping Bottle Spinner is the 3rd design in the ‘product spinning’ series of automata that I am creating.  A biped steps on levers, which in turn drive a chain that incrementally rotates a 4-1/2″ display platform.  The display platform is designed to hold a bottle or a can. The ‘product spinning’ series of automata are to be rented into customer-facing environments, such as a counter in a retail store, and are responsible for the display of products of special interest or focus.

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, Myrtlewood, Basswood, and Poplar.  The drive train includes stainless steel shafting and many ball bearings and is designed for long life.  The finishes include WipeOn Poly, acrylic paints, spray enamels, and hand-applied and buffed paste wax. The #1 of this series was created July 29 – September 15, 2020.

Jim’s Comments; This is the third design in the series.  I’m glad that I’ve taken the time to create this automata.  It’s perfect for displaying a bottle or a can.  It’s quiet, interesting to watch, and yet allows the bottle/can being turned to be the focus.

Stair Stepping Bottle 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.

Construction Journal

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.
