The location of the pivots is not critical.  The closer to the base, the more counterweight mass is required and the heavier the entire sculpture becomes.  Upper part is balanced first.  Balancing the middle part includes incorporating the weight of the upper part (rotation of upper part is irrelevant for balancing).  Balancing the lower part is done last and includes incorporating the weight of both middle and upper part.  Counterweight mass is slighty oversized so sculpture has a tendency to be upright most of the time.  Box sections are hollow.  Titanium was used to reduce weight.  Too much counterweight mass would stop the sculpture swaying in the breeze.

There are a number of considerations to take into account:

  • Grease nipples.
  • No sideways slop / sway / being loose / gap.
  • Sculpture needs to be balanced; bearings don’t work well if not perfectly balanced.

Vertical rod (pedestal) rotation using gravity

Kevin Caron – How to Make Anything Spin Using a Thrust Bearing

A thrust bearing is a type of axial bearing and consists of an upper and lower race, with a cage sandwiched in between, containing small needle or ball bearings.  The needle bearings are oriented ‘axially’, like spokes in a bicycle wheel.

Drop a thrust bearing into a one-side hollow pipe.  Find a rod that fits inside the thrust bearing.  Weld a round washer a few mm from the base of the rod.  Insert the rod and washer into the hollow pipe.  The round washer will butt up against the thrust washer.  The rod will spin very easily.

Place a plain ball bearing at the top in between the rod and pipe to take the slop / sway out by ensuring there is no gap.

Or even better, use a linear bearing at the top:

Or even better, flip the whole thing upside down and have the outer rod spin and the inner rod stationary (to stop rainwater ingress).


Non-orientation specific rotation

This is similar to the previous scenario, except that it is not held in place using gravity.  This design makes me think of a garden gate hinge.  This setup remains intact when held upside down.  Click image to enlarge.
