The individual units here are forged from 1/4 round stock. The starting pieces were about five feet long. As completed, each 'ball' consumed about two feet of material, so the completed mobile sweeps out about 3 feet from the central axis. The linking cables are about 4 inches long (so the whole piece is about 20 - 24 inches in depth)
Quad State happens over September 21 - 23, at Troy Ohio. It is a large regional blacksmith's conference, typically some 600 - 800 in attendance. It is well known for the care used to select demonstrators, plus a massive tool sales area.
My close friend David Robertson will be one of the featured demonstrators this year.
