Step 3 Body assembly

Once I had decided to use the antiquated health machine for the torso, the rest was a matter of puzzle solving. The mechanism would cause the shoulders to rotate, so I thought that a spring in the waist might allow the whole torso to bob along in sympathy with that motion. A variety of springs were tested. A combination of a Volkswagen Jetta suspension spring and a portable road sign mount finally won out.
The head was then welded to the torso via a section of bent pipe. Positioning took a few attempts until balance was achieved.
Small cooking pots were used for shoulders and bolted directly to the bearings in the health machine. Then the railing arms and light fixture/vacuum handle hands were added. This again required some trial and error until things were relatively balanced and positioned so that they would not collide with other parts of the body.
