The arm on the left points to a place on the model. The arm on the right points to the enlarged point on the full size enlargement. The model and the enlargement are on two turn tables which turn in unison with the chain, seen at the bottom. The arm pivots on a point and the pointer arms can move back and forth in unison. These movements allow the sculptor to take a measure from any place on the sculpture.
Next clay is put on the armature and the machine is used to find the correct proportions.
The surface is then scraped using the machine, and the basic forms begin to emerge. No details are seen yet but the enlarging process is complete. This is the point I am at now. The machine is just a guide and the real business of sculpting must now begin to take place. Next I will take the enlarged sculpture from the machine and put it on my workstand.
