Recently I have been making some frames by hand from cellulose acetate again. It is very satisfying work but is very time consuming to achieve great results. Many years ago I invested in some very specialized equipment for frame making. Most of it is made in France and Italy. I purchased it from two factories in Sydney which closed down. The machine below is a pantograph for milling the inside cut. The pantograph is no good for one off frames as the tooling up takes too long. The machine below that is a wire shooting machine to insert the wire and hinge into the plastic side. It heats the plastic then pneumatically drives the wire core into the softened plastic.
