Hello friends, I am building a prop machine for a show called "Frankenstories". I want the machine to be very reminiscent of the original lab equipment in Frankenstein. I have already collected several machines for old dials and switches. Th one thing (so far) that baffles me is the large insulators used? I believe they are called Pantograph Insulators. the large white or colored beehive stacked pieces on many of the machines? The few I have located are very expensive. I read that the actual builder Kenneth Strickfaden used turned wooden insulators on many of them? Any ideas as to what I should use or who might have any? I am not a carpenter and I will check local electric supply. But large items like that have long been out of use. Any thoughts? Thanks in advance.
