- Two quick remarks:
Just joined the list- very pleasantly surprised to find so many
people interested in this old show.
I am not a professional model or prop maker.
These things having been said, I _have_ made the odd bit, here and
there, for local theatre or convention use. The most important thing
to remember is... Verisimilitude. Most props, even the "hero" props
designed for close up work, are _surprisingly_ shabby.
Jewelry without backing, watches without internals... They are
designed to look _great_- for a few moments- but that's about it.
It's all about the _look_, in other words.
My suggestion would be to print one of the better scanner images-
using a high end color printer and decent stock. Print it full size.
Take it to a hardware store and see if you can find some sort of
metal end cap or fitting that looks to be the approximate shape,
diameter and depth to serve as the housing- otherwise go to a local
artisan or jeweler and see if they might be able to manufacture
Once you have the housing, get an exacto knife, cut the printed
color image to fit into the housing. That would give you an exact
looking "circuit board" including the inside of the lens. I suspect
that there is an electronics part or fitting- or even a cut down bit
of hollow tubing- that could be fitted on top of the lens image to
give it the right look. I also suspect that something like an old
hard contact lens- which where manufacured with a slight bluish tint-
might serve as the actual lens cover.
Even if you had to have the housing manufactured, you would only
have to do that-admittedly expensive- step once. Before assembling
the scanner prop, you could make a clay impression or something to
use as a basis for, say vacu-forming the thing- so that you could
cheaply make more of these. (Alternately, you could pass the cost of
manufacture on to someone if you intended to sell these.)
There are endless options here- depending on how far you wanted to
take this. Cutting and shaping bits of styrene for the left and right
side internals-they look like IC Chip sockets- so that they have a
little 3d feel, for example.
I don't know what would happen if you tried to sell these at
conventions- licensing issues- but I'd sure love to have one!
