Here's
a series of articles that will take you into factories in Britain just after
WWI and show you how wireless components were fabricated with simple machine
tools. The components they fabricated are exactly what you would expect Dr
Frankenstein himself to use in building his laboratory. Actually they were
sold to manufacturers of early radios (what the British call wireless): brass
stud switches, variometers, huge variable condensers, honeycomb coils, rheostats,
bayonet tube sockets, and much more.
You watch as parts are molded from phenolic (Bakelite is a phenolic) with embedded brass parts. You see panels being engraved with pantographs, parts being stamped out with simple dies, coils being soaked with varnish and centrifuged, and you even see an early wireless station.
You get a four part article on making radio parts, an article on the jigs and fixtures that were used to speed assembly, an article on the fabrication of honeycomb coils, a couple of simple coil winding jigs, and a great article on the manufacture of moulded electrical and wireless parts.
One
article will show you how headphones were made, from punching out pieces,
creating the magnets, to rolling threads on the plastic cases. You watch as
distributor caps and magneto parts are being molded with simple equipment.
And much more. You get production details. Precautions, hints, tips, ideas
for faster ways of doing things. After all this was written for at those who
built and ran factories.
Good stuff. Rare info. Maybe you could start manufacturing replacement parts for the antique radio restoring crowd. Or experiment with phenolic pressure molding. Or pick up ideas on coil winding for your own electrical/magnetic experiments. Usual how-to. Get a copy. And start building a lab better than ol' Doc Frankenstein could have ever imagined. Interesting stuff. 5 1/2 x 8 1/2 booklet 64 pages
