Dangerous Electricity!

From out of the pages of Mechanics & Electricity Magazine and Modern Electrics Magazine prior to 1914 comes a collection of articles on high voltage and high power machines.

Here you get a major series of articles by Stanley Curtis revealing details of a Tesla coil you could build having a secondary 18" high and 5" in diameter. You get details on the coil, the condensors, power transformers, various spark gaps, and all kinds of unusual technology. Much of this, no doubt, ended up in Curtis's hard-to-find Tesla coil book that we once reprinted. Great illustrations.

Other articles cover the construction of a Tesla coil with a secondary wound on a glass jar about 4" diameter about 9" long, how to build a high-frequency resonator, how to build an X-ray set (don't aim it at me!), and a series on building an induction coil that could give a 6" long spark. And that includes details on insulating the wire, building the spark gap, constructing a motor-driven mercury interrupter, and even building, if needed, a plunge battery with mercury, potassium bichromate, and sulphuric acid. (If the neighbors find out you're doing this stuff, they'll drop a load in their pants! Dangerous stuff!)

And you get a number of short articles on high frequency electricity, building a miniature Tesla coil, a small carbon-arc furnace, a coil winding jig for secondaries, and a water rheostat.

These are the classic original articles. If you're an avid collector of Tesla material, you may have seen some of this before. But these magazines are very difficult to locate, and these articles that show you how to make everything from scratch are rare.
