There is no visible starter mechanism or anything apparently missing, apart from belts and my recollection was that the handle was simply turned and after a short time the voltage would appear. A good review of everything from friction machines to the influence machines of the early 20th century. When it does it produces a short circuit. The 5mm brass goes through this and is retained by a 3mm grub screw so the position of the charge collectors can be adjusted.

See the charge collector construction step for details. Posted by Jack Ritter August 1, January Learn how and when to remove this template message. Electrostatic machines have always seemed a little like magic to me. An extensive book about early radio systems nothing about electrostatics.
In practice, even a small residual charge on any sector is enough to start the process going once the discs start to rotate. pplans
With mm spheres, I measure mm KV sparks every 1 second. Shows the best schematics of the Voss and Wimshurst machines. I just checked before posting anything descriptive and I think my Dad made it.
French translation from the English original The two contra-rotating insulating discs usually made of glass have a number of metal sectors stuck onto them. Each would touch one of the two charge collectors of the Wimshurst machine and then they would slowly and without any other part of their bodies touching, bring their lips together for the inevitable "tingle" of wimsyurst.
A short piece of nylon forms a handle and a short piece of threaded rod screws into a tapped hole. Nice book about early oscillatory circuits and radio.
Wimshurst machine - Wikipedia
The rest of the circuit consists of a spark gap and two Leyden jars. The base is made from a mm pine shelf, that I stained to a dark mahogany. Scared the holy piss out of me!
I found a site kachine sold brass replacement meccano parts. Knick-Knack Shelf Kit — approximately 24" by 6". One can imagine wimshrst the visceral aspect of the Wimshurst machine with its spinning glass disks, crackle of electrical discharge, and the loud report of the six-inch sparks generated must have made it particularly popular.
Describes how to make early X ray machines, and includes detailed construction details of a Wimshurst machine  J.
Includes also reprints of old papers and many experiments with static electricity. Two leyden jars details of their construction details at http: An imbalance of charges is induced, amplified, and collected by two pairs of metal combs with points placed near the surfaces of each disk. Posted by Jake von Slatt January 30, Use a proxy in the USA.
Contains a rare discussion about doublers II, p. Tesla Coils and High Voltage. The discs are black, like pre-vinyl LPs but smooth and unsegmented — how does that affect the description of how it works? The most complicated operations will include some soldering but you will soon discover that attaching brass balls and rods in this manner is much easier then soldering integrated circuits or working with surface mount devices.
I cranked away for probably a full minute and nothing seemed to be happening at first, but after about 30 seconds I could hear the relatively loose foil wrap start to make a crackling noise, as if it were moving. Good reference about friction machines and many other electrostatic devices, with construction details discussed. This page was last edited on 27 Novemberat Excellent book on the history of the friction machine.
Flashing light prize Extreme Electronics. I used copper so I could easily make the bend around the motor.
Describes in detail the Leyser machine, Weinhold's version of it, and many other devices.
