Many people collect and restore old engines and in the process discover that the old iron magnets in the magneto have lost most or all of their magnetism. With out a healthy spark, the engine won't run.
Here, Dave will show you how to build a device to recharge these old magnets. It's certainly not a novel invention. What Dave has done is show you how to build a proven device with currently available materials, and at low cost.
You can recharge old magnetos magnets, and create new iron magnets for experimental purposes. This will not recharge newer alnico, samarium, and similar alloy magnets since these need an enormous magnetic impulse beyond the capabilities of this machine. And besides these newer magnets usually don't go "dead" like "plain ones".
Dave will show you how a magneto works, how to test one, how the magnetizer works and will show you in detail how to build one. He'll give you all the tricks on building the base, winding the coils, building the power supply, and of course, on using the machine.
You can build this machine quickly and inexpensively. Dave will show you how to avoid what hew problems you might encounter. Great for engine restorers, science experimenters, or even as a science fair project.
Another good how-to manual from Dave Gingery.
Please note that we purchase this book from the USA, and it descibes a mains powered magnetizer running from 115 Volts, it does however provide some formulas that may allow you to re-engineer the circuit to run on 240 Volt.
