Build a Magneto Magnetizer / Imperfect

Build a Magneto Magnetizer Many people collect and restore old engines and in the process discover that the old iron magnets in the magneto have lost most mzgnetizer all of their magnetism. It’s always a good idea to periodically check the compass to make sure the north seeking needle still points north my compass gets messed up a couple of times a year and has to be remagnetized so it points properly.

Mzgneto my friend is a electronic genuis so he did all the real work.

Building a heavy duty magnet charger

The Square Deal Subscription Program is designed as a paperless transaction with automatic renewals at a preferred low rate. The single most important point in machining parts for this charger is to provide close fitting joints at all points in the magnetic path.

This arc is exactly what is wanted across ignitor points with battery and coil ignition, but in a magneto charger, the arc could lead to switch failure, insulation breakdown or electric shock. Apply a keeper to the magnet poles, switch off the current and withdraw the magnet sideways from the recharger. The current should build up to a maximum about 40 amps in about 3 seconds. Magnetomotive force product of amps times turns of wire must be large enough to bring magneto magnets to saturation.

I can see why you might have thought it was spam. Get fast, free shipping with Amazon Prime. Hi, My friend and I just did this. Top Reviews Most recent Top Reviews. Before the wire is wound on them, the magnet cores must be insulated.

My suggestion is to find someone who has the equipment and pay them to do it for you. This will not recharge newer alnico, samarium, and similar alloy magnets since these need an enormous magnetic impulse beyond the capabilities of this machine.

Diodes absorb the energy when the switch is opened. Mount the core with terminal end facing the lathe tailstock and run the lathe in reverse to make winding easy to view. What Engine for Clutch Pulley? This is important, because there have been cases where an enclosed switch has had the contacts stick closed even though it indicated open. Share your thoughts with other customers. No current will be indicated on the meter if the jumper leads have been improperly connected to the battery.

Sure didn’t try and spam anyone. No idea if this of any use to anyone or even if it works but when I came across the link by chance I thought I should pass it along to those REAL DIY’ers out there that tinker with the real magical parts!

We did it because of the challange. The one pictured has had the joints welded and additional braces welded on to improve strength. Amazon Advertising Find, attract, and engage customers.
