This takes only a few seconds. Detail of the insulating end washers for the coils. The shapes and uses of magnetizwr pole pieces have been particularly well described in GEM May-June ’77, pg.

Build a Magneto Magnetizer SOLD OUT!

I used C steel for all components in the magnetic path. It would be very helpful if there were some pictures of the construction and use of this magnet charger. Try to keep the layers uniform with adjacent turns touching tightly.

The wheels were replaced with old lawn mower wheels which are stronger. Starting at a distance of about 12 inches, slowly lower the magneto magnet. The current should build up magndtizer a maximum about 40 amps in about 3 seconds. And beside these newer magnets usually don’t go “dead” like “plain” ones. Magneeto hardening, the fiberglass and resin were sanded smooth and painted. Unless this is done, they will lose their magnetism rapidly. Plus our Flywheel Forum column helps answer your engine inquiries!

Wind the coils on a lathe using back gears and clutching. Therefore, do not connect or disconnect the lead wires from the battery when the recharger is turned on. It is important that unlike poles of the magneto magnets and of the electro magnets be brought together; i.

Arc suppressor diodes The purpose of arc suppressor diodes is to reduce the high voltage arc produced by the coils when the switch is opened. All contacting surfaces should be absolutely flat and square so that there will be good metalic contact over the entire surfaces.

An ordinary automotive ammeter reading 50 amperes is sufficient. Ammeter The use of an ammeter, although optional, is useful to monitor the current through the charger. Gas Engine Magazine brings you: This charger uses 3-inch diameter soft iron core pieces 6 inches long, each wound with approximately turns of 10 gauge copper magnet wire.

How to Build and Use a Magneto Magnet Charger

What Engine for Clutch Pulley? Hi, My friend and I just did this. The easiest way to see if the poles are as marked is to test with an ordinary compass. What Engine for Clutch Pulley? Magbeto ammeter shown, unlike automotive magnetiser, requires the use of an external shunt for operation.

One washer for each coil should be prepared with brass terminal screws as shown. The main base is attached to the hand truck using the two pieces of steel angle cut from bed rails.

The north pole of the magneto charger can be verified by bringing the compass to about a foot from the charger pole while the current is switched on.

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 or all of their magnetism. If a lathe is not available, coils can be wound by attaching a crank with bolts threaded into each end of magbeto core. Diagram of connections of magnet recharger.

An identical washer without terminals is epoxied to the other end of each pole piece. Then lay it on its side with its poles away from you and extending just beyond the far edges of the electromagnet poles. The design The main criteria for any charger design is core area, number of wire turns, and buil of current flowing through the coils. The windings will heat up quickly when in use; therefore, the switch should be closed for only a few minutes at a time.

Knife switch Magnetixer choice of a knife switch has one big advantage. Gas Engine Magazine is your best source for tractor and stationary gas engine information. It’s important to state that increasing charger size beyond the point where magnet saturation occurs does not improve magneto performance there’s no harm either. Magnet wire is available from motor rewinding shops, transformer shops and suppliers specializing in magnet wire.

Before the wire is wound on them, the magnet cores must be insulated. When a magneto is taken apart for any reason, it must be assembled with the magnets in the same relative position as formerly, otherwise their polarity may be reversed and the magneto will be inoperative.

Probably a VERY good read Inspiring New Engine Bild. The figures show optimal vuild piece placement for charging most popular magnetos. Eventually some scrambling will occur, but try to keep it to a minimum. My suggestion is to find someone who has the equipment and pay them to do it for you. The exact number of turns is not important so don’t bother counting turns, just wind until 20 pounds of wire is on each coil. Repeat the procedure for the second coil except mark the terminals ‘3’ and ‘4’ instead of ‘1’ and ‘2’.

This material is too high priced so I used low carbon steel.
