Hey, while we're on a thread of DIY projects, my neighbor recently threw out a worn-out document shredder for the trash truck (it had chewed up too many old credit cards, I guess). I grabbed it and removed the drive motor from it and then put the shredder remains back for the trash.
The drive motor is about the size of a hand ball and runs on 110 volts AC so I pulled it apart, removed the armature and bearings and turned it into a magnetizer/demagnetizer.
You may have seen my first one, made from a removed oil burner blower motor, but that one admittedly has a YUGE! coil and is vast overkill for a shop magnetizer that gets used mostly for screw-drivers (but Tim Allen on "Tool Time" would absolutely LOVE IT!)
THIS one is much smaller, and while it can't turn a regular spark plug socket into a magnetized spark plug socket, it is just perfect for zapping screw-drivers and other iron-based tools and doesn't heat up while in use like it's big brother.
So, I give you the original "Ultra-Magnetron 10,000" and it's new, soon-to-be-a-Christmas-gift little brother, the "Magnetron 1,500 Lite".
Do not be fooled by the "Lunch-Time Salad Container" look - This is a serious piece of shop equipment designed and built to last for generations of use, assuming we're still allowed to have small hand tools in a few more generations. Fully fused and thermally-protected (as the original motor was) for operator safety, "The Magnetron 1,500 Lite" is the perfect tool for instantly magnetizing and demagnetizing any of your shop screw-drivers or small pliers - in fact, ANY small ferrous tool in your shop, with a simple pulse of the power button!
(Note: This model might not have enough poop to magnetize sockets larger than 1/8" and it shouldn't screw up your mechanical Rolex Oyster, but we haven't yet finished environmental testing so, in the meantime, don't wear a mechanical watch within three feet of these devices when in use - Caveat Emptor).
Never again will you have to hold a screw on the end of a non-magnetized screw-driver with one hand while trying to turn the tool with the other as the tool itself will hold the screw fast all by itself. When you're done with your job you have the option of leaving the tool magnetized or returning it to a non-magnetized state with the push of the "Mag/DeMag" button. The perfect multi-purpose tool!

Remember, these Magnetron tools are NOT sold in stores.
(In fact, they're not sold anywhere.)
But one just might show up at the Carlisle Raffle (if I find another motor to cannibalize).
