Making a $2300 tool for $120! 

i was about to post something similar! Great work either way! A killer option for so many tools in the shop!

I thought the same things, but I really like his solution of the isolation plate. I'm guessing the isolation plate costs significantly less than an aluminum plate of similar rigidity to that steel plate.

Oh damn, nice idea. Some 6061-T6, three-quarter inch aluminum plate would be perfect, supply houses out by me so that stuff all day long.. I was going to suggest putting a copper plate between the steel and the magnet to block the magnetic field, but your solution is so much simpler.👍

Stainless is a great idea, I hadn't thought of that. Aluminum would be way cheaper and much easier to work with in my experience.

Thanks for watching Jared

its been a long road but after 7 years of working and reinvesting I have my own dream shop. You can too!!!!

Actually they rotate a cylindrical magnet that has north down one side and south down the other. When you turn the handle to engage the magnet the magnet is aligned with the north to one side of the block, and south to the other. The two halves of the block are magnetically isolated from each other by aluminum or brass or some other nonmagnetic material. This causes the entire magnetic flux of the magnet to flow from one side of the block through the table to the other side, which holds it securely to the table. When you turn the handle 90 degrees the magnetic north and south are at the top and bottom of the block, the magnetic flux is kind of short circuited because the sides of the block are both touching both north and south. The flux travels entirely within the block and it is easy to lift it off the table. When he screwed the steel plate on top and engaged the magnet about half of the magnetic flux went through the table, the other half went through his new mounting plate, greatly reducing the force holding it to the table. Incidentally, many permanent magnets, especially older ones before the rare earth magnets became common, need a magnetic keeper across the poles to prevent the magnet from losing its magnetism. This is why the horseshoe magnets that used to be used in science class had an iron bar across the ends when they were stored. This piece of iron or steel that shorts the magnet out is called a magnet keeper. In these lifting magnets, and in magnetic chucks on surface grinders etc. when you disengage the magnet the chuck body itself acts as a keeper. If you disassemble them and leave the magnets in a position where the poles are not bridged by a magnetic material they can lose their magnetism. That is why these types of devices should be stored in the off position whenever they are not stuck to something. This is also why many older magnetic devices like flashlights and magnetic tool holder bars have what looks like two steel rails down the sides of the magnet. The magnet is actually north or south on the exposed face, and the other pole is on the back. Those steel rails are actually the edges of a steel plate that touches the magnet on the back face, but not on the sides, creating a magnetic circuit when you place it on a ferrous metal object. If these devices are left unattached to anything (like a flashlight in your glove box) they may also lose their magnetism. The modern rare earth magnets like the neodymium ones that are used in most devices now have much higher magnetic persistence, and generally do not suffer from noticeable loss of magnetism, however if you do create a complete N to S magnetic circuit with one of them they will greatly increase their holding strength. The older magnets can be remagnetized if they lose their magnetism using an electromagnet type device that exposes them to very strong magnetic fields, and in fact the same device can be used to reverse the North-South poles in the magnet.

The acrylic easily made the magnet 2x stronger becusse of the isolation between the metal. The leverage added by the height was fine

@@MakeEverything Thanks mate. Subscribed!

I looked around my shop for a nice piece of aluminum to use but didn't have one on hand, I think the acrylic will do nicely though.

This is not a magnetic drill.

Nope, I'm first!

Neither one of you have a life, do you?🤣🤣🤣
