Great idea for a DIY'er. I also very much appreciate the honest comment at the end of how this design saves money, but takes time. Suggestion - large headed bolts, heads down, screwed into place instead of metal rods. Inexpensive and if short ones are bought - no cutting.

[@sdcofer52]

I really like your honesty and straightforward approach. It was an interesting build, thanks.

[@daviddeboer87]

I appreciate anyone that takes the time and trouble to produce a video, more so if I find the information useful. This was great, helpful hints, pointing out possible mistakes, detailed instructions, honest comments about purchase versus DIY. Perfect, thank you.

Thank you David, glad you got something from the video. Oddly enough I’m now employed by Magswitch and this is the video that started me down that path. Life is funny

[@gfotinakes316]

Nice job! You might want to mention that when you sand the surface smooth, make sure not to heat up the magnets as high temperatures cause a loss of magnetism.

Your sales pitch at the end was spot on... That was very cool to watch, thanks for sharing.

It was kinda an anti sales pitch, haha

[@davidhmorton]

Andrew, congratulations clever design. this "platter" design is similar to a design from GM, patented in 2005. By the way Ok for people to still build but, u need permission for commercial products. Magswitch has different platter design, we use different sizes. 10mm. 15mm, 20mm and 30mm. The sizes effect field depth and smaller is stronger, relatively, than the larger on thin material

Glue sticks, not hot glue, work well for glueing paper templates without a mess or squeeze out.

[@judy-9999]

I thought “glue sticks” are used to make “hot glue”??? BTW ~(since I’m here)~ Can someone tell me if there are glue sticks of different “quality’s” that work better than others, cause the dollar store glue does NOT work well, 🤔🗯 BUT MAYBE it’s because of my “glue gun”? ... also from the dollar store 😕 THANK YOU for helpful replies & suggestions 👍😊

[@PablumMcDump]

@@judy-9999 While the rods that go into a hot glue gun have come to be known as glue sticks, David was referring to the kind that children used in place of liquid or paste glue in school -- essentially a thick paste glue in a lipstick dispenser.

Super strong magnets! Why not make the outside shape rectangular so you have a reference surface that is flat and consistent?

[@abcaabca6364]

Actually 6-sided would be better for installing all the magnets (and drilling their holes).

[@KarlBunker]

This would have been a lot more interesting if you had done some explaining about how and why this thing works.

[@root1657]

Even the Insane Clown Posse doesn't understand magnets, how do you expect anyone else to figure it out?

[@Laugh1ngboy]

The steal posts are separate. When he turns the top they align with the ones on the bottom and transfer the magnetic field to the bottom posts. Turning them on.

[@root1657]

@@Laugh1ngboy Nothing is stolen. Also, the steel posts are aligned in both positions, however, the magnets are arranged so that in one position they line up so that the top and bottom work together to make a much stronger field, and in the other position, they are aligned so that the magnets of the 2 layers basically cancel each other. This is why the magnets have to be alternated. If they weren't alternated, then this wouldn't work, because there would be no difference in what is lined up in the different positions. If you really want to suck all the fun out of it, check out the explanation here: www.kjmagnetics.com/blog.asp?p=magswitch

Very similar to Larry Fullerton's "Correlated Magnets," a technology that you might be fascinated with.

[@ElectricGears]

I've often cleaned metal filings from magnets by padding/rubbing them with duct tape.

[@TrevorDennis100]

Andrew, I am really pleased to have found your channel (via James @ Stumpy Nubs). I'm a retired engineer/toolmaker who has discovered the joy of working with wood in my retirement, but I still love using the metal lathe and milling machine as much as the wood shop machines, and I am seeing some great project ideas already. I will absolutely be making a switchable magnet, but probably not copying your design exactly. BTW I have a pretty cool vice project getting close to being finished, but nowhere near as elaborate as your twin screw vice. That is a thing of beauty!

[@andrewtirado1778]

I’m an artist, and often work on very large canvases/panels. Up until now, rather than use an easel, I have used a cleat system where I have what looks a bit like a ladder mounted near the wall with “rungs” comprised of wood cleats with the top edge beveled back 45 degrees, and a corresponding piece of wood screwed to the back side of the panel with the other half of the cleat, bottom edge beveled back 45 degrees. Then, I can simply slip the panel onto a “rung” at the desired height rather than have to climb up on a stool to work on parts of the paintings. But it’s a pain, with larger panels, to have to ask someone to assist me in raising and lowering the piece onto different rungs. So I’m making a new system without cleats where a winch will do the raising and lowering of a sled that will somehow connect to the back side of the panel. Only, I’ve been stuck trying to figure out how to securely connect the panels to the sled. What I want is to be able to slip the panel onto the sled while the panel is resting on the floor. Compounding things is that I’d really like the option of rotating the paintings to work on them inverted at times (when working abstractly). All that to say that while your video has given me a good solution that should allow me to not only secure a panel to a sled but also rotate it. I think I’ll want something like what you’ve made, only more like 2’ in diameter, with more magnets, and the ability to do a full 360 rotation, not just a back and forth, on/off.

[@ryanroberts6226]

I used the large template and 50% sized the plans and used 1/4" rod and magnets. It worked pretty well and for cutting the rod, I drilled a hole through a chunk of 4x4 ane pushed theres through to length and used a metal blade on my sawzall.

[@dougcox835]

Just a suggestion to make it easier to build. In the beginning you glued the template to the wood. If you buy full sheet labels and print it out on that it'll stick right on without glue.

[@valveman12]

Nice project. The metal rods are placed to provide a stronger concentration of the magnetic flux within a smaller area.

[@Sebastopolmark]

GREAT build and HONEST review.

[@abcaabca6364]

I just downloaded the wooden mag switch plans. They do not include any dimensions, in particular: 1) the thickness of the plywood 2) the lengths of the steel rods 3) diametric location of the small rods 4) diametric location of the arcs Scaling from a print is poor practice. The video says to make the Base and Mount from 1/4 or 3/8 plywood. The large design uses 1/2inch dia magnets, so 3/8 plywood will not work for the Base which has radial holes. Noting that 12 magnets are used would be helpful. Your source for magnets has increased the cost to $21.50 for 12 large magnets. They are out of the N42 design. But for modestly more, the N45 are available. Any idea if the N42 and N45 ratings are accurate from this place? The quoted pull strengths are 1.5x to 2x too high. McMaster reports lower pull strengths for the better N52 magnets. McMaster is an authoritative source. And a Magswitch 150 now costs a bit more than twice the magnets from your source. Of course, the Magswitch is metallic and smaller.

[@RobertSzasz]

If the the top and bottom of a post are the same polarity (switched on), to get to the other pole flux will go through whatever the magnet is placed on to get to the next post. If the discs are rotated so the magnets on top and bottom are different, a magnetic circuit is formed between the center post and the outer one and there would be almost no field strength on the outside. On. Off. (N-S). (N-S) (N-S). (S-N)

This vid just showed up and I noticed that you must be the guy that built Adam's new bench. Beautiful design of both the Bench and the switch. Is there any way to unlock (i.e. provide a slide option) on your vice design in addition to the two speed version. (on the bench) I know that the solid wood design is certainly a selling point, but I wonder about stability over the years. I used 3 layers of 3/4" mdf w/ Maple & Cherry top for my bench, but certainly think you did an absolute fantastic job on Adam's bench and love the steel frame.

A pair are good for lifting awkward sheet metal, put a 3x3 or 4x4 steel plate on the bottom with it turned on, swing it around to pick up nuts, bolts, nails, etc, then turn it off over your bench or sorting tray to release them. Same for collecting iron shavings after filing or grinding. Makes a nice clamp for use on a drill press or to hold two pieces of metal in place to tack weld (basically any function clamps can do on wood, one of these can do on magnetic metal, just don't heat them up or you'll have to replace the magnets).
