The switchable magnets is the most satisfactory project I have built to date.
This full build video demonstrates all the important steps needed to build the switchable magnet, using popular and available tools: drill press, miter saw, table saw. For someone who only has drill press, there would be a bit more hand cutting and filing required, but still possible to complete the build.
What makes it so special is the fact I used the Nikola Tesla handwritten notes, which I followed despite they didn't seem to follow the common logic or sense. And towards my great surprise, the switchable magnet works and it exceeded my expectations.
8x 1 cubic centimeter NeoDymium magnets are the heart of this device, combined with 2x 1 square centimeter profile iron bars, around 7 cm long, serving as a frame and the magnetic field loops conductor and amplifier.
The Nikola Tesla design is different from the most popular switchable magnets on the market, and the magnets arrangement is totally different, which is why it didn't make a scientific sense at first glance. Now I do fully understand how it works, and I take my hat off to the genius of Sir Nikola Tesla. His handwritten notes were a bit cryptic as well, but I'm happy to have figured them out, and after numerous prototypes and thorough testing, I found the best proportions and configuration, to achieve the best magnetic field amplification.
A single switchable magnet can lift up to 6 kg = 13.2 lbs. And it can withhold the force at 90 degrees on the steel surface (table saw / bandsaw / drill press) up to 6.7 kg = 15 lbs. Of course combining more switchable magnets will multiply the holding force capabilities.
Because it is fully made out of metal: aluminum, stainless steel, mild steel bars, neodymium magnets, this switchable magnets are welding friendly, which expands their functionality even further than just woodworking machinery assistance, such as jigs / fixtures / magnetic fences / feather boards / miter gauges / stop blocks / cut delimiters and whatever your imagination brings to your ideas.
I truly enjoyed this project, as it brought limitless satisfaction to me.
I spent a lot of time and resources while prototyping this build and making the final product, so your purchase of the build plans is greatly appreciated.
Thank you so much for watching and your support!

At Tiger Carpenter, I use both hand tools as well as power tools to make furniture and woodworking jigs.
I put a lot of thought into the design and optimization of the furniture and jigs I make. I like to come up with the improvements of the tools or jigs that are already out there, and share my ideas or findings with the community so that we all can benefit from the new upgraded versions or iterations of each invention.
I also implement the principle of aiming for perfection, even though I make a lot or mistakes and errors like all humans do. I learn from the mistakes I made, and I raise the bar for every next project.

very clever fixturing! The two things that amaze me about master machinists are 1) holding awkward parts and 2) planning the order of operations. Sort of like a championship billiards player who has the table run in his head after the first shot! EXCELLENT
Nicely made, it is amazing how the iron bars magnify the magnetic power and to have it in a really handy package that you can turn on and off. Good work.
yes thanks to the handwritten notes by Nikola Tesla
these Switchable Magnets are selling like hot buns on TigerToolsPro.com website.
also many people are supporting my efforts by buying the Build Plans.
PS
I actually sent you the Build Plans to your phone, not sure if you received them (I will remove this part of the comment once you get the plans either to your email, which I don't have or to your phone). please send me an email to info[at]tigertoolspro.com and I'll send you the plans.
I’d love to see a video on your favorite drill bits for different jobs. For example why cobalt instead of say Silicon Carbide, Stainless Steel or Tungsten?
I'm not an expert. Simply every other materials drill buys were either burning or breaking on stainless or hard steels and cobalt just keeps going and stays sharp for a long time. I figured it out by trial and error
The larger the drilling bit the slower the spinning speed.
this is very interesting to be able to see the time and effort and skill to manufacture your switchable magnet product. i especially liked the mock-up using the "iron wood." another very interesting video, thank you.
I had to use "iron" wood mockup to mockup the iron.
thanks for your appreciation of my efforts. it took quite a lot of time to build a number of prototypes and get it right. the videos sometimes make things look easy.
definitely upon the completion of his project I felt very satisfied.
I'm also very happy quite a few people have bought the Build Plans, which helps me keep the lights on
cheers man!
That wood is indeed actually called ironwood.
@@LBCAndrew yup I used iron wood because it's very hard, dense and can withstand great forces.
Już obejrzałam 😊
For how OCD you are with your drill bits, i'm surprised you don't use the drill press (unpowered) to start your tap to ensure a perfectly straight threading.
I use the lathe for boring and threading and it produces perfectly concentric results
The video shows archive footage from the time I was prototyping the build and didn't want to change the drill bit (setup) or I was simply lazy
This video is just to give you an idea, it's not a detailed instruction manual.
In the batch production mode we use totally different tools and technology, and we wouldn't publish it
Cool project, but how does compare cost-and-time-wise to just buying three Magswitch magnets for US$40 each and cutting a straight board for them to fit in ?
Nicely made, but I have to raise couple issues - there's no such thing as an M3 drill bit. Do you mean 3mm? Or do you mean the correct tapping drill for M4x0.7 (3.3mm)? For M6, the drill should be 5mm, not 'M5'. The rule for drill sizes for tapping metric threads is, subtract the pitch of the thread from the nominal size, so M4, 0.7mm pitch, 4mm - 0.7mm = 3.3mm.
Sorry but people are calling him a master machineist. A proper machineist would not have cheap tools.
I'm not a master or professional machinist.
However I have bought metal lathe and milling machine lately and now building these magnets or anything else has become much easier.
At that time I used whatever tools were available to me.
It also shows that we can achieve our goals even IF we don't have or can't afford super dooper tools.
PS
It's also quite sad to receive such a sour comment from a person who was born in the same country. Just saying...
