![Electromagnetic Drill press VISE [PLANS]](/img/1.gif)
This press has worked like a charm for my projects ruclips.net/user/postUgkxajoEbapTfqWaadnqb04h6U576yxXp-FE . I didn't even secure it to my table top, mainly due to the fact that I was using a 15 lbs drill vise. It's not flimsy at all as to what others have claimed it to be. Make sure the locking nuts and levers are secured and there won't be any issues with light pressure and patience. I was able to drill through aluminum, plastic, and steel (steel took a while) with no problems at all. Yeah it took a little longer than a regular drill press, but I don't have the space OR the money for one.The instruction manual was worthless, but luckily assembling the press was intuitive. However, the manual would be good for ordering replacement parts if needed. There is a nice breakdown of the parts that are included in the kit. Before ordering, make sure it is compatible with your unit, it is clearly stated what models the press is compatible with.This was an excellent purchase for $40!!
I've seen other magnetic vises on RUclips and this is, by far, the best one. Great explanation and video quality as well.
GENTLEMAN.... I HOPE YOU WILL EXPLAIN CLEARLY THE (CONNECTING) INSTALLATION THE ELECTRICAL WIRES TO GET THE SUCCESSFUL RESULTS .... from A to z.... please MAKE IT CLEARLY STEP BY STEP..... SLOWLY.... THANK YOU IN ADVANCE FOR YOUR COOPERATION.... WAITING FOR YOUR REPLY AS SOON AS POSSIBLE.....
SLOWLY....
*Fantastic job I would've guessed you were german from the engineering overkill lol. I was suprised the 60 grit grip tape was effective, was it an iron oxide grit? I took a slightly larger electromagnet and drilled a 1" hole in the center and wrapped electrical tape around the exposed windings. Mine's a complete hack job but took about twenty minutes and it's ugly but it works great! The hidden bonus you didn't mention is that flutes on drill bits and taps are automatically cleared of ferrous shavings instantly*
Seen a couple of videos making one, this is for sure the cleanest build so far, just how i like to build stuff. thanks for sharing
I have to say your video is one of the best that has shown how to build this. I don't think the other channels really go into the wiring detail like you did. I'm fortunate enough to know the difference between parallel and in series. I also print it off a copy of your wiring diagram.
I most definitely hit the light and subscribe button that's the least I can do for someone who has shared some good knowledge with the world. I am looking forward to watching more of your videos.
Nice to see you getting better tools since I visited your channel last. I do like that the magnet grabs the sworf before it gets a chance to get all over everything. Thanks.
Nice project, great addition to the shop.
Thanks for sharing.
WOW! One of the Best Ideas put to Great use I have ever seen on here! Your version should be mass produced! I dont know how many times I could have used this! Awesome Job!
Love your videos, top quality and easy to follow.
That a awesome idea bravo... can see one of them in my work shed. thank you for the inspiration . :)
It's a great dedicated work you have put in to try something from your imagination. The fine details in the mechanical aspects of the whole job is really amazing.
As far as the surface area of piece to be held is large enough to occupy the pole areas you can guarantee that the force would be great. Anything with a smaller contact area would try to rotate especially when the drill bit tries to pierce through the other side. The torque would be very high to be held up.
Sticking tape to augment the friction is not a good but an inevitable choice.
No need to mention the fact that the electromagnet is to be powered up by an uninterrupted power supply.
The iron filings (though from a soft iron) would be magnetised and would be difficult to clean up for sure.
Thanks for the video.
Just add a sacrifice piec that is long enough to uccupy the pole areas under the small piece.
This is the smartest thing I can think of using electromagnets in the workshop! I also like the idea of the magnetic field pulling down the shavings so much of it does not end up all over the floor/other tools. I gotta build me one of these!
I saw this video some time ago, but I recently came across something that's already made that I think will work well. At a recent visit to a local scrap yard, I noticed that someone had scrapped some parts from a MRI machine. I found some assemblies from somewhere inside the machine. These were 24v electromagnets, and I bought two, and also bought a 24v din rail power supply, that has more than enough current to operate both, with some extra overhead reserve. I'll assemble them in a similar fashion to what you made with your mots. I like the idea of the hole in the senter for the drill bit.
Really nice and professionally designed and built but I saw 2 things you can improve:
1. Use electronic grade potting compound. It doesn't shrink or crack. It doesn't eat up the copper.
2. Shottky diodes are not suitable for inductive flyback clamp. They have a low reverse voltage and are not necessarily fast enough. They are meant for applications where low voltage drop is required, and you don't care about voltage drop in this application. Use a fast switching diode with high reverse voltage. 1N4007 will do.
1N400x are not "fast switching diodes" either. FR400x is a bit better, but nowadays there are tons of choices.
@@inductivethinking You're absolutely right, 1N4xxx are not fast switching. In this case, the communication is done manually by an electromechanical switch and doesn't require fast switching diodes at all. Not sure why I have said that when I wrote the comment. Although fast switching diodes are a better option, almost any diode that can handle an Amp and over 500-600V in reverse will do.
Haven’t pressed play yet. I’m making some popcorn for real because this will be my Saturday guilty pleasure... watching a bad ass dude making cool shit. 😎
So glad you enjoy my videos 😃 thanks for your comment!
Super ! Thank you, Great practical build !
Very good work ! Thank's for sharing !!!
One little tip, you may find if you are wiring in parallel, put your positive and negative end of the coil together for a stronger hold. The electro magnets would be N-S-N S-N-S making it better instead of N-S-N N-S-N which is slightly weaker.
Do the opposite when wiring in series.
I've made the electro magnet from the transformer that you created last time. I'm using it in classes to show the magnetic effect of electricity. I've added a footplate for the apprentices to stand on and some handles thru the transformer holes so that they can pull on it to show their strength or lack of it.
I start out showing how simple it is to disassemble the 2 sections of the electromagnet & challenge them to be stronger than me. The only help I will use will be a UPS 12 Volt battery. Of course once it is powered, there is no way they can pull it apart. It's a great lesson on just how strong an electromagnet can be and just one of the effects of electricity.
Great use of the electromagnets making them into the magnetic vice. Very professional finish as well! 😉
Keep up with the great videos
MiracleMAX
Thanks for sharing your experience! I find it quite amazing how powerful these rather simple electromagnets are. As you've said, it's an excellent example to teach how powerful these forces are. So glad you found my video useful :)
@@Schematix Just like you I am amazed by magnets, both permanent & electo. I have done a video myself on the subject & thoroughly enjoyed the whole process.
Glad you have thrown in your Kiwi sense of humour. It makes learning heaps more fun.
Cheers from across the ditch.
Thanks man this is a great video exactly what i needed, i have this bad habit of forgetting diodes all the time.
Its one of those times i wish i could like a video more than once lol
Brilliant! Just Brilliant!
Awesome, will build one for my workshop real soon
Man I try not to crush on guys doing brilliant things with their hands. It’s a struggle...Great idea and very inspiring. I have so many accessories ideas!Relaxing to watch, Js.You can’t go wrong with a tool I ❤️tools and always appreciated vices ,when you need one it’s the only tool for the job lol.
I love magnets and a lot of other nerdy stuff . Yes Iam a lady and I know I need to be making sammichs, Iam going... Good day
Nice, Thanks for this.
Congratulations on a well thought out design and your craftsmanship.
nice job. I'm in the process of making one. small tip when soldering those banana plugs : tin the wire first, and fill the 'cup' with solder. then while the solder is molten, insert the wire into the cup. The way you did it is unlikely to get much solder into the connection.
That a awesome vidio and will be building one myself. thank you for the inspiration
That was very nice. I could use that magnetic vise on my milling machine. Subbed.
thx for showing preview of a build in the beginning, says a lot about you. subscribing.
A super, very useful idea!.
Brilliant Idea
Very nice ,very clean and a perfect job ,weldone from Israel
Just like a pro!
Very cool project
Danke!
Excellent
I guess I'm on the scrounge for yet another old microwave. Thanks for sharing.
Merci beaucoup pour la vidéo 📼
nice build
It is just perfect
Very nice and handy.
Thats very cool.
Thanks man great vid
The magnet makes good for easy clean up too.
My new favourite channel! Keep up the cool ideas, I can see you going big with these imaginative creations.
Really liked the addition of the grip tape
Skateboard tape would have covered it in 1. Good clip. Surprising he manged to pull the metal off when on. There other clipbs showing 300 kgs?
Thanks a lot my friend, finally an usefull video that explains in details how to proper wire the magnets, excellent job!!!!! With a power supply 12v 10am better connect the 2 magnets in series or parallel?
Thanks!
Good job
thanks for the video
i love this guy
Great vid. way cool
I liked your video. Very well made. I may have to build one of these.
Down hat for your work, really it's the top, my greetings from Algeria 🇩🇿
Congratulations very useful video
Thankyou very useful
I really like the idea of holding metal with magnetism. Keep up the great work too.
Best of 10 videos
Love the video. Thank you for sharing. I have tried 4 power supplies. They are jumping off when turning on and plugged into the coils. I think I may need some kind of load resistor? The last power supply I bought can do 12v and 2 to 30 amp still pops off like it is overloading.
If only i had half his creating talent ! 😄
My first thought was, is this not gonna cost you a ton of power, but 75W for a brief moment isn't so bad.
Well done! 👍🏻😎
75W you could keep turned on 24/7 for a month and not notice the cost (would not recommend though)
For context my area electric costs $ .07 /kWh
You’re looking at $3.75 ish before line transmission costs a month
Awesome bro
Excellent! I'm in the process of collecting a dozen or so microwaves so I can build some of these for various applications. I'd like to incorporate a magnetic panel on my router table spoilboard onto which I can slap metal plates for machining or resurfacing operations.
One question I have is: Is there any advantage to stacking two or more coils onto one "E" section? For example, assuming I have two identical transformers, would it be better to make a magnet out of each like you did here, or could I use the primary coils from each transformer and stack them on one "E" section to make a more powerful magnet in a more compact space? This would eliminate having to mill away so much excess material from the "E" section. I'd be curious to know your thoughts on this idea. Thanks.
Nice Video!
Which values does your power supply actually have?
You could also make another video putting a fence on this so you could make repeatable holes using stops. Nice work. Merry Christmas from Alberta Canada. I wish our PM had balls as big as yours.
Nice video, keep it up, thank you :)
Another great video from a great channel.
Can we please have a video that covers how to determine what amps, volts and perhaps where to source (recycle?) a transformer from.
Thanks.
Great video and project. I may attempt one if I can salvage two microwaves. My question is: Is it necessary to bolt the vise to the metal drill stand? Will the magnetic force above the vise have a complementary force below it that would simultaneously hold the vice in place on the metal drill stand as it holds the workpiece above? This would make it more convenient to move the vice from a drill press to say a metal work table or a pickup truck bed. I might do this for small work pieces that would not overwhelm the vice/magnet. My concern is that the surviving component of the microwaves transformer is U shaped (or W shaped) after you cut it in half. I don't know if the magnetic field lines stay in the metal or leak out as they do above the vice.
Hi @Schematix, You used a resin for the pour. Did you consider using a casting epoxy, which has minimal shrinkage, and if you did, why did you choose Resin?
Very nice work. One question I have is, what amps does it have?
Bravo
Круто я себе тоже сделаю такую приблуду!👍👍👍
Достаточно зазора в 3-4 слоя изоленты и уже ничего примагничиваться не будет! Не вздумайте ничего клеить по верх магнита как автор этого ролика - сила притягивания резко упадёт.
Great video, ? I'm looking to make a Anvil for Golf club steel stamping. Could I put a flat "XX" gauge steel on top of the epoxy (encasing the transformers) then turn the magnet on, sticking the golf club head to steel top than hit a steel stamp with a 2lb hammer as to stamp the golf head?
REAL COOL DUDE !!!!!!!!!!!!!!!!!!
I've made two of these from your design, one for home and one for work. They work fantastically thank you! However now I'm noticing all the tooling I use on the drill becoming magnetised. Would you consider doing a video on how to make a de-magnetiser?
Kup krążek linki #1mm(200mb), Transformator 240/24V 160W i SSR-40 VA 24-380VAC . Cały krążek będzie cewką rozmagnesowującą . Cewkę połącz z uzwojeniem wtórnym trafo poprzez amperomierz AC. W obwód pierwotny trafo wstaw w szereg SSR-40 VA. Reguluj potencjometrem do prądu znamionowego uzwojenia wtórnego trafo . Dla 160W będzie to 6A. Tak obciążony transformator może pracować dość długo. Jeżeli nie wstawisz elementu regulacyjnego to trafo może pracować tylko przez krótki czas, bo je spalisz.
Çok kullanışlı tebrikler.
Always test it before you poor the resin!! ;)
I would have used the mill to flatten the top, flatness is really important for a good grip/connection. ;)
Great work! Congrats!
Please tell me what is the voltage of your power supply. Can we simply remove the secondary coil as you did, keep the primary one and turn it in 127 or 220 AC?
Thank you for your time in advance.
AC wont work as a the magnets will go NSNSNSNSNSNSNS etc. besides mains voltage is dangerous. 2 microwave magnets in series, use 12v 10A DC supply or thereabouts
Witam, świetna robota. Mam pytanie, czy konieczne jest kładzenie tej siatki na uzwojeniach przed zalewaniem żywią i czy ma ona jakieś specjalne zadanie, czy jedynie wzmacniające? Drugie pytanie dotyczy tej taśmy antypoślizgowej. Czy ta taśma antypoślizgowa, którą nakleił pan na wierzchu, to jest jakaś specjalna taśma, czy taka zwykła pierwsza lepsza? Chodzi mi o to, czy kupując jakąś pierwsza lepszą taśmę, nie spowoduję, że zadziała ona być może izolująco , przez co może osłabiać magnesy, pozdrawiam..
Great work, as always :)
Can I ask what CNC machine you have? It looks amazing!
Love your work so much i decided to try this myself! It has not worked out so far lol! Using 2 transformers and a 12v 10amp power supply, but the magnetic power is weak at best. Any tips that might help me figure it out? I am here in Canada and we have 120v lines, could that be the issue? When i turn it on it barely has any pull.
Nice work love the design and execution very well done 👍
I have an upcoming project and would love to incorporate the use of electromagnets
But I may have some questions any input would be greatly appreciated
Keep up the good work
Regards
Biffo
Nice 👍🏻
Great idea. I think I may try this with a couple of electromagnetic door/gate 'locks'. Do you have a rough idea how much current you're pulling?
Great project. Would be nice to have a electro magnet on the bottom so it will stick top you drill table.
What?
Didn't putting the coils in series double the ohms? Did that change the power of the magnet any?
Cutting these down? What if kept full size and the single coils put to top?
Damn that's genius 👏. SUB!
Hello. I used 12 volts and 12.5 currents. It got too hot after 20 minutes of operation. If I lower the current value, would I use it longer? Will I experience a decrease in my usage power? How much current should I use at most?
Are your coils copper will aluminum work as well
Thanks for this education. Question, what purpose does the diode serve in the winging? Only required if adding the LED pilot light?
The diode is essential. It's purpose is to prevent inductive kickback (aka flyback). If you want to learn more on this subject? then watch my inductor video ruclips.net/video/d-E12DlzGGc/видео.html
@@Schematix Reviewing it now. Thanks for the quick response.
Does that diode prevent the power supply from surging/ turning on and off?
Nice video too, I like how descriptive you are.
Cheers
When the power is cut to the electromagnets, all of the energy stored in the magnetic field will result in a voltage spike called flyback which could damage the power supply.
en.wikipedia.org/wiki/Flyback_diode
Do these magnets have an attraction time? How many minutes does it run maximum? Is there any problem in long term studies?
The cover over the connectors is a nice touch. Expect to see that stolen…by me!
Hola amigo lo podria utilizar para sostener extintores y quitarles la valbula
Can you please explain about voltage and amp u didn't mention in digram too
Nice part is you can always apply more power, what kind of duty cycle can you get before it overheats if any? If that's a factor, attach a bimetal to the case to stop power if left on too long, or forget to turn off, always think worst case, it could be destroyed otherwise.
With the current 15v, 5a psu. The vise stays cool to the touch. My theory is, the thermal mass of the vise is reasonably large & can soak up a lot of heat from the coils. Thus far I haven't felt them even get warm. :)
@@Schematix what will happen if you add that hardener to resin and then drink it?
Try it and have your spouse let us know how it went.@@adrianakuzmikova1697
if we change the current direction are we able to float the ion rod?????
What is the Voltage used? Connecting in parallel increases the force also if needed.
it works good with 12v dc
good jod!
Bad ass!
Nice build. Did you also sand the bottom flat? It would propably have been a good idea to mill the top flat on the router after casting the resin. Btw. why didn't you use epoxy resin? It doesn't shrink much at all.
Oh, and one side note: a lot of commercial magnetic vises don't even need electricity, they work purely by moving permanent magnets in and out of alignment with magnetically conductive strips in the surface.
Best answer. Say's it all.
