This press has worked like a charm for my projects czcams.com/users/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 CZcams 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.
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!
Congratulations on a well thought out design and your craftsmanship.
Nice project, great addition to the shop.
Thanks for sharing.
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!
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.
Love your videos, top quality and easy to follow.
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.
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
That a awesome idea bravo... can see one of them in my work shed. thank you for the inspiration . :)
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.
My new favourite channel! Keep up the cool ideas, I can see you going big with these imaginative creations.
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.
thx for showing preview of a build in the beginning, says a lot about you. subscribing.
Awesome, will build one for my workshop real soon
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!
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
Very good work ! Thank's for sharing !!!
Super ! Thank you, Great practical build !
That was very nice. I could use that magnetic vise on my milling machine. Subbed.
I liked your video. Very well made. I may have to build one of these.
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
Down hat for your work, really it's the top, my greetings from Algeria 🇩🇿
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!
I really like the idea of holding metal with magnetism. Keep up the great work too.
Very nice ,very clean and a perfect job ,weldone from Israel
A super, very useful idea!.
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.
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?
What type band saw blade are you using? Mine starts through and just stops cutting @ 3/8in depth. It doesn't jam it just runs in the groove w/o cutting.
Merci beaucoup pour la vidéo 📼
The magnet makes good for easy clean up too.
Brilliant Idea
Brilliant! Just Brilliant!
Nice, Thanks for this.
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.
I guess I'm on the scrounge for yet another old microwave. Thanks for sharing.
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.
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?
Very cool project
Thanks man great vid
Very nice and handy.
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.
Congratulations very useful video
Just like a pro!
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 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?
Nice Video!
Which values does your power supply actually have?
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.
Best of 10 videos
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.
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..
nice build
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.
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?
Very nice work. One question I have is, what amps does it have?
Excellent
Didn't putting the coils in series double the ohms? Did that change the power of the magnet any?
Great work, as always :)
Can I ask what CNC machine you have? It looks amazing!
It is just perfect
Thats very cool.
Do these magnets have an attraction time? How many minutes does it run maximum? Is there any problem in long term studies?
Would it be possible to put the magnets below the cast iron table and epoxy them there? I think it would be nice if the drill press table could be left as is and hide all of the magical stuff underneath it.
Nice video, keep it up, thank you :)
Good job
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
Thankyou very useful
Great vid. way cool
The cover over the connectors is a nice touch. Expect to see that stolen…by me!
Cutting these down? What if kept full size and the single coils put to top?
Would putting steel below the primary coil and cutting slots make stronger magnet with larger surface area. Any one know if better or no different?
If only i had half his creating talent ! 😄
thanks for the video
Have you used the two windings of the same transformer or two different transformers?
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
Thank for your demonstration of the very professionnel way to do it ----just one question " are you connecting directly on 220V or 110 if you are in US ,because in others video i have seen them using a 12V dc "
What's the reasoning for welding the transformers into the frame (and into the center pipe)? I mean besides wasting some of the energy (force) and messing up the magnetic fields.
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 czcams.com/video/d-E12DlzGGc/video.html
@@Schematix Reviewing it now. Thanks for the quick response.
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.
Anyone have any ideas why my electromagnet pulsates? I am using an AC to DC converter with 120volts AC and the magnetic will turn on and then immediately off and keeps doing this in short bursts. I tried building one just like this but I cannot get it to work correctly. thank you.
REAL COOL DUDE !!!!!!!!!!!!!!!!!!
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. ;)
i love this guy
if we change the current direction are we able to float the ion rod?????
Danke!
In relation the number of coils, would one large coil work as well or better than two coils ?
Would brazing work (maybe aluminum filler)instead of welding for those of use who don’t have a welder?
Ciao hai usato resina poliestere perché la resina epossidica costa di più ...con la poliestere ti sei trovato bene ? Grazie
Other than a great project and very well explained, my only other comment is - sharpen your drill bits.. LOL
Hola amigo lo podria utilizar para sostener extintores y quitarles la valbula
Now to help out the ultimate using a secondary set of magnets to pull all the shavings away for an easier cleanup. Only question is what do you do to clean up wood? 🤔😂
On a more serious note very cool project Amon! Keep up the cool projects bro 👌
Thanks bro! :)
Isn't the magnetic field weakened by the edges and centre all being welded together?
I'm pretty sure the magnetic fields are stronger when the 2 blocks are left independent of each other and you use a plastic tube between them
Can you please explain about voltage and amp u didn't mention in digram too
I think there is a problem. That the metal shavings do not come out easily from the side of the drill due to the magnetism. what is your opinion ? Does magnetism have a negative effect on chip discharge performance or can it be ignored? Please let me know your experience. Thanks for your interesting and practical video.❤
