This is a technician who knows what he's doing. Very impressed.
incredible video. So many great ways to get the job done using common materials. It started really scary when you mentioned using microwave oven transformers, but then switched them into low voltage magnets. Great idea.
The angle grinder on the dolly is genius. Thanks for posting!
What a great build! Fantastic idea 💡!
What a great video Marsh, love love your dolly/grinder and the use of parchment paper in the shop. I’ve been injured in my shop 3 times…..on the damn drill press. Nut behind the wheel as they say. Keep up the good information, and stay well. Thank you.
Nice work Marsh on the magnetic vise. And the dolly planner was a smart idea too
You could have added sand to the second mix of epoxy to get your volume. GE dry transformers are made this way.
Very clever, even your makeshift surface grinder. , great job , thanks
Nice!
Great video and project. Way to upcycle. So many microwaves end up in landfills. Mahalo for sharing! 🙂🐒
thanks I learned what I was looking for.
You good man sir! I liked the fact you give out an idea for those who dont have a milling machine but needed to get it flat enough to be acceptable. I like your video alot. subbed !
Thank you!
If 5V was sufficient to push 25A then you should only need 10V to push 50A. The magnetism is generated by the current, and you only need enough voltage to reach the current limit of your supply. Since you are using DC current you can just measure your coils with an OHM meter and you can use V=IR to determine what voltage supply you need for the desired current. In short, there is no way you need 50V 50A if the 5V 25A worked well.
Hi James, Question - All these amps ! Are the coils gonna get hot and melt the resin ? How do we know how much current the coils are good for ?
@@johnallen8680 50 or even 20 amps is absolute bonkers and will melt the coils in no time !!!!
if you realy want to get good info to make a electromagnetic vise look at th-cam.com/video/DT0QHsN3vcE/w-d-xo.html&ab_channel=Schematix
Great video. Subbed
Some cut the e part down to the coil does that make it stronger or leaving it longer make it stronger
I think that if you flip the coils around you can get the windings to the same orientation…
I've seen this done before but never explained... thank you!
Ps pure badassery, new sub!
If you watch Schmetics you tube he goes over all the details.
Nice job of flattening the top, an unconventional holder for the drill press, but i am sure you will find jobs that it is perfect for. Enjoyed, cheers!
It's been done for a few days and so far I can't imagine a job where I wouldn't use it. Only if the hole is larger than the hole in the mag table.
Interested to see how the 50/50 holds
I’ll post any updates here.
Why not use the primary with your garages supplyed voltage (110/220)?
Everyone else always uses a power supply. I never gave it much thought. I’ll try it.
Awesome project and great results! I have a relatively weird question regarding this electromagnet - do you by any chance know if a magnet like this can achieve sufficient holding power over 40mm distance? For example, if you put a piece of plywood or insulation on top of it and turn it on, does it have any hold? I need something like this for a very specific purpose, but it's very hard to find info on the topic, especially considering that they are mostly used in direct contact. Anything above 10kg of holding force will do for what I need. If you could test this, that would be amazing
When it comes to magnetic fields, 40mm is a LONG way! I have a Nyodinyum magnet with an 800-pound pull and at 40mm it can roll a 2-pound steel ball on a flat surface, but can barely pick up a paperclip.
is there a reason everyone uses all epoxy to fill it? does it need to be homogenous or just not magnetic? I've been planning on making one of these and have been assuming it would be okay to throw scraps of wood in the empty spaces to save on epoxy if i glue them down so they dont float
Someone else mentioned filling it in with pebbles to save epoxy.
This is the first time I seen your channel and video. I wonder how well its all holding up if you use it often?
I use it daily, but it’s a bit of a hassle to keep clean. It magnetizes everything including my drill bits.
@WildmanTech so that being said... is this worth to make and use?
@@mikeklossner5105 fairly certain I'm going to make a float-lock vise. The table magnetizes everything and it's hard to clean. A mechanical mag table would be better, but those don't have a hole for the drill bit to pass into.
If you want to save on epoxy fill the voids with pebbles or somthing similair.
Now you tell me!
@@WildmanTech Sorry you were done and dusted. Seems to be a little excitement on homemade tools, I think your setup is just fine, should you have any problems with sticking when you turn off, which I doubt, you can allways fit a diode in the supply leads to handle the reverse voltage
@@garthdaddy7438 No idea what you’re talking about.
