Electromagnetic Drillpress Table! 

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!

Nice work Marsh on the magnetic vise. And the dolly planner was a smart idea too

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.

I've seen this done before but never explained... thank you!

You could have added sand to the second mix of epoxy to get your volume. GE dry transformers are made this way.

Nice!

What a great build! Fantastic idea 💡!

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.

Very clever, even your makeshift surface grinder. , great job , thanks

Great video. Subbed

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 !

I think that if you flip the coils around you can get the windings to the same orientation…

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.

Some cut the e part down to the coil does that make it stronger or leaving it longer make it stronger

Interested to see how the 50/50 holds

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

This is the first time I seen your channel and video. I wonder how well its all holding up if you use it often?

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!

Why not use the primary with your garages supplyed voltage (110/220)?

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

If you want to save on epoxy fill the voids with pebbles or somthing similair.
