Very nice build, door magnets are easy to get, cheap and powerful. I also like the the suggestion of using a heat gun to warm up the parts to be welded, great suggestion there. This will making drilling a lot of holes with a center drill after marking them so much quicker and easy. And it works well in the traditional sense on a surface grinder too. Good stuff, I like!
@@ahill7099 Oh - well you could just put a flat piece of steel on top of the magnet - maybe like 1/4 inch thick as a protector - it would still be magnetic.
I love this build but I want to make a chuck for a surface grinder. Do you think the heat build up would be an issue for the epoxy?..I'm leaning towards yes
@@machinistnick I think I'm going to do it a wee bit different.As knife maker I use heat to separate epoxied parts if I have to so that kind of answers my question. Thanks for the response
Drilling dry? Use penetrating oil. We do. Keeps bit cooler and drills better. But you know that. I'll bet you wanted to keep the piece clean! Right, eh ?

Needs a hole in middle.
Can you specify what you mean by liquid glass resin? Cool build!
It is a 2-component, clear solvent-free epoxy resin.
Very cool build! Noob question though, aren't you afraid of penetrating your cool new electromagnetic holder??
I already made a 20mm hole in the middle in order to avoid injuries.
This is really cool, I'm thinking of making one of these for my 3x72 grinder, do you have a more detailed list on the electronic parts?
Thank you. The main "electronic" parts are 2 door electromagnets, with 280kg force and a 12V 2Amps power supply.
Very cool!
what happens when your drill goes through
You get a spark and the circuit breaker goes off.
@paulsawczyc5019 i just meant wonder i you could have left a lil filler out for drill space

Electromagnetic holding plate.

@@MrPtrvazq I really don't know what to tell you about this. If your grinder has coolant, I guess it will be fine ..

what happens in the event of a power failure? 😬
The power supply capacitors will maintain the magnetic field for 1 to 1.5 seconds. The drill will stop instantly

Use penetrating oil.
We do.

Thaaaaat's not a chuck. A machinist would know that.
It is an electromagnetic chuck
its a magnetic vise
@@ahill7099 No. It is a chuck.
vise. noun. ˈvīs. : any of various tools with two jaws for holding work that close usually by a screw or lever
Nice build but confusing grammar. Drill chucks are devices used to hold a drill or other cutting tools on a spindle. You have made a nice clamp.
@@machinistnick that is definitely not a chuck of any kind
Bad build. No hole in middle.
Great idea )
