The most important tool he got is the lathe.

@@ShopperPlug and not a cheap one!

@@josepalacid I’m really saving up to get a nice solid lathe some day. I’m sure it can pay itself later by selling parts made from it.

@@ShopperPlug Sure. But just the fun it's worth it. Then if you can pay it selling parts, that's the perfect world. If you've got that opportunity, go for it!

Yeah, it's really simple presuming that one has a machine shop at hand. Next....he will build a "simple" HeAr laser using "just" a lathe, a mill, a TIG welder, glass blowing equipment,electric measurement tools, and some random stuff he just happened to have laying around.

why specifically the xt30 connector a great idea? clarify

Really right

Yeah, right!

Yes

That’d be sick

@@franciscovilaca900 in a good way, right?

Yes post it on your channel and it would be awesome

@@fortherest8490 yes

Don't u need a conductive surface in order for the magnet to work (i.e. not plastic)?

@@ilikewaffles3689 the magnetic field is generated on demand by the coil to magnetize the steel rod in the middle .... You apply power to the coil ,the coil magnetizes the rod and the rod will stick to metal ..... I only want to print the outer housing

You don't need those things. You just need to try and want to make something. Repeat it thousand times and you will create something working eventually.

Yes he used DC

well I'm no expert so i might be wrong but given what knowledge i have this would not work at all since the whole point of a coil is to make all the wire loop in one direction so that the magnetic fields produced in the wire add constructively and make a much bigger field, however if you used bifilar wound wire then your basically changing the direction of the windings of the coil half way since the current will flow in opposing directions on the 2 parts of the wire, this means that bifilar would basically shoot itself in the foot and kill almost all the magnetism and trifilar might approach, but be inferior to the magnetic pull of a single wound wire loop however if you used bifilar then the self cancelling feature would turn it so that you basically made a gate drive transformer, and a ridiculously big one at that, now you can drive a mosfet the size of a car battery lol

I've had much experience with winding electromagnets. One thing that would improve the power levels on the magnetic field ie the Gauss rating, is to take smaller wire find the total length you'll need to fully wind the bobbin. And divide that length by about 8 to 10 pieces. Solder them each at the ends and then rewind the coil. In my experience I was able to improve the Gauss rating by 350%, and have the resistance down to almost less than 1ohm. If you use a layered steel core compared to a solid steel core that will also improve the electromagnets power levels. It could just be mild steel or Supermendur materials.

Thanks! Turning a spool of polyamide on a lathe takes just a few minutes, the polyamide is processed like plasticine. For 3D printing, there would have to be supports to one flange, subsequent smoothing would take more time

@@maciejnowakprojects or split the spool in half and then glue 🥰

These kind of magnets are highly used in the fabrication industry, to lift heavy steel. Usually controlled by a crane, of some sort.

Thanks! I gave a lot of epoxy there, the wires are practically flooded (not only that they do not touch the housing, it was also a protection against vibration and tearing off)
