    Homemade Spot Welder

    That's what I meant by copper to copper only. Even with mine I put thick copper wire inside the copper pipe.

    If you do this, please share pictures.

    I found a neat video. My guess is they are pumping a bit more than 1000W on this one. The sharp edge on the wheel might help.https://youtu.be/ciwXrOtbi3g

    I had thought of trying this as well. I think you could get away with copper sheet wrapped around bearings as long as the contact is copper to copper and doesn't go through the bearing. In terms of strength I recommend playing with the shims. Pull them out completely and you'll likely blow the circuit breaker but you might be able to limit the current with a toaster over or something like that. Maybe one or two pieces of shims would keep the current from swamping the circuit. I have also heard of people using a second shorted MOT as an inductive load as current control. 1000W MOT should work with 1mm steel pieces. Thicker than that and I can offer no promises.

    This is the desk I ended up making and the subsequent improvements.

    It was a gamer PC but I'd recommend staying away from this two headed approach unless you like endless fiddling and configuring. A second sound card is also required if I remember correctly. I ended up abandoning it and buying each of them a refurbished laptop. I set the screens to be an extended display and they were quite happy. I also ended up building a bigger desk but that's another story.

    https://en.wikipedia.org/wiki/Electric_shock#Facto...Read about the dangers here. It sounds like you need at least 42 volts unless you are attaching it directly to your heart tissue. I've never felt even the slightest shock from my welder. Burns are the greater danger. Using welding gloves should protect you from both dangers.
