I’ve been meaning to build one of these for awhile now… A neighbor got a new microwave so I took their old one for the transformer… It actually only took me about an hour and a half including the box… Here are a couple of the test burns…

Yes, since seeing these I have done quite a bit of reading about the units, and your gator clips look HUGE next to most I have seen. A reason for that, or just what you got your hands on?

What are the 2 cut off lines for red and black?

Also not sure why you have the White lines partially wrapped with what looks like a ground line, and the one doesn’t seem to terminate, just stops mid way, though it is wrapped a bit.

Electrician/Fireman friend says a cut line with no wire nut on it is a fire waiting to happen. Also says a ground starts at one end, and ends at another, yours looks like it’s waiting for a ride.

Not being snarky, or critical, just wondering. I’m educated enough about these things to be dangerous.

That Cedar is ElEcTrIfyInG, careful you don’t get sparked. I’ve seen those fire videos.

Very nice pieces and nice looking set up.
Is that a 600 watt dimmer?

cheers, Jim

The gator clips are huge because they’re actually jumper cables LOL (don’t tell my mother they’re missing from the trunk of her car, I’ll replace them) The ground wire from the power source is terminated to both switches, From the second switch to the transformer it’s just holding the wires together, In all the build videos I watched there is no ground wire going to the transformer, The one gator clip is terminated to the body of the transformer, I didn’t know if there was a reason they don’t connect the ground back to the power source or not.

Probably 600 watts, I just grabbed it off the shelf, It’s only to increase or decrease the 120 volts to the transformer, I don’t know how many watts that transformer draws, I suppose I could probe it while it’s in use and calculate it but unless it fails I’m not going to do that LOL

I bet this could produce at least 1.21 jigawats of electricity….......and that would be enough to make time travel possible.
Test pieces turned out wonderfully.
Well done.

Sweet job, plus looks like it’s as safe as possible too.

Neighbors, I have three dud microwaves here in Hoover, Alabama for the picking! Let me know

Hi MJR. I built two boxes with 600 watt dimmers and they work good for a a small burn. I added a switch to go from the dimmer to full voltage and I’m very happy with them and the results.

I got a note from our Turning guild that the AAW banned any demos or products shown with Fractal Burning. I will continue to take my projects for show and tell anyway!

Be safe…............Cheers, Jim
