Just full of admiration for this guy. Not the artistic ballet like performance of a Clickspring video, but this guy has earned my respect: amazing content (did NOT know it could be done), great and complete instruction, no extraneous BS and blabber, well spoken (and he's ESL) and does amazing things with limited resources - e.g. casting iron on his apartment balcony.

Even Sasquatch might like it lol. I also find most videos tedious, a kernel of content and 100 of blabber, ..... but this guy is awesome!

Yeah I was surprised when I saw this video too. I'd seen glass melting in moulds in microwave but this blew my mind when I saw it.

Nah, susquatch hates everything
 
I obviously know little about microwave principles because I'm pretty sure I fritzed a few with just a bit of tin foil, which made a short lived mini lighting show.
How is it that he can melt a vat of molten iron? I didn't watch preceding episodes, are there modifications or am I missing something fundamental?

It is worth watching his series from the beginning - there are lots of tips and tid-bits in there. But the magic answer is that the silicon carbide crucibles he makes absorb almost all of the microwave energy and convert it to heat, without the energy causing arcing in the metal.
 
Ahhhhh. I saw where he was discussing how to source silicon carbide but missed that detail about absorption. I thought it was related to sustaining high temp of CI. All that action on a condo balcony no less!
 
@PeterT RF things get quite tricky. Any RF engineer will tell you that doing antenna design is a black art outside of the normal configurations. The tin foil is an antenna, and possibly turns into a reflector. Newer microwaves also have changed the waveguide to help protect the magnetron.

I doubt any RF engineer would have tried the metal casting/opal creation things that these hobby guys have done!

I wouldn't recommend to do this, now would I do it myself. But there are a bunch of guys doing this successfully, and that is truly amazing!

I'm glad you said it. That's exactly where I am too. It really is amazing, even mind blowing, and MAYBE it's even ok..... But every neuron in my brain says it's not ok and it's a disaster waiting to happen. Maybe if it became common practice, and maybe if a microwave engineer endorsed it, I'd change my mind. But for the time being, I'm not doing it nor am I blessing it or endorsing it.

No, they are more likely to have fun killing birds with a radar beam. In mid 60's a friend obtained a radar setup out of a CF100. Interesting effects :-) Those were the days when you could get just about anything surplus. Levy Auto Parts at Jane/Weston Rd was an awesome place to roam around.

Heck, I think that your poor deserving wife has earned the right to a new microwave, and you could stand to own a nice heavy 100' extension cord...... Out in the middle of the driveway, aside from potentially melting a hole to Australia, what could possibly go wrong? :rolleyes:
Pictures, don't forget the pictures, video might even be better, depending on which way it goes......:p
 
I remember reading or maybe a video about using a microwave to heat bearings for slip fit on a shaft. Think the bearing was wrapped in a wet towel or something. Sounds like something AVE would come up with, while keeping his d??k in a vise.
 
And if you’re quick enough you can get the tongs, meat mallet and microwave back into the kitchen before your girlfriend notices they’re gone…

Sketchy even by my lax standards.
 
i can't see how a microwave and silicone carbide crucibles is any different in inherent risk than an induction heater.. my issue is more with the lax to nonexistent safety protocols all these fellows employ
