Disassembly of microwave

[danovercash]

Bob just wants to do a post mortem! I like to see into things to see what makes them work too. Some things can be fixed (usually not) and some things can be salvaged, mostly I do it to see what makes them tick. Most recently I cleaned and calabrated two water pump gauges, got the ants out of a light switch, and took the spring out of its cage for a steel tape (had been submerged) cleaned and oiled and put back. Most difficult, but now I have a good 25' Stanley tape. There is a reason they say not to open them! Good luck Bob, but ground that capacitor first, lol!

John, there is no residual radiation in the tube. The radiation is electrically produced, and disappears, as soon as the power is turned off.

May not be on ones made now, but to the best of my memory the ones made 40+ years ago did have, or so they told us at the Litton school I attended. We were warned several times not to do anything that might damage the old magnetron when replacing it. At that time they cost the average person over a weeks wages. By the time any of them failed they were so cheap people just bought new ones rather than paying to get the old ones repaired and we never got to make use of the training.

John, the "do not do anything to damage the tube", is probably because it contained a high vacuum, and could shatter and shower you with glass fragments, like the old cathode ray TV picture tubes. X-ray tubes were constructed that way, also.

These weren't made from glass, they were ceramic, it was not a case of fragile, we were warned not to mess with them.
That does not mean the instructors knew what they were talking about though.

Yesterday, I read this and thought what could you do with a microwave transformer (other than the spot welder mentioned).

Today, I saw on Pinterest where you can take two old microwave transformers, a wet board, and hook some jumper cables to each end and turn on the juice and create interesting burn traces on the board. Hhhhuuuummmm, high voltage electricity, water, and fire on a flammable surface. What could possibly go wrong here.

Yeah, I don't see a problem with that...

I read this one too and was trying to remember either a post I read or a conversation about using a microwave xformer to make a spot welder. Went back to look on Midmo's posts and even his FB page and didn't see anything, so guess he and I were discussing it at the NEOK CubFest earlier this year. That's when Bob and Mike were spotting together those nice battery boxes with Mike's welder.

There's a You Tube by a guy called The King of Random that shows how to make a spot welder. I'll probably save the parts, but it won't be high on my list. Just found a one on one welding class that I'll take next year as I have access to both a plasma cutter and wire feed at the local maker space.

Maybe if you used the transformer and rectifiers you could make a high powered electrolysis tank. Of course it would probably boil dry in a matter of minutes, and if you put something in without turning it off we could add you to the memorial page, or to the Darwin Awards sight.

Well Bob, since you are planning on trying to make 'Something" from some of the microwave parts, I just shipped you an old window AC unit, chest freezer, and a hair dryer. All items "Sort Of Work" but have some type of salvable parts in them. No need to thank me, Merry Xmas.

[Bob McCarty]

Thanks Mike!. I'll be sure and let you know when the box arrives.
