Theres 80 grams of Copper in every magnetron.

I still haven't found a good way of getting the plates off the ends.
A lathe is defiantly the way to do it though.

I ground the weld off like in the video but the copper absorbs heat like crazy & next thing you are juggling the magnetron from hand to hand. Also the copper 'smears' & fills up the grindstone.



I ground a window thru the weld, then used a cold chisel to part the end off.
The vise kept crushing the copper bobbin & it slipped around a lot, also overstrikes made me cut my hands on the **** sharp stainless steel ends.
Didn't know about the toxic ceramic at the time...

I have over 30 in a box, just waiting for a center lathe.
