I've only seen one person use it as an inductor, and he did not cut it apar=
t and add a gap. I suppose I'll just go for it, but I only have one, and I =
haven't seen any free microwaves on Craigslist lately. Saw one on the sidew=
alk on my way to work a few weeks ago, but by the time I drove around the b=
lock it was gone. Lotta scroungers out there, I guess :)
Cheers, Bob

Personally, no. But the internet is full of people that have taken out the
secondary windings and wound on 2-3 turns of heavy wire to produce a spot
welder.
Google around a bit on DIY spot welder and I'm sure you find lots of people
hacking up these transformers in interesting ways. Probably something
relevant to be learned there.
