Step 1): Turn 16 and get license
Step 2): Drive around and pickup old microwave ovens...

What I hate is we had the magnetron in our 1400 Watt oven(household) go bad
a couple of years back and I casually tossed the transformer. This was
before I knew how useful MOTs were. I feel stupid now. Anyways, I'll ask my
dad to keep a lookout for microwave ovens, he does alot of driving for his
job.
