My buddy has built HERF guns from WWII search radar magnetrons found at
Fair Radio Sales in Lima, Ohio. Unfortunately, what was almost literally a
dime a dozen twenty years ago is very rare today. He cleaned them out of
all their stock. What they had was stripped of the original magnets - a
good thing, as modern permanent magnets are lots smaller than the Alnico
ones originally used.
We have also made "baby" versions from microwave oven maggies - good for
upwards of 2 KW pulsed power. The search radar parts were good for almost a
megawatt (pulsed).
All of these can fit in a medium sized plastic Sears mechanic's toolbox,
along with twenty minute's worth of batteries. Not exactly a stealthy
thing, but at least portable.

Do you mean the Igor Sikorsky design that was in Popular Mechanics back in
the 1960's? I built a few models, but was never able to get enough thrust
to get them airborne. Pretty good airflow, though, if you don't mind a bit
of ozone...
