Re: [TCML] DC SGTC charging inductor

Hey David,
I found a couple of old oil furnaces at a customer's business. Can I put those ignitors to good use? 

Thanks,
Jim

I got one or two the first couple of weeks and then the torrent opened up
and I got 30 the next month.  These advertisements take time to percolate.

Hey Fred -- you know that junker microwave you have in your garage? Well, I
just saw this ad...

There are a lot of other cool things to salvage -- some of the interiors are
stainless steel (generally older units), there are some heating elements,
relays, microswitches, small motors, fans. Lots of good stuff for free.
Usually, it's the "brains" that stop working -- most everything else is just
fine. A lot of the ovens use 'security' screws to prevent the casual home
owner from breaking into where the lethal voltages are.  You can get a set
of driver bits from Harbor Freight:

http://www.harborfreight.com/100-piece-security-bit-set-68457.html

On sale now for just under ten bucks and you will use it on a lot of other
stuff in the future (it has a lot of standard driver bits as well as the
security bits).

I picked up a lot of my MOs between craigslist and freecycle, with a
dozen or so from the local MO repair shop (when such a thing actually
existed).  If you post a wanted ad for "Microwaves: dead or
alive", you
will find yourself with a ready supply within a reasonable
amount of time.

I posted an ad (under the appliances heading) for a couple

months and wound

up getting about 40 dead ovens.

Also, I never followed through with this but you might also

want to check

with local hotels and motels. They generally have a

microwave in each room.

Explain to the manager that you are a starving student and

need to use these

for a "science project" and see what happens.

Speak for yourself, Tesla  ;o)

Around here, the local waste transfer station won't let me take old
microwaves any more, 'cause they say that their scrap value is too
high.  Only time I can snag an old MWO is if I see one that
someone has
left illegally at the curb on trash day, and even then, they
don't last
long.

On top of that, the newest ovens use high frequency solid
state inverter
circuitry and a small coil resembling a glorified TV flyback
transformer
instead of the old big iron MOTs.  Utterly useless for TC
applications.
