RE: Microwave Oven Transformers

Hi RL!  The archives are about the greatest place to find info on MOT's.
Greg Hunter has used MOT's for his TC, which you can see at
www.angelfire-dot-com/ga3/tesla/motpwr.htm

He's really done some good work with them. As for the hv lead connected to
the core, the solution in simple.  Get as identical a MOT as you can
(voltage&current).  Fasten the cores together with a good heavy metal braid
& either the bolts already there (if there are any), or good solder. (tip
from experience, use a small file or sandpaper to get to bare metal on the
laminates, mine all had resin-goop on 'em.)  you need a good electrical
connection.  Hook together the 2 innermost wires on the primary windings.
The outermost wires are your 110v leads.  Hook up a 100watt lamp in series
with 1 side of the 110 (for current limiting)  Throw power to it and attempt
to draw an arc.  If the bulb dims, and no arc, they're out of phase.
Reverse the 110 leads on 1 xformer & try it again.
		Have fun, and beware these little beasties!

Has anyone successfully used MOTs?

They can't be more dangerous than a pole pig!

At 1500 volts each, do you put 8 or ten in series?

What about using two or four and a voltage doubler(s)?

How do you handle the one side of the HV that is usually connected to the
core?
