Well I found an easy way to make a portable MOT supply. Instead of putting 
all the MOT's into one big heavy container with oil I put each one in it's 
own container with oil. I only am using 4 MOT's but it should work with more 
and is much easier to transport than a pole pig weighing a couple hundred 
pounds. Large coffee cans can fit most MOT's and so long as you use some 
strong glue to seal the lid and the spots where connection wires come through 
it shouldn't leak. All you need to pay for is some transformer oil which I 
got for less than $7 a gallon and you won't need more than 5 gallons.

 Say you wnt around 15kV from 2kV transformers. That's a string of 7. If you
 ground the center, you still have 7kV across the primary windings to the
 output on the "outer" two transfomers. It seems some insulate them with oil,
 which is really messy and does not sounds too portable.
