Barry,
I'll try and answer your questions.

> "Animal grade"?
I use Animal grade Mineral oil, a laxative for farm animals. I got it
at our local farm CO-OP. It was cheap for mineral oil, $25 US for
five US gallons.
> Is that 15 X .006" = .090" of poly between each plate?
Yes thats correct.
> How thick is this capacitor?
Each stack of 21 metal sheets, measures out to 1 7/8". Throw in
the four compressed particle boards, used as spacers and compression
aids, and its overall thickness is about 8".
> Any special preparation to the aluminum edges?
I rounded the corners with a silver dollar and metal shears. And then
used a file and sand paper to smooth the edges. I then washed the
plates in hot soapy water and coated all of them in mineral oil
before stacking them.
