like the idea of a metal box that can be made ground, others don't. I used
galvanized roof flashing which is easy to cut and bend and I soldered the
seams for an oil tight box. On the top I made a cutout that was fitted with
a Plexiglas cover that was RTVed in place. The tranny was secured in place
and the box was filled with oil. The connections are made through the
Plexiglas with screws that have rubber washers to seal the oil. Maybe I can
get some pictures if anyone is interested.

I have long used a molten, 50-50 mix of paraffin and vaseline to baste and
seal up flat plate capacitors.
