Right now we're tring to get rid of 27 drums of this because we're
installing gas breakers and getting rid of the oil breakers.  The
way things stand right now it may be disposed of as waste oil 
because salvage won't take it unless they think they can sell it
and they don't.  Talking to a few people I found I may be able 
to work out a deal to get some dirt cheap. (Maybe $10=$20 a drum).
Would you know of anybody interested in 55 gal drums of Shell Diala?
These are sealed, unopened drums that have been in storage about
three years.  Anybody interested would have to pay freight for
about 400 lbs a drum.  We gave six drums of this stuff to a gun
range on base to oil a very large bullet trap and I thought it was
a big waste of some expensive oil, so I figured I'd try to find
somebody who could use it.

I had thought of drilling through the face, but how about this:

Take a 1.5 x 2 inch piece of plexi and glue a .25 x 2 inch 
strip of plexi on to the long sides on one face. Then add
another 1.5 x 2 piece to make a rectangular tube with the
opening an inch wide x the thickness of the plexi. Drill
a 1" hole through the tube between the .25" rails. The faces
of the electrodes will go through each with the gap in the
middle of the tube.

This could be mounted on a plexiglass manifold and would
force all air through the gap.
