Yes, and I'll get thicker plates as well..

You did pour the oil off the cap-tank before pumping it to vacuum
the second time - and inserted the same oil again after pumping, right?
About the cap-plates..
How meticulously smooth do the ld-pe plates have to be - I got a batch
of .2 mm thick ld-pe plastic for free but it does have little "dents"
because of little particles that were between turns of the roll..
These "dents" are not holes - they are just - well - dents :) Could
I use these "little" damaged sheets?
(This particular brand is "shady" - not completely transparent)
About the x-former oil for the caps..
I found a source for "used" x-former oil - a local company test-uses
their hv x-formers in the oil - then discards this oil - and puts in
fresh oil.. Could the discarded oil be used or will it be too
contaminated - what do you think? This oil would be for free..
Have you ever tried with a spark-gap that has one electrode with a
"pin" at the end and the other "normal" flat-ended electrode.. Someone
posted to sci.electronics about a year ago that he had got better results
with the set-up above than with normal electrodes.. He did say
that two sharp electrodes did not work well at all - which sounds
