Mine too !  Thanx for your comments.

Yes, from what I see here the RQ gap seems to be 'the go' & I was
thinking I would build one soon.

No, I didn't.  I just assembled it dry then cased it & added oil. The
oil seeped in noticably over time, & I topped it up a few times.  It
stands vertical in a PE breakfast cereal container (~8.5" x 3" x 11.5"
tall - I can't be bothered giving mm & " , & I figure you guys prefer ")
Again, was in a hurry (ie impatient) & didn't care if this one had a
short life, as I'll be making more.  It runs stone cold, & 'dark', & I
think it's fine. I think the 20x seperate sheets of dielectric helps.

Every little bit helps & I very much appreciate all response - good, bad
or otherwise.

Thanx again, Bob.


P.S. Coil now is unchanged, but has 15kV, 60 mA, & violet 'lightening'
is now about 14" max from the bolt. A torroid & new gap are ASAP
