RE: [TCML] Spark gap quandary

["Phil Tuck" <phil@xxxxxxxxxxx>]

Hello,

In the "perfect world" scenario, a correctly sized slot in the rotating disc
would mean erosion of the disc's exiting edge should not happen, as the gap
should have naturally quenched at one of the notches anyway. 
This is like the misconception that an RSG quenches by 'ripping' the arc
apart, which of course it doesn't - or at least shouldn't do, unless you
want power arcing.
Even if the slot was sized 'spot on' though, I would imagine the leading
edge would still get ablated by the heat from the arc, as it makes its
initial passage when the electrodes become uncovered.

Subject: [TCML] Spark gap quandary

Hello all. 
So I was doodling some ideas for a rotary spark gap I am thinking of
building and an idea came to me. 
I envisioned a rotary spark gap utilizing a electrode-less spinning disk
equipped with slots...fashioned in such a way so that the gap could only
fire when the stationary electrodes were aligned with one of the slots.
I'm thinking it could be pretty thin so that the stationary electrodes would
be in close enough proximity that they would naturally arc if there was no
barrier, and that the slots would be inset enough from the edges of the disc
so that the arc could not wrap around the edge of the disk and make a
connection during the break.
Seems like it would make for faster quenching (immediate) and the slots
could perhaps even be variable so that they could be tuned, allowing for a
specific duration of connectedness. (I believe you folks refer to this as
dwell?) No flying electrodes to worry about cleaning or machining into a
form. 
Is it too good to be true?
(I get it named after me if it works...lol)
