Here is some info i would like to share.....

-Secondary spark gap shape
I have been useing 2 SS bolts for tests, they naturally have blunt ends. So i got 2 more and ground them both to a point (like a pencil).

With the 2 normal bolts the plasma flame seems to to arc out of one spot (its going to be hard to describe) Picture a propane torch that is lit, thats what the plasma flame looks like when it shoots out of the gap.

With the 2 pointed bolts the plasma flame COMPLETELY ENCOMPASSES the gap....360 degrees!!!!! I have burn marks on the bench to prove it...LOL

I have not tried it in the jig yet.....

Of course i have NO WAY to record the event with a camera, but you can see it with your eye! But dont look too long...lol

@tiltfulll:
The engine didnt run because we didnt understand all the variables!

So i will list some variables, so we can conquer them. 

-Their is a certain primary spark gap setting to allow the secondary gap to fire under pressure, i have documented that in a video.
-Chamber size (as you stated, you 100% right)
-Chamber temp
-Secondary spark gap size... the bigger the gap the bigger the event!
-Secondary spark gap shape... Blunt, pointed, or round
-Water amount added
-Water temp
-Water type...tap, well, distilled....ect
-Water type in another form....steam, fog, mist....
-DC voltage
-DC amps
-Chamber pressure at fire
-Spark gap electrode material type
-Cap70 coil turn ratios
-Capacitor size on the primary
-Amount of cold beer on hand 

I am sure their is more.......

As for the primary gap to secondary gap relationship, i took to BRAND NEW plugs, one for primary and one for secondary. Both with stock gap setting, the secondary did not fire under pressure. More tests needed!

Well, i suggest the diode circuit for testing since that gives us less variables!;)
I know that is what I going to do....
I got 40 diode for 14 bucks including shipping!
I hooking up two series of twelve in parallel, that way they maybe last longer.

Also need to get more cold beer    !

Cap70 say's increasing the number of diodes will not help......But you never know till you try for your self...

HV

I thinking that if the lv current can split down beat vine the two set than it maybe works better...

I also thinking of putting the diodes into an oil bath for cooling!
Like an oil cooled pc.
