How to measure 70kv with a spark gap distance:

0.5 cm: 17.0/17.0
1.0 cm: 31.3/31.3
1.5 cm: 44.5/44.8
2.0 cm: 57.0/57.4
2.5 cm: 68.8/69.3

4.5 cm: 99.8/....
5.0 cm: 105.5/....

From A.I.E.E Standards June 1940 as tabled in "Gaseous Conductors", J.D. Cobine, 1958. These are close to the values given in IEEE Std 4-1995 "IEEE Standard Techniques for High-Voltage Testing".

Update:

I brought my electrodes to the company that will plate them with Nickel.
Should get them back next week friday   

I am also getting 70kV out of my coils, already, which is also good progres!

It would be nice if you could re start your Anderson project.
Sofar it is just you and me doing this.

Do you have maybe a suggestion for that oversized SCR ?

Ill gues i just will use a solid state relais for switching of the power to the positive of the cell.....
I found a nice one 1-100vdc and 80 amps SSR. I used them before and they do a good job.

cheers

Kevin, i am happy that we both take different routes. Lets see what works.

In the mean while, i am looking for the propane system of Anderson.
This is what i have sofar:
He used a secondairy regulator model J&S Carb Model 600.
A possible replacement: CLARK 721019 REGULATOR
However, i cannot find sofar the specifications of that replacement part.

The other component of the hydrogen installation is the IMPCO 300 mixer carburator...

The engine was a Ford 351 CID V8.

Something like this one:
