That is enough information for me to blueprint from,
the rotary table on the lathe only changes the order
of operations needed to reproduce what I will need.
I'm not in a hurry, I'm still contacting people
about other needs for this prototype project.
I am pretty excited though, I've been given
some very good data to work from already !

I prefer new stainless steel plugs for this,
as I will be using a high heat compound
to bind to them after the bore is plated
with the proper metal for bonding to it.
I'm still going to work on Champion plug a little more
to try and get them to send me a few "Samples" of
their pre-production plug cores that are empty still.
I have four genrators laying around here,
I'll try for those four blanks as "Samples".

I'll bookmark this thread,
and post back in a few months.
I'll let you tell me what part count your comfortable with,
after the "1-off's" to test funtionality, I was hoping on 100.
I'll keep ten, then let others here pay postage
and 1/100th of our costs to get them for themselves
to try their own hand at replicating my prototype.
As a machinist, I perhaps should clarify that
the parts and function for these are simple,
it is the matching electronics that will be the hurdle.
There will be a fuel injector on top,
and a triple electrode chamber too.
So refining the spark start voltage,
the HF current to maintain plasma,
and the timing of the injector pulses.
Will take a few months between all here
to noodle-out in our heads and get right...
Well, that, and the correct material selection needed
to keep injector degradation to a reasonable lifespan.
