Hey, i just made a animation for a dual anode spark plug! So the HV in keep separate then the LV, untill the  tip of the plug, and no need to worry about the cars ground.

This is not my idea, it comes from ATHAL on the waterfuel1978 yahoo group. In the files you can see his PDF. I just went a different way with the insulation material. Carbon fiber should be a lot stronger than broken glass.

have  you  tried  to break the  ceramic  out of a sparkplug?

If it is practical  to break the   ceramic out and a  practical way to  replace it with something else can be found  you may have given me   one of the answers I  have been looking for .


gary.   

Sprocket: dont try it with "multi electrode" plugs, cause you will need to add you own "bird cage" electrode. So dont waste you money, buy cheap-o's!

resonanceman: DOH!!!!!! your right!!!! Please disregard the carbon fiber dual anode plug! 
also...yes i have broken out the insulator in a normal plug... and had just a hollow body... still havent gotten around to even begin to make a dual anode plug yet.... Just a bunch of broken plugs...LOL

as i mentioned...its not my idea! I want to make it fully clear that its ATHAL's idea from waterfuel1978 group! He has already made a prototype for it, its all in the PDF in his folder in the files section. I just thought it would be better to presss tubing in to the body rather than make the insulator out of used bulbs, like ATHAL had done.

EDIT: Sprocket...here is a idea for the "bird cage" ground electrode.

resonanceman: i was also looking into "cold-casting porcelain" ... it would seem that you take 1/3 epoxy, 1/3 hardener, and 1/3 porcelain dust (by weight). I am looking for a epoxy that will withstand the heat and the pressure.

I am thinking  of  procelain   or  a similar  ceramic    .

Anyone here  have any  experience   with a  HHO torch?
I have heard that they can  burn a hole in  firebrick ........and  weld  metal to things like brick .
It seems to me that  with a jig  that spins  the  plug at a few RPM    a water   torch  could   seal  the  ends of  the plug  pretty efficently   if the  right materials  are used .

I think it is  a great concept .....just  needs a little work  on the  materials .

Unless there has been some pretty big advances in  epoxy  I don't think you  will find  one that  can take that kind of heat . 


I  am wondering  about  using something  like  ( if  I remember right )   sodium  silacate ...... it  used to be called waterglass
It  used to  be used for sealing packages .  I   also  read how it could be used to repair  chips in  glassware
Repairing chipped  glass   required a torch .......but not near enough heat to  melt the glass
