Hi Kevin,

If you are stuck you can get some small gauge Stainless wire at Home Depot in their hardware section.  They have it so that people can fix exterior fences without the wire corroding in the rain.   I found the gauge, or the steel quality was somewhat low, so I used two pieces twisted together.   It gets hot when you run 3 Amps through it.  dunno the gauge, 20 or 22??    Ravi once mentioned he used copper wire with a HV automotive sealant (you need to confirm)


On a side note, I found that twisted wire connections underwater with this wire could arc over time.   This is bad, but also very cool. The series bifillar coils would cause large voltage spikes across this bad underwater connection and caused underwater arcing.  (with visible light).   HV pulses within the cell appeared to make more gas.  On the scope voltage pulses across the cell went off scale.  I got cautious and rewired my cell.   
The effect of this was a bit like Hyrdrocars'  mechanical pulsing circuit (pre-new-years post) of a DC supply.    I figure it would be hard to recreate this.   
Setup: I drove this with a couple of bench function gen's into a 60 watt audio power amplifier, diode, bifilar to 6x5&1/2" crap welded pipes. 1.8mm gap.

Kevin,

Very well engineered cell.  I look forward to seeing more.

Drill Bit Suggestion:
Use cobalt drill bits and you won't break any more.  They are made for hard stuff like stainless steel and work very well.  They go through stainless like butter.  Harbor Freight carries a set of them for about $50 or you can buy the individual ones at Lowes or Ace.  You can drill about 60 holes before they get dull.  Put pressure on the bit while drilling and drill at a slower rpm.  Also keep your bit cool and it will last a lot longer.  I've got over 100 holes with some of my bits.  I quency mine in cold water while I am using them to keep them from getting to hot.
