Update on new build parts arrived today ( 7 days to NZ USPS not bad ) so I went to local supplier for the rest seems to be very knowledge ppl ( not fully explaining HHO ) but asked for a drill for SS got a colbolt bit 6 mm NZ$8.96 nylon washers M4x8x(0.

x 200 =NZ$21, M4x40 304 SS screws x16 NZ$12 (ouch ) M4 nuts x 200 NZ$11 and M$x9x(0.

washers x 200 NZ$9 Plus tax on total = about NZ$70 I still need a drill but that is only around NZ$20 so I am hoping after over a hundred spend I can get better results but with washers @ 0.8mm may be to close but then again I can use 2 per spacing of plates which I think is 0.064 inch or 1 washer being 0.032 need some testing here to find the best many rebuilds to come
I am going away this weekend ( waitangi day = New Zealand Day ) so proberly wont start on project until following weekend ( weekend for me is FRI/SAT )
I am hoping to see more accurate results and less plate shorts from tight tolerances
I will keep you posted
Another Idea I have been looking at and posted at the other side was pure water injection with a plasma ignition = your standard coil with low voltage high current ( i.e 100 VDC and 3 ~ 5 A ) across the spark plug and replace the petrol with normal water but there are other problems associated here - but this would be be grand ( whatever ) pull up to the local servo and use their water for your radiator to fill your gas tank go into to say to CSR 2 just filled up my tank with water how much

they look at you and laugh as you leave they say to workmate dumb bugger just put water in petrol tank but it is not far off either it will either be HHO or water/plasma
my finances cant support both at the moment but if HHO does not work out I may just try the other method
