Hello All:

        There is an excellent gap material available in the U.S., and
probably elsewhere in the world.  These are tungsten contact points made by
Miller Electric Mfg., Co. for their TIG welders.  Their part number is
020-603 if my notes are right.  They cost under $4.00 each.  
        Each electrode is a 1/2 inch diameter by 1.5 inch long steel
cylinder with a 3/8 inch tungsten electrode imbedded in one end.  These work
great for static gaps (5 pairs in series, each gapped to 0.020 inches, with
forced air) and they are good for the stationary part of a rotary spark gap.
One can drill and tap the end to fit a #10 screw, or mount them in a solid
block of aluminum with a set screw to position them.
