McMaster also has some excellent "tungsten blanks",
1/4" x 2 1/2" pre-cut cylinders. Excellent
for large RSG. Also they sell 1/2" braided
ground strap which is good for tank connections.
Motor arbors as well for mounting your RSG disc
too and bars of copper/brass etc... for electrode
posts. I could go on forever... the neat thing
is that in wisconsin, I get what I order the very
next day.
