Great Meredith!
I appreciate the feedback.  How long were the rod pcs you used?  My own
luck with the EDM carbon is mixed so far.  The big hunk I was given
attracts the magnet -- not so good for this experiment.  But two =BE" sq.
by 1" act just fine =96 they=92re just not big enough for an experiment. =
 I
need to go back to the mold maker and see if he thinks he gave me some
impregnated carbon.   Still haven=92t ordered the carbon rods from
McMaster-Carr.  Maybe tomorrow.  I=91ve also tried to get some bismuth
from a metal dealer, but he hasn=92t called back.  I have a couple more
names to try.  I=92m concerned about getting bismuth shot from Precision
Reloading as the purity/composition is an unknown.
