Russ, many thanks for the links to the various sites. I just spent the last
few hours browsing around your site and the related links. Fascinating
reading material. I particularly like the coffee can foundry and the recipe
for making high temperature forge material from perlite available commonly
at garden stores. It really goes to show how things I thought were out of
my reach are doable.
