I wanted to make several Cadweld-type connections (#4 copper wire to 5/8
inch ground rod) for my tower ground system, and I since I had already
obtained a bunch of the weld metal powder on eBay I wanted to use a
standard graphite mold instead of buying a bunch of One-Shots. Not
knowing my way around the industrial websites (and not wanting to set up
a commercial account just for that purpose) I decided to try to
fabricate my own mold. The result may look a bit clumsy but it works.
For the non-squeamish, details can be viewed at:
