[TowerTalk] Homebrew Exothermic Mold

[David Gilbert]

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:
