[TowerTalk] Grounding System

[Jim McDonald]

I ordered several (17 or so) Cadweld One Shots mail order, and the igniting
power got mixed during shipping with the other powder, and I couldn't get
them to fire with the spark.  I ended up using Cadweld Plus One Shots with
the control unit, which I bought as an "investment" because it worked well
and I wanted it for future use.  I think it's a large capacitor charged by
several AA cells.  As I remember it cost about $100.

I bought the stuff from http://www.therfc.com/ but they no longer sell
Cadwelds.  Local electrical supply houses can probably order them if they
don't stock them.

A Google search will turn up other dealers.

I am getting ready to install the grounding system on my tower. I imagine 
that I will be using Cadweld /ThermoWeld. I wonder if it wil be cost 
effective to use the single shot system rather than buying the 
crucible/mold. Has anyone used this system and can recommend a good place to

purchase this equipment?
