[TowerTalk] Cadwelding Copper Flashing (?)

[Paul Henning]

You can indeed do an exothermic weld with flashing. I have never seen a
one-shot to do it however. An exothermic weld using flashing requires a
reusable mold, handles/clamp, and shot charge. The mold I have used is an
erico CRC16002 and a #115 shot charge. Mr. Ron Block did an excellent
grounding presentation at Dayton this year and talked about exothermic
welding copper strap. I enquired later about where to obtain the materials,
his company stocks them! I purchased an entire do it yourself kit from him
which consisted of mold, handles/clamp, igniter, and a quantity of shot
charges. One call resulted in lots of advice and the stuff appearing on my
door step. So my advice is to give Mr. Block a call and avoid the hassle of
finding all the correct pieces. I believe his brother had something to do
with founding PolyPhasor or some such. Mr. Block is a very knowledgeable
resource.

If you use clamps make sure that you remember exactly where you placed them
so you can dig them up and inspect and tighten them at least yearly! What a
pain.....
