Tony,
3M makes a two part resin casting kit for splicing cables together.
Whiletailored for round cable, it works well with anything. I've remade
rubbermallet heads, made custom feet for heavy amplifiers or power supplies,as
well as used it for its intended purpose. The resin is called ScotchcastBrand
2130 and usually comes in a brown cardboard field kit. For equipmentor outside
use its designed for direct burial and is rated for 1KV to 5KVdepending upon
how much copper you are potting.
I repair audio and video snakes and also submersible sonar cables in myspare
time and use this resin often. Done correctly, the joint is strongerthan the
cabling. Cure time is a couple of hours before handling, 24 hoursfor full
strength. The 82-F1 kit handles cable from .25" to .80" and the82-F2 kit can
do larger cables in the .8" to 1.2" range. There are many kitswith many
different mold configurations such as Y's and breakouts.
You can Google for instructions, examples, how to use, etc. and you shouldfind
plenty of information on it. 3M used to sell a 3 1/2 oz. A/B portapack butI
don't know if they still have this. I do mostly 1/2" cables and use the 7 oz.
A/B pack which leaves me 2 oz or so extra which I take and finish off on
somepersonal repair or custom mold.
Anyway, something to keep in mind. I put a few things up on my web foryou to
see. A "typical" data sheet is at:
