Hot glue can be used instead of RTV, It works excellent together with heatshrink. I have done this with success, glue melts when shrinking the tube, and excess is squeezed out. A bit tricky to get the glue in there, but doable. On Fri, Jul 16, 2010 at 7:07 PM, Carl Denk wrote: > I assume that this nneds be weather proof.

Basically, i'm going to have three audio cables (2, 3, and 4 conductors) connected to each other at central location (possibly with a resistor or two between some of the wires). Rather than use a junction box, I was thinking of just potting it. Has anyone done something like this before? I'll need to select a potting material, and figure out something to use for a mold. Any suggestions? Anything else I am overlooking? Does the cable jacket material affect the selection of the potting material? >> >> >> > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- KPL -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
