[PSUBS-MAILIST] Compass Video

[Alan via Personal_Submersibles]

Jon,
that was one of the most comprehensive "How to" videos I've seen.
Have one of those compasses so will emulate that.
I have reservations about epoxy sealing the wires though.
I did a lot of experiments with glues & PVC wire jackets & found a lot of
the glues disappointing. I found one product specifically for PVC boats
that stood out.
I have mentioned before that I potted a couple of wires for 1" in to a WD40
filled housing & the WD40 just ran out between the epoxy & wire jacket
without pressure. 
Under pressure I would guess that the PVC jacket would be more compressible
than the  epoxy resin around it & would tear away from it, letting water in.
Suggest epoxying the whole board both sides & the wires where they are 
soldered on, in case of water egress.
I have strong reservations about the epoxy sticking to the PVC pipe also.
I would be interested in others opinions on this as potting wires is 
something we are doing a lot of.
