[PSUBS-MAILIST] Emer Buoy brake and clear resin

[Alan James via Personal_Submersibles]

Jon, regarding the lights; I would run them and see what sort of heat is thrown out front. You could kill them quickly by epoxying them and sealing in the heat; whereas the oil would conduct the heat to the water.

1) Are you braking your spool of rope for the emergency flotation buoy so that it doesn't unravel during normal operations or do you find it unnecessary?  If so, can you describe how you are braking your spool?

2) I'm testing a set of off-the-shelf 12v led lights (4 inch round) and was going to oil compensate them but now I'm thinking about just filling the entire void with a clear non-yellowing epoxy.  I don't see the units as having any useful or serviceable parts upon failure regardless of compensation method so sealing them permanently with epoxy seems like a viable and perhaps less messy method in the long run.  The units would require approximately 1.25 inches (31.75mm) depth of epoxy to fill them and my only concern is what effect the dry epoxy will have on the light emanating from the units.  Any thoughts?


Jon
