[PSUBS-MAILIST] Emer Buoy brake and clear resin

[Rick Patton via Personal_Submersibles]

Jon, I advise a braking system for sure. I have a SS 5/8" solid round bar
stock going through 2, O rings as it passes through the hull penetrator.  I
have a small piece of SS flat bar that I can push from the inside
against the aluminum spool that has notches in it so that the flat bar can
grab whatever notch it wants.
As far as the lights, I am running 10,000 LED lights on the outside and I
just built aluminum housings for them with a strain relief fitting for the
power cord to go through. I've tested them to 600' and they were fine. If
one (when one goes bad, I can just take off the faceplate and replace the
bulb without having to throw the whole hosing away.
