[PSUBS-MAILIST] Emer Buoy brake and clear resin

[hank pronk via Personal_Submersibles]

 Jon, I went one step further on my DDW.  I made the smool macho enough to hold 500 feet of super storn 1/2 rope rated for 3,500 lbs or so.  If I release the buoy, it take the rope to the surface and the sub can be hoised up with that rope.  Probably over kill, but why not.Hank

  Thanks Alec, that sounds very similar to what I was envisioning. My spool also has reinforcing ribs on it so sounds like the description you provided will work for me as well.

Hi Jon,

Im not sure whether anyone answered the original question original question about braking the buoy line. I do that, in case I had to release the buoy at a depth that’s much shallower than the length of the line. Since your sub is rated to 600’, I suspect you’re in the same situation.

Shackleton’s buoy line is wound onto a plastic spool that has radial reinforcing ribs on its sides. I think it originally came into my hands when I bought cable. I have a little rotating shaft through the hull. A piece of Kevlar string with a turn on the outboard part of the shaft is attached to a spring-actuated plunger. Initially the buoy is wound in, the little string relaxed, and the spring pushes the plunger into one of the segments on the side of the spool. Rotate the shaft a little, and the plunger is pulled back against its spring, allowing the flotation of the buoy to draw the line out. Rotate the shaft back, and it stops.

Best,
Alec
