[Public-List] Mast up! No halyards~!

[Jeffrey]

Thanks Len,

Yes I really think the prusiks could work. I could use three, one on
each aider (http://www.metoliusclimbing.com/images/4-Step-Aider.jpg)
and one for my harness. I'd be tied to all three. When prusiks slip on
a rope, they slip slowly. I don't know if that would be the case on a
smooth mast. Above the spreaders I'd have no belay at all.

It worked just fine - and we just shook it out to get a second grip with the Prussik, before we had too much pipe out of the hole and had to cut it off before the third pull. 140 feet of pipe comes out real easy when things go well.

If you are worried, take an extra turn or two - as you know, just never allow anything to push on the 'top' of the Prussik ..... and stay ready to do a 'grab & slide' if need be. Strap up to the mast so you don't do an 'end over' and use a belay line over the spreaders.
