More friction on SRT

[Jim]

Sizzler, thanks. The picture's fine. I may try it a few times on some older line and see what happens.

Actually, it seems that it would work on the same principle as a gri-gri: it bends the line, but doesn't twist it (as with a figure 8).

If so, maybe it wouldn't. Maybe TheTreeSpyder will chip in with some of his insightful wisdom. Hint... Hint...

Ummmmmmmm it operates like a 'sticht' plate. Very nice, non-rope-spiralling friction. But, if maid at waist, and you footlock or cam below to push up it resists going up as well as going down in my experience. Unless you are jsut pulling slack thru from below.

True Blue is a hollow 12 strand, looks a little flattened in picture. No strength loss; in fact less leveraged around curve like that. Not sure about future use of rope if all flattened like that, as far as working around branches (tears up faster), pulleys (doesn't seat right), knots hold differently etc.

if youre saying that my rope looks a little used up, i would have to agree with ya. i think i will be tyring to use the other end more often. i think the problem was that i didnt have a FC until only recently.

Heat, heat, heat.

I think on a rapel of any length the little ring may get hot enough to melt the rope. There needs to be more ability to disapate the heat generated.

Sizzler, I was just askin. I wanted to know which hitch you were usin. Thanks for testin the systems out and posting the info. I'm gonna try the ring next time I do spar chunkin.

The curves look a little tight, Should there be comcern about premature rope wear?

maybe a slightly larger, slightly thicker, aluminum ring for just that reason.

My thought would be to use it in conjunction with a hitch to have two objects over which to spread friction for SRT: the hitch and the ring.

Good point. Attaching it when about to descend would be easy enough.
