Sweating line / 1 man line leveraging

With barely no tools (load, line, anchor) can leverage line more that with a pulley.

Spidy, you are back!!! I was thinking of you this morning, wondering where you have been and how you have been. Update us!!

Good demo....I use sweating a line a lot...learned about it from reading you years ago when you talked about "sweating a purchase" on a line (at least that is the phrase I remember). I probably did it once in awhile then instinctively but never systematically. Once you pointed out how it worked I started trying it regularly. Now, I use it often to tie loads down...secure limbs, equipment in a truck or trailer, etc.

I call it putting the mojo on something. Thanks for the link.

No real stories to tell, just getting along!

Anymore, to me; i only call it sweating a line, if i'm really working at it.
Otherwise, i think of same as just 'dressing' the line; as you look to dress a hitch/ lay the mechanics correctly!

This is mojo; Math mojo!

All the proper setting and tightening on the inline axis; is not the final target, but the setup for leveraging the line.
Like if have 2 matching 3/1 running near each other, and tightened super tight; most would stop there. But instead tighten; tight as possible, to resist bending the rigs; then bend them towards each other. That would be the mojo! Hyper tightening up normally would be just the setup, for the real juice!

Wouldn't think of setting rig as climber without sweating in(just about). Hang on control side of line while bending the load side of line. Tighten up as much first to get most resistance to bend, then bend line going to load. Any line purchase/ length of line sweated out should be held by helping groundies etc. or if self rigging anchor down etc.

Bending flat loaded line, to leverage more tension and 'sweat purchase' out for more load control.
Doing that remotely to RoundTurn, for heavier loads(with less support loading but less shock absorption).

Forces leveraged in line tightening near 90 degrees deflection ( on force calculator) can be high, and tighten directly supporting line.
