Rope Jack

A short 'rough-cut' vid of an DIFFERENT MA technique for pretensioning a rigging rope. It can attach mid-line and can run virtually any length of rope. Certainly not a new idea but one I've been contemplating for some time and finally put a few spare components together today to test the concept ... seems to work well. The MA is approx. 5:1 -- no pulleys, no extra rope, min. weight, min. friction, quick, easy on-off, works well 'topside', too.

Just messin' 'round on a Sunday afternoon ...

I'm using' the "Rope Jack" just for light work! It ain't gonna replace my Maasdam - fo sho. The "Rope Jack" is to remove slack & stretch for lowering and to lift the tips on light limbs without having to break out the big guns.

It is NOT for heavy loads. Cams, even 'untoothed' like a Rescucender and Gibbs, have been shown to shred a rope with high loading. There are much better tools for the heavy work.

The short handle gives a leverage of roughly 5:1 ... I figure the max. I can apply with one hand will be a safe limit for the ascender and to keep from shredding the rope.

One important note about that handle: The handle in the vid is a section of a good quality hickory axe handle ... worked OK. First attempt was with a 1X2 pine board ... it BROKE - I went a**-over-teacup ... sorry no vid of that. LOL

I ain't selling nothin' ... if you want one ... make one ... it's easy ...


Anyway, kinda like the name ... can't imagine why ...
