special order bushing for rope wrench

[surveyor]

I find that a shorter wrench works fine and engages faster. Here is my rough prototype in the works.

Apparently there is a RW ZK2 in the pipeline. The race is on!

 

I actually find the length of the RW to be quite useful occasionally when coming in on branch walks. Although I am aware that this may be due to being a beginner and I'm still finding my way with technique.

Zk 2 is the removable pins I believe

[surveyor]

No race, just experiments. I do like the idea of no loose pieces, and that is what I am trying to perfect.

Do you not feel you are ripping the arse out of Kevin's invention a little?

[surveyor]

No, as i have spoken to Kevin and have not been selling them (the Dogbone RW's)to the general public. The sheaves are for any who already have his product.

This arrangement works suprisingly well for me also. both sheaves are free to rotate.

Here is my mid-line designed Dogbone RW (attribution: the rope wrench concept was invented by Kevin Bingham). I had the aluminum frame water cut, and I machined an aluminum sheave at the lower friction point ( a steel or bronze sheave could be used also). It fits snugly on the line and engages quickly due to its short overall length, and weighs in at approx. 5 oz.

I take it you'd use a hitch as well, not just the hitch climber and dog bone wrench?
