This is the Akimbo

Have or do you plan to do any drop testing on the Akimbo? I mean like if a 200 lb. guy fell off a branch and it was shocked at say 4 feet that wasn't tended...that would be a 800# shock wouldn't it? (doubles every 2 feet?)

I believe he is based on possible other Cert ratings it may receive. Some of the shock load is of course also determined by the rope construction itself but if I recall in another thread he made mention of slippage long before that sudden stop.

Sterling rope has already done some preliminary drop testing for me. The results there were that the akimbo slides down the rope a few feet. They did not see any damage to the rope. The amount of slide on a shock load depended on the settings and rope construction. I find those results very encouraging. I've also had one pulled to breaking point at 3500lbs. That test was only in one configuration and RE will be doing more extensive break testing

I have recently been running mine on some 12.5mm sterling workpro, which is very static and quite firm. It has been dreamy to say the least. The combo has changed my outlook on the akimbo. I have been truly enjoying the way it functions, which is awesome because I always thought it looked cool.

Who sells the workpro and is it spliceable?

That thing is shock loaded every time you climb on it Jared. :baaa:

This is totally true a big old corn fed Iowa boy. I did conduct any super scientific standards, just pulled a bunch of hoist testing weights in the shop and pulled it hard When we saw the rope starting to separate we put it down. Now we had akimbo set super tight I am not even sure it would tend either way. All I am saying is the one I cut out of 6061 and 7074 for Jamie was super stout.
 
I am a bit surprised by these "which rope?" questions or comments. I thought one of the clever innovations of this device is that it is so adjustable, most of the rope selection challenges that mechanicals struggle with would be gone.

Not trying to belittle this very cool device...just surprised and trying to understand.

And I will buy one when available too regardless...
 
There are several things that are contributing to these posts looking for the perfect rope. A big one is that most, or maybe all, the Akimos being discussed are prototypes that do not have all the refinements Jamie has developed.
Also, rope will vary widely on how much friction it will produce due to variations in construction and materials. What this all boils down to is, though the Akimbo is easy to adjust and will work on many different ropes, it will work better on some than others. Add that to greatly varying climber weights, climbing styles and conditions, it should not be surprising that different ropes are getting different results by tbe climbers using them.

Also in general an Arborist wants it to function at its optimal output the moment it goes on the rope.
You know it could take days to adjust it to perfection, or we can just ask Frank for the code on "x" rope :whistle:.
We are a relatively impatient breed, as shown by the questions and the number of replies to this thread. Lol
 
The quest for the Holy Grail of mechanical multiscenders, however noble and/or futile, requires that we all pray and make animal sacrifices to the gods of Newtonian Physics and annoy the hell out of the devices' creators with silly questions about rope selection. It is the nature of the universe and mechanical devices, and our pathetic human nature, that this cycle is repeated over and over. Don't fight it... embrace it. Somewhere out there, in the present or perhaps only in the future, a mechanical device and a rope of precisely correct construction and fabrication will meet... in the hands of a climber of precisely the correct weight and skill set... and a booming voice will come down from the heavens, "Dude! That is fucking awesome! Where can I get one?" and there will be much rejoicing.

Or, maybe not. Really, we just don't want to fork up for a device and a new rope without some reassurance that the combination will be absolutely perfect, so we live with the hope that someone else has already done it. And, when it turns out that this mythical perfect combo only works this good if you weigh exactly 156 lbs. and the humidity is exactly 41% and the gravitational pull of Mars is spinning the moons of Jupiter in a counter-clockwise spin... well, then we'll just start the cycle all over, again.

It's all very Zen.
