Introduction: Singing Tree Rope Runner

design, prototype, waterjet, sandblast, powder coat, and assemble a ascent and descent prototype at tech shop Detroit..  The pulley axles bushings and sheaves were purchased directly from CMI corp.  springs push the upper Rope wrench into the rope causeing it to activate.  pulling up the lower lever arm and clamping it into the rope runner body,  the carabiner

This is not an instructable. It is an Advertisement.

awesome! Let me know when the kickstarter campaign begins, I'll definitely support.

it is a invention ...

rrodefer (author)2013-04-15

Is there somewhere I can get updates on this or other awesome ideas you're coming up with? I am pretty excited to see how this turns out.

rrodefer (author)2013-04-14

I have been using the rope wrench for the past 2 years. Would you say the feel is comparible overall?

kevin bingham (author)rrodefer2013-04-15

Yes, there is much less friction on ascent. The descent is not as intuitive as a hitch but easily figured out with a bit of practice. It is heavier and a bit more kinky than a hitch and rw. Hopefully we cn slim it down without cprising safety. It does the same job as an rw. The biggest advantage is the frictionless ascent

When will I be able to get this? I can not wait to try it out.

josh (author)2013-04-09

looks nifty. How 'bout some instructions on to make our own!

basementhacker (author)2013-03-20 it acts kind of like a gri-gri - locking automatically?

Yes but it does not kink the rope so you can ascend straight up and descend on one device

Love it!!!!

What FEA have you done on this?
What advantages/disadvantages does it have over some of the Petzl/other commercial designs?

Looks interesting but overly complicated. Would really like to read more about it :)

kevin bingham (author)Jayefuu2013-03-25

Petzl does not have any combo ascender/ descender devices. This goes directly up directly down. The closest comparison is the rock exotica unicender which has some usability issues in my opinion

Very, very cool. How do you think it would do in a cave? Would it be able to handle muddy rope?

kevin bingham (author)ar_caver2013-03-24

I think it would work although have not truly tested that. What diameter ropes you use in caving

ar_caver (author)kevin bingham2013-03-24

I have only used 11mm static rope, but I know some use 9mm.

You should do a kickstarter campaign with this!

Working on it! Thanks for the support!

George of the Jungle would love this Gadget !! Thx for share.

This is not an instruct able on how to build a rope runner. It is an instruct able on how to build whatever you like using some of the resources at tech shop

That thing is pretty nifty! Do you plan on making an Instructable about how to make it?

vincent7520 (author)2013-03-21

Hammock empty … with freezing temperatures Jane cannot be there !…

paganwonder (author)2013-03-20

Want one! The tree out back would become a whole new playground!
