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.

I have been using the rope wrench for the past 2 years. Would you say the feel is comparible overall?
kevin bingham (author)  rrodefer2 years ago
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.

looks nifty. How 'bout some instructions on to make our own!
Wait...so it acts kind of like a gri-gri - locking automatically?
kevin bingham (author)  basementhacker2 years ago
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)  Jayefuu2 years ago
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_caver2 years ago
I think it would work although have not truly tested that. What diameter ropes you use in caving
I have only used 11mm static rope, but I know some use 9mm.
You should do a kickstarter campaign with this!

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?
