Here is an idea for adding this proposed friction channel to an existing ring rather than creating a plate from scratch.
Starting with an aluminum bar of the right size mill or file semicircular grooves on either end of one side so that it nests against the ring.
On the other side grind out a...
I see the similarity. The use of cam-slots to convert longitudinal load into a transverse clamping force (pinching) requires a large and complicated body and introduces metal-on-metal wear points, but it no doubt allows more pressure. With the Sticht Hitch we're getting transverse pressure...
As I experiment with the hardware version of this hitch and observe the way the front and back rings pinch together I wonder if there is a way to use this effect to include additional descending friction within the hitch itself.
If instead of the hole in the middle of the front ring there was a...
I've gone through this thread twice and I cannot find illustrations on how to tie that hardware-free version. The front ring is formed from the hitch cord, not a separate soft ring, correct?
@Brocky you have shown several friction reducing options including various diameters of pipe sections, a second ring, a low friction ring, a Spool Shackle, the Petzl Ultralegere, a ball bearing, pieces of rope mantle, and some I don't recognize. In #270 @Lupin_IV recommended the Pinto spacer...
@moss the two features that caught my eye are
It can be tied mid-line without access to either end of the rope
The exploding release
I don't know how to do the first with a bowline if that is possible. A bowline-on-a-bight requires passing the bight back over the entire knot so I think it is...
Only one post found by search that contains that exact phrase so I may need a bit more help to find the detailed discussions.
As you have innovated in this area, and since apparently the "Maverick" was not part of this discussion unless it already existed by another name, what is your...
If you can travel to see one I assure you being in the path of totality is completely unlike being "near" it, as it's the only way you can actually look at it, and it's spectacular. Spend part of the totality looking through binoculars as the prominences I saw with them are one of my best...
That's very cool. Is anything close to that currently made? How how hard and expensive are these to get?
The minor mishap at 7:20 here is the soft of thing I am hoping people will warn me of. Would attaching a throwline and keeping some tension be a good way to avoid that?
The book gets here...
I wonder what you're implying here. The Sticht Hitch interests me because I would like to eliminate the pulley if I can, and I want a hitch that doesn't bind under full weight if I need to SRT the lanyard without having to de-load the hitch with a Rope Wrench or similar device.
That is not a way I have seen a Stone Knot employed before. I am familiar with its application isolating two strands which would load the knot quite differently I believe. Are you aware of any pull tests on the configuration you show?
I struggle to see how the stopper knot in the middle frame can interfere with the friction hitch as it is well below it. What is the problem with that configuration?
Is not cinching the spine of the bottom carabiner against a 4" stem against manufacturer guidelines for all common carabiners? Plenty strong nevertheless for moderate loads seen in rope ascension or abseiling but this instruction is being given for climbing above the anchor where impact forces...
