Hitch Hiker to Twisted Clevis

I was thinking of getting a 3/8 inch Wichard Locking twisted Clevis to attach the bottom of the Hitch Hiker to a swivel on the bridge.

In other threads, people have successfully used 1/2 inch shackles for their bottom attachment point on the HH, would reducing the size to 3/8 inch make much of a difference?

I'm thinking the twist will create a perfect upper and lower point of attachment for the neck bungee/knee ascender.

Any thoughts?
 
YoYo, I remember your first post with the shackle, so you could use the HH on a zip line. I know the shape of the caribiner changes the operation of the HH if the body is horizontal and the 'biner is vertical, hence the shackle. This makes me think that the fixie pulley addition at the bridge connection would be great for you, since the 'biner will stay horizontal.

A photo is posted in the HH Carabiner thread...bottom of page 1. You must have seen it.
 
Am liking the HH bow shackle / swivel combo.
Very consistent, and tends nice.

Looks like you guys are getting it dialed in. I like David's idea with the Swiva-biner. I gotta say, either way, having a pulley makes the HH so much better.

I took a couple of screen shots from the video.

This is by far the sweetest configuration I have used but it will be met with controversy. The Pinto pulley makes tending and setting up a 3:1 MA for ascent or limbwalk return a breeze. It would also work well with the swivel biner. I use an elastic neck lanyard to tend and that Pinto snugs up to the base of the HH like it was designed that way with very minimal setback.

The controversy: I took a rated shackle, about 9,000 pounds and shaved off just enough from the eye where the pin connects to get it to fit into the eye of the Pinto pulley. The shackle probably went from 9 to 8,000 pound rating but I did not test it and of course will not recommend it.
The shackle is the way to go on the HH and if I were serious about it I would take that modified shackle and get it tested. For me I am as confident in the modified shackle as I am in any branch I put my rope over.

I've been thinking that if Rock Exotica were to collaborated with Rope Tek to create a shackle swivel with built in mini pulley using the shackle pin as the axel for the pulley. With a rated Beckett that was perpendicular to the swivel and parallel to the pulley. The Hitch Hiker would be complete and an even more invaluable tool. Times like this I wish I knew how to doodle on the computer and add them to the buzz. Damn you computer illiteracy. Hope y'all get what I'm describing, maybe one of you more advanced buzzer could give me a hand!

what size shackle are you using and where did you purchase it as that looks like a sweet setup.

It IS sweet, my problem is putting this public, I modified a manufactured product and don't feel comfortable posting that info. I know I do it all the time and modify many things and use some unconventional ideas and post the info but this time I don't feel comfortable posting the specifics. I have posted the info on the 1/2 shackle.

Send me a PM and I'll give you what I know and take no responsibility for your actions.
 
Yoyo thanks for taking the wind from my sails! IF is sometimes an awfully wishful word. I do appreciate all of the clever conversions you have made to the Hitch Hiker and various other equipment. Having never used a Unicender I did not take into consideration that Rock Exotica already has it's own "fish to fry" with improvments on the Uni.
 
Quick question YoYo....would an ISC fixed Pully work in place of the Pinto in your opinion. I'm not sure if the size/shape will have a big impact on how smooth it runs.

I love your set up but looks like a lot of stuff after you clip that biner to the dmm ring on my bridge. I think your setup, but with the swivabiner sounds epic (Just to tidy up a bit).

Thanks for the pictures
 
Yes, Dave has a great idea with the swivel biner. I'm not home but I think the ISC fixed Pulley has the same diameter eye holes and should work fine, the Hitch Climber pulley also has the same diameter eye holes.
Another option is to put the swivel directly on your rope bridge if you are using one especially if you are using an adjustable bridge like Tom D uses, that would be nice!
 
Hi Richard - wondering if the side plates on your pinto pulley are getting mangled against the steel edges of the HH?
I doubt you weakened the shackle significantly, but for your setup, would enlarging the hole on the Pinto (cringe at the notion of actually doing that) be possibly a safer option than shaving down the shackle legs?
 
YoYo, I totally see the virtue in your setup, I just still don't see why you don't set it up with a biner between the HH and the Pinto, and use a swivel directly on your bridge. The only thing I can gather from what I've seen is that you can disconnect it without any drop hazard, as it all stays together in one unit. Conversely, if you wanted to take it off the line, isn't the shackle more to muck with than a biner? I guess that may just be chalked up to my perspective from a production environment. Whatever works best for YOU is what you should do, so keep up the ideas, brother.

Oceans, so you are basically asking what are the virtues of the shackle vs. biner.
Here are some:
The pin of the shackle is round and the orientation of the shackle does not change the profile of the contact with the rope. The biner is not only curved but also simi flat on the sides, every time the biner moves the shape that is contacting the rope changes, this impacts the friction and function, binding, doing traverses the shape of the biner can go from the flat side to the curved side and is also exasperated by the curvature of the biner.

A round pin (the shackle is smooth and consistent)

For the smaller shackle it is much lighter.

The shackle always stays oriented.

The shackle is easier to tend.

The pin is round and sits nicely on the plates of the HH without scaring. Thus the frame could be aluminum.

I'm probably missing some but the point is that that friction surface needs to be round just like the dogbone.

Here are a few other ideas to kick around. It actually works pretty well and again leaves a round consistent shape to contact the climbing line.

Hey Dave, I thought I answered but guess my post didn't get finished.
Because there is not much weight on the pinto when it makes contact it does not get damaged or scared up too much. Yea, don't think I want to make that whole bigger on the Pinto, besides I use if for other things, the shackle only goes on the HH.
