Midline Perpendicular Hitch

(1/2) > >>

firebight:
Recently I needed a midline bend for a line perpendicular to the mainline, sorta like a T. I tried several bends like the fig 8 follow thru, and the water knot, but I did not like the way the secondary line exited the mainline knot. I started to play around with a few configurations, what I came up was a midline clove hitch on the mainline and a bulls hitch for the secondary line (See attached images). This worked out fairly well for me, the secondary line exited the mainline knot the way I wanted and it felt pretty secure. Pardon me for the lack of proper terminology here.

What do you think?

The Bull Hitch can jam, so I'd be a little hesitant to use it in this application unless the strains are low.

Every loop knot is essentially a three-way connection, so you can look for some loop knots that can take unusual loading profiles, and can be tied per your scenario.  A Water Bowline form works.

Although in your scenario, you have the added concern of possible rope dissimilarity.

Here are some other options:

If the line gets really slick or springy you could start with a Butterfly Loop and tie to that loop with a Gnat Hitch or Zeppelin Loop.

???  Really, do tell us about this need!

To bend a rope to the middle of another --"middle" implying
that this rope to be loaded on both (or either?!) ends (end)--,
one might try a hitch.  Looking at your solution, you obviously
had sufficient slack in the line tied in its middle (to make a clove).
In which case you might've made an eye-knot and then used
a bight hitch to that eye.

That I'd like to understand your application.  And I'm
in any case skeptical about the use of the clove hitch
--it can be temperamental and jammy.

But I don't think this : especially tied around rope,
there won't be any jamming --too much friction to
overcome!


The (my-named) Janus bowline orginated from a mid-line
attachment, and that seems a reasonable solution for
consideration (again, not knowing the details of use);
just form the nipping loop in the "mid-line" and reeve
the tying-to rope through this loop, collaring one then
the other side/ends of the loop.

As Dan suggested, a description of the application is necessary. There are hundreds of ways to do this.

I was with some friends out for a weekend camp out, and we wanted to make a shade over our picnic table with a tarp. Well, we had a couple trees nearby, so we fashioned one line as the horizontal supports, using other line we made a truss arrangement, sorta like this shape /
Hard to explain. We prefabbed the thing on the ground so there was no tension while making the clove hitches. The images above were taken from home just to show the knot setup we used. Guess it was not as slick as I thought :)

Thanks
