View Full Version : T-Splice?
04-27-2007, 06:20 PM
This is for a non-marine application - a sort of climbing net, or rope bridge, of 5/8 nylon 3-strand. The upper and lower main carrying lines will be horizontal, with minor lines running in a sort of vertical zig-zag.
How can I splice the "minor" verticle grid-lines into the "major" horizontal lines, in a T configuration, pulling at a right angle, straight down?
Sort of like:

I have a couple thoughts, but would like to hear your ideas

There was an article in WB not too long ago about making a cargo net. Seems like that would be similar.

Not clear from your question if you intend one or two lower lines. If you use two a crosser's weight will sag the cross lines pulling the lower lines together and making walking impossible.
One lower line and two uppers connected by a network of minor lines clove hitched in place. It's best to use long runs of minor line so you don't have a lot of loose end clove hitches. At any ends, add a taughtline hitch on top of the clove hitch. Run two lines, one from each upper down and back, zigzagging down, having both sides meet at the same place on the lower rope - makes walking easier.
If you have a choise, dacron will be less springy.

What sort of configuration do you intend?
Triangular "footbridge" suspension, vertical footbridge suspension or a cargo-type net?

Cargo Net style , so the net is vertical - one upper line, one lower, with the intermediate squares made of zig-zags (a verticle segment, a horizontal, another verticle...), "spliced" at each intersection (feed line A under one strand of line B, then feed line B under one strand of line A, to make an interlocking X).
But how to join the intermediate lines to upper and lower, where the strain is at a right angle to, rather than in line with, the upper/lower line?
One thought is to make a tight eye splice, running the intermediate line through the upper, around two of the three strands, then back into itself.
Another thought, just splice into the upper, in the direction which will take "most" of the strain.
A third, which I'm not sure how to execute, is to splice into the upper line in BOTH directions.
seize the crossings with small stuff. Simple, straight forward, easily inspected.
