I thought I'd make some soft shackles as a lightweight (and less deadly) alternative to my 3/4" screw pin shackles. There are advantages and disadvantages to soft shackles that I won't address here, but they are another tool in the box. Here we go: 1. Read the articles on L-36.com (a sailing website) at Soft Shackles. This has great info on various soft shackle designs and strengths. One of the articles has a calculator where you enter your rope size and desired shackle diameter and it will tell you how much rope you need. The calculator is based on the "classic" version, which I found overestimated my rope length for my version, but it gets you in the ballpark. 2. Buy some rope. I don't skimp here - 7/16" Sampson Rope AmSteel-Blue Dyneema AS-78 with 24,000 pound average strength. I bought 14 feet from West Marine on sale at $2.90/foot, used for 2 shackles. 3. I followed the instructions on L-36 for "High Strength Soft Shackle" using the button knot. The instructions use two different colored lines to make things easier to follow (this is not an easy knot). I put a piece of masking tape along one end to help me out, and then peeled it off before tightening the knot. 4. I struggled with this knot over and over again, and eventually figured out I was tying it correctly, but tightening it incorrectly. When you tighten the knot you need to keep all 4 strands of line pointing in the same direction. On my first attempts I ended up with lines pointing in different directions. Once I had it right, I set the knot with my Hi-Lift. I did this before tucking the tails (ends) of the knot. 5. The tails of the knot are tucked back inside the rope, which effectively increased the rope diameter in this section. This increases the bending radius of the eye, which improves knot strength (and therefore shackle strength) 6. 7. I bought some 1.14" ID nylon protective hose sleeve on Amazon, doubled it over for 2x thickness, and slipped it on for chafe protection. 8. I ended up making a couple. This version has estimated 230% breaking strength of the 24,000 pound single line, so around 55,000 pounds total. I would not use this for shock loads (snatch straps), but would be great for winch line extensions and other riggings. Cheers.
