A Better Shock Cord Knot? Tips, Part 2



Tie an over hand loop knot in both the Kevlar and elastic cords. The loops should be about 3/4" long. (Left side picture)

Pass the Elastic loop over the Kevlar loop. The elastic loop can pass over the Kevlar knot. (Right side picture)



Pass the loose end of the elastic through the Kevlar loop. (Left side picture)
Pull the end of the elastic almost completely through the Kevlar loop.
Pass the elastic knot and loose end up and through the Kevlar loop.
Pass the Kevlar knot and loose end down and through the elastic loop. (Right side picture)


On the left are the loops after the knots and ends are passed through, before cinching up the knot.

On the right is the finished and tightened knot.
The new knot is cleaner, stronger with less stress on the elastic.

You may not get it right the first time. All new knots take practice.

  1. I tried this, appropriately enough, on the school rocket Claudia bought, after a slight mishap at the NEFAR launch this month. The knot was super easy to tie and does seem like it will distribute the load more evenly across the two materials.
