| I often find it helpful to work with compartments within the knot. Overs and unders don't matter for the concept of compartments. In the grid I have randomly labelled some compartments. For example, "C2" is the compartment which has 2 parts of cord to the nearest edge. Similarly, "C1" has only 1 part to the nearest edge. "CC" is the centre compartment which has an equal number of parts to both edges, in this case 3. |
Anyone who has tied ABOK#3054 will know that it is a bit of a monster!
This tutorial shows an alternative, much simpler, knot that bears a reasonable
resemblance to Ashley's excellent knot which is one of my favourites.
The photo
shows a 9 part *17 bight common grommet that follows a Turks Head path
throughout.
Working from left to right, go over all on the way down and under
all on the way up.
It will help if you have read Jim Caswell's Fine article in
KM#85.
The mandrel has diameter 65mm. and the distance between the pin rows is
42mm.
The graph paper helps with pin spacing and the pin colours have no
significance.
The cord is 2mm.Colourline.
With the red cord, starting at the top and working from left to right,
enter at the top from outside the knot and come at C2 at the bottom as shown.
Notice that red is parallel with two upper blues.
Enter at the next C2 on the right ( go over the cross ) and go up
U2,O1,U2. Stay in the channel defined by two lower blues. You will have come
out at C2 at the top.
Over the cross into the next C2, down under all and out at C2 at the
bottom as shown.
As before U2,O1,U2 on the way up.
Over the
cross into next C2, down under all and come up at C2 under the neighbouring red
bight . Notice that blue has right-hand lay. Red will have left-hand lay. With
regard to red, over all red parts on the way up and under all red parts on the
way down.
Over the
red bight at the top for left-hand lay.
Under all
on the way down.
Finally,
come down alongside the standing part and come out of the knot at the bottom.
Don't cross over the standing part.
Finished
with red.
Do the
same with blue.
The knot
is now formed. It is simply two interwoven common grommets, one left-hand lay
and the other right -hand lay. Pin the occasional red part around the middle so
as to keep control of the knot while removing the slack and remove all other
pins.
Remove
the initial slack from blue and remove the centre pins.
This
shows the slack taken out of red.
Here the
knot has been moved to another mandrel with diameter 42mm., a little bigger
than its final resting place!
This
shows the initial slack removed again.
This is
the finished knot on a 38mm. diameter plastic pipe.
The knot can be made with any number of bights except multiples of both 3 and 7.
I hope you enjoy making this knot.

This is
the same knot in one colour.
Side
view. My own preference is one colour for this knot.
Here is
the start of an alternative version. It has 17 parts, 10 blue and 7 purple.
On
the way up with purple it is U2,O2,U2.
On the
way down, go under 5 lower diagonals and 1 upper diagonal as shown.
You should
manage with just these two photos.
This is the 17 part version around the edge of a circular board.
