The Slip Knot

And Its Kiting Applications

A small knot in the end of the line prevents this Slip knot from coming undone. At least in theory! In practice, the loop can still loosen off with handling, allowing even a large knot to slip through.

A tiny dob of glue will make the knot permanent after it is first tied and tightened. Alternatively, you can simply check all the knots before each flight, re-tightening where necessary. They are less likely to loosen in-flight.

For a Double Wrap Slip Knot, just wrap the line around the spar twice instead of once, before slipping the Loop knot through. Not surprisingly, this version stays tight a lot longer.

I have used this knot many times for securing bridle lines to spars. If you keep the Loop knot as small as possible, it doesn't look too untidy. It's a good idea to not fix the knots with glue until after the kite has had it's first test flight or 2. Just in case you decide to make any changes!

For a Barn Door kite which stays rigged, this knot can attach the bridle lines to the frame and hold the spars together where they cross. However, I soon discovered that fixing the knots with glue was necessary. The constant flexing of the spars in flight tended to quickly loosen off the knots!

For a time, I experimented with using the single-wrap knot to secure the sail corner ties of the Dowel Roller and Dopero to the horizontal spar. You have no adjustment though, so I'm sticking with Half Hitches now. Not the most secure, but at least you can adjust the length of the tie, if you don't get it right the first time. It's just a matter of unpicking the knot and re-tying.

One last tip... It is simpler and neater to use a Simple knot instead of a Loop to stop the line from pulling through. However, it is not as reliable due to the much smaller size of the knot. It just might be suitable for some applications though!

Now, if you really want to go overboard with knot-tying...

The book Knots: The Complete Visual Guide has an amazing average review score of 5 stars from 12 reviewers - the last time I looked. If it's a more general knot-tying resource you need, this would definitely be it!



E-book special of the month...


I've been flying and posting about the
Dowel Roller recently.

Get the e-book for making this attractive light-to-gentle breeze design.

Substitute a thicker vertical spar and soft Tyvek for plastic, and you have a gentle-to-moderate breeze kite instead.

The e-book is a PDF file - which means printable instructions to refer to while you make the kite. It also means convenient off-line access if that suits you better.

"30+ years ago, I tried making a kite using the 'instructions' in a free kite-safety booklet. What a disappointment for a young boy.

 Your instructions and methods are wonderful. You help the builder to focus on accuracy, without making it hard. Also, you use materials that are durable, yet cheap!"
