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 (25% off)...

Click to get 'Making The MBK Parachute Kite'

This printable e-book takes you step-by-step through making a 119 cm (4 ft) wide Parachute kite. It's not quite that wide in the air since the canopy takes on a distinct curved shape when inflated. This 14-cell kite performs best in moderate to fresh wind speeds. That's 20 to 38 kph or 13 to 24 mph. In gentle winds, this kite will hang in the air at fairly low line angles. In fresh winds, it pulls firmly for it's size, so small kids should only fly it while supervised!

Every kite design in the MBK Soft Series satisfies the following points...

  • Materials are plastic sheet, tape and line – and nothing more!
  • Tools are a ruler, scissors and a marker pen - and nothing more!
  • All cuts are along straight lines.

For the greatest chance of success, I make recommendations regarding the materials. For example, the type/weight of plastic, type/width of tape and line type/strength. Close enough should nearly always be good enough, since the design is well-tested and should be tolerant of small differences from my original.

Get the e-book for making the MBK Parachute kite. After making your first one in plastic and seeing how it performs, you can try soft Tyvek or rip-stop nylon for your next build.

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.

"Love the easy to understand step by step instructions, made from next to nothing materials and above all so much fun to fly... cheers Tim for sharing your well thought out pdf kite designs with the whole world.

Very satisfying making your own and watching them get air-born for the first time."

"I decided to run kite making as an elective again on this camp in the past week - so I bought all your e-books, a bunch of materials, and then took a group of 10 high school students through making the kites over 4 days. We built a diamond, a Barn Door, a Delta, and two skew delta kites. Again - every single kite flew."

"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!"
