Keels 

Try this Kite Winder from Amazon, if you are not sure where to get suitable flying line. The 20 pound strength is ample for all the Skewer Series kites.
The 2-Skewer Dopero - making keels

In this photo, pieces of clear sticky tape are indicated by yellow rectangles.

  • Mark out a triangle on some spare sail plastic, as per the dimensions on the template.
  • Cut off 4 pieces of flying line, each about 1.25SL (36cm, 14") long.
  • Cut out the triangle and tape down 2 lengths of flying line onto one side, as visible in the photo.
  • Now flip the plastic over and tape down another 2 lengths of flying line, directly over the first 2.
  • Also lay down tape along the remaining edge of the keel, on both sides of the plastic.
  • Reinforce the keel corners by sticking down and wrapping extra bits of tape where the pieces of line come out, making sure the plastic remains flat.
  • Where the 4 pieces of line come together, tie a Multi-Strand Simple Knot as close to the plastic as possible, then tie another one further out, as in the photo.
  • Also tie Simple Knots very close to the plastic at the other 2 corners.
  • After all the knots are tied, trim off the line ends to an even length.
  • You have one finished keel. Now do it all again to make the other one!

It's a bit fiddly, but you'll be proud of this kite when you finish it!





How To Build A Dopero Kite
Sail Tethering

The 2-Skewer Dopero - upper sail tethering

At this point you need to make sure the glue is dry on the frame. If it is...

  • Lay down the kite with the bamboo on top, and cut off 2 lengths of flying line of 0.6SL (17cm, 7") each.
  • First, sticky tape the lines to the lower sail near the tips. Lay line over the bamboo, around the sail edge and then back towards the bamboo on the underside - as shown by the yellow rectangles in the photo.
  • Lay the lines across the upper sail and tape them down with just a small square piece of tape near the sail corner.
  • Carefully pull each line through the tape until there is no slack - as in the photo.
  • Add sticky tape to cover the full length of each line on the upper sail.

Note: During test flying in gusty thermal conditions, these lines had a tendency to pull out from the lower sail! Feel free to tie them to the lower horizontal spar instead, using 2 or 3 Half Hitches.





How To Build A Dopero Kite
Bridle

The 2-Skewer Dopero - attaching keels to vertical spars

Firstly, attach a keel to one side...

  • Poke 2 holes in the lower sail, near the lower horizontal spar, where indicated by the black dots near the top of the photo.
  • Take the keel, poke the upper 2 lines through the holes near the horizontal spar, pull tight against the knot, then tie them off around the bamboo using a Granny Knot.
  • Now poke the bottom 2 holes in the plastic, using the keel to find the exact spots for the holes.
  • Thread the lines, pull tight against the knots, and tie them off tightly around the bamboo with a Granny Knot.
  • With the keel flat against the kite, lay clear sticky tape along its base, sticking it to the lower sail plastic. Flip the keel over, and do its other side too - see the yellow rectangle in the photo.
  • All done? Now do the other keel on the other side!

These knots must never come loose, so use tiny drops of glue to keep them secure.

The 2-Skewer Dopero - bridle details

In the original photo, parts of the bridle were very hard to see, so I have colored them pure white.

Attach the upper bridle loop...

  • Lay the kite down with the keel on top, then cut a length of flying line, about 3.0SL (87cm, 35") long
  • Tie a small Loop Knot into each end of the line.
  • Poke 4 holes in the upper sail where indicated by black dots in the photo.
  • Attach each end to a vertical spar through the holes in the upper sail. Use a Double Wrap Slip Knot and pull tight, then secure with a tiny dob of glue.

Now attach the lower bridle loop...

  • Cut off a length of flying line, about 2.0SL (58cm, 23") long.
  • Tie a Loop Knot into each end of the line. Don't make them too small, since...
  • Attach each end to a keel using a Lark's Head Knot, and pull tight against the keel's big knot.

Next, attach the central bridle line...

  • Cut off some flying line, about 2.0SL (58cm, 23") long.
  • Attach one end to the upper bridle loop with a shiftable knot, such as the Prusik.
  • Attach the other end to the lower bridle loop, also with a shiftable knot.
  • Shift each knot to the middle of its loop. Check by suspending the kite from the central line, then tighten both the knots. Don't worry, the knots are still shiftable.

Finally, take a length of flying line about 0.5SL (15cm, 6") long, and tie one end to the central bridle line with another Prusik knot. Tie a small Double Loop Knot into the other end.

At this point, you've pretty much finished making the 2-Skewer Dopero. Whew... But hey, I'm looking at it now, and it's the best skewer kite of the lot!

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.

Testimonials
(unedited)

"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."

Very detailed and USEFUL information - thanks for such a great book."

"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!"
