How To Build A Delta Kite
The template shown above represents one side of the kite sail. You will now transfer these measurements to the sail plastic as follows...
Note: I've made the dots much bigger than they need to
be, just so they show up easily in the photo. By the way, there should
be a dot on the center-line, right near the bottom - but the photo cuts
- Firstly, mark the the top dot on the center line, then lay the vertical spar down beside the plastic and mark the bottom dot.
- Measure 1.25SL (36.3cm, 14 3/8") down from the top dot and mark the middle dot.
mark each end of the fold-line plus the mark which is part-way along
the trailing edge, as in the photo - judging the 90 degree angle by eye
is quite OK since any small error will be exactly the same on the other
- Lay a leading-edge spar over the fold-line, and shift the lower dot a little if necessary, so the fold line is exactly the same length as the bamboo spar.
mark the 2 corners of the long narrow flap along the leading edge -
after seeing what 0.05SL (1.5cm, 5/8") looks like, just put these dots
in by eye.
- Finally, rule lines between the marks, as in the photo.
- Flip the plastic bag over, and trace over all the black lines using your marker pen and ruler.
out a roughly rectangular section of the bag containing the kite sail,
open it out and lay it flat on the table - you can now see the complete sail outline, as in the photo.
- Lay a piece of clear sticking tape along the short nose section
with the line showing through the center of the tape - but avoid
getting any tape on the fold-line.
- Lay 4 pieces of clear
sticking tape along the trailing edge, with each line showing through
the center of the tape - again, avoiding the fold-line.
- With scissors, cut all around the sail outline.
Is the glue on all the bamboo spars dry? If so ...
the leading edge spars, the ones with just one short reinforcer, over
the fold lines - with the reinforcers facing the center-line.
one of the remaining spars over the 2 leading edge spars, so it crosses
them at the top end of the 2 reinforcers - this will be the spreader.
- Making sure the spreader is centered over the sail center-line, make marks where it crosses the leading edge spars.
- Next, snip off the ends of the spreader, at those marks
the fit, since you will probably have to snip a few more times to get
it just right - the tips tuck neatly in, with the spreader lying flat against the table.
- When it all looks good, drip on some wood glue, as in the photo.
Now wait for this to dry!
The black pieces of electrical tape mentioned below should all
be roughly 3 times longer than they are wide. You can't see the full
length in the photo since they are folded under.
- Place the remaining spar over the center line of the sail, and underneath the spreader - this is the vertical spar.
the upper end of the vertical spar to the sail with a piece of
electrical tape, wrapping it under to the other side of the sail.
the lower end of the vertical spar to the sail with a similar piece of
electrical tape, wrapping it under to the other side of the sail as
before - gently pull any slackness out of the sail as you do this.
- Next, fold the sail over the leading edge spars and cap the tips with black tape, as in the photo - the tape should be folded around the tip of the spar so it can't slip through the plastic.
- Add more tape like the yellow pieces in the photo - right over top of the short reinforcers.
- Add 4 long pieces of clear sticky tape to complete the taping down of the sail near the leading edges of the kite.
- Secure the spreader to the vertical spar, using drops of glue where they cross.
- If you want to, trim any bits of tape that stick out, with scissors.

E-book special of the month (25% off)...
The Dopero is someone's clever idea to combine 2 Roller kites! Double Pearson Roller is where the name comes from. The resulting flat portion of sail in the middle makes this a very efficient design in light wind.
Even more so than the Roller before it, this kite has an attractive aircraft-like appearance in the air. This MBK version also excels in light winds.
If you have made Diamonds before, this kite takes somewhat more time to make. With the help of my instructions, it's still do-able by a beginner.
Get the e-book for making the MBK Dowel Dopero 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.
This Dopero can fly in quite a wide range of wind speeds thanks to the 4-pont bridle. The bridle lines keep the frame more rigid than a 2-point bridle could. Tail(s) are entirely optional, but may be added for looks.
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.

The huge Multi-Dowel Box took to the air last Saturday, in very gusty fresh winds...
Despite a large field to fly in, the tall trees upwind and the rather low average wind speed down low made launchin…
