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)...
e-book takes you step-by-step through making a 120cm (4 ft) tall
Parafoil kite. This 4-cell kite performs best in gentle to moderate
wind speeds. That's 12 to 28kph or 8 to 18mph. Even in light
winds, this kite will hang in the air, although at 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 Parafoil 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.
