How To Make A Diamond Kite
Complete Instructions For The MBK Dowel Diamond Kite
This set of instructions on how to make a Diamond kite assumes you know absolutely nothing about kite making. You might already have some
of the simple tools and materials required. Anything you don't have is
easily bought. If not exactly what I used, then at least something
The instructions on how to make a Diamond kite might look awfully long,
but that's because they are so detailed. For those who like pictures,
every detail is illustrated with photographs too. Just quickly work
your way through from top to bottom, skimming over any detail that you
The MBK Dowel Diamond Kite is a large tail-less
Diamond, inspired by the famous Eddy design. The Dowel Diamond is a
good light-to-moderate wind flier and can cope with moderately gusty
and fresh winds. The kite is designed to roll up into a slim
cylindrical package like a Sled, thanks to the 2 detachable corners of
the sail and the toggle-linked bow line. Setting up on the flying field
takes just a minute or 2. Of course, if you have room, you can always
leave this Diamond ready-to-fly!
Now's the time to read up on the kite making tools and materials required for making a Dowel Diamond, if you haven't already.
If kiting knots are a mystery to you, then it's also a great time to look at some knot tying instructions for MBK kites!
How To Make A Diamond Kite - Spars
this diamond, you need 3 lengths of 6mm wooden dowel. I have chosen to
make '1 Dowel Length' equal to 1.2 meters since that just lets the
vertical spar fit the garden bags we buy. If you are in North America,
4 feet of 1/4" dowel might be a good choice!
- From a long piece of dowel, cut off lengths of 1.0DL, 0.94DL and 0.02DL with the hack-saw. Yes, that last one is very short!
- Round off the 2 tips of each length with your wood file.
a line around the exact center-point of the longest dowel with the
marker pen. Also mark a little 'H' on it somewhere, since this is your horizontal spar.
- Mark a line around the slightly shorter dowel, 0.14DL from one end. Also mark a little 'V' on it somewhere, since this is your vertical spar.
How To Make A Diamond Kite - Sail
The template shown above represents one side of the kite sail. You will now transfer these measurements to the sail plastic as follows...
- Firstly, take a large bag that will fit the entire Template shape within one side, and lay it flat on the floor.
the vertical spar down beside the left crease of the bag, and mark dots
corresponding to the top and bottom of the Template. Also mark a dot
corresponding to the mark you made near the top of the dowel. This is
where the spars cross.
- Lay down the horizontal spar as in the
photo, hence mark a dot on the plastic at the tip of the dowel. I have
highlighted the corners of the sail in yellow since the marker pen
lines and dots are a bit hard to see. There is no need to use a
T-square, since any small error will be duplicated on the other side of
- Using the marking pen, rule lines between the dots.
For lines longer than the ruler, just add a few extra dots using one of
the dowel spars as a ruler! Then it's easy to connect the dots. It's
probably best not to rule the whole line with the dowel, since it bends easily.
- Flip the plastic bag over, and trace over all the black lines using your marker pen and ruler.
out a rectangular section of the bag containing the kite sail, open it
out and lay it flat on the floor - you can now see the complete sail outline, as in the photo. As before, the lines are hard to see so I have added yellow dots at the corners.
When doing the following, most of the width of the tape should be inside
the kite's outline. Use a single length of tape for each line. Hold it
out straight, touch it down to the plastic at one end, then at the
other end, dab it down in the middle, then press down all along its
- Lay clear sticking tape along all the lines, letting it overlap at the corners.
- With scissors, cut along all the black lines. This will leave most of the width of the sticking tape inside the sail outline.
How To Make A Diamond Kite - Spars And Sail Attachment
vertical spar will have an insulation tape tie attached to it, which
will be used to lash the 2 spars together before flying. Also, it has 2
marks which show where the bridle lines attach. Here's how to do all
that, starting with the marks...
- Measure 0.1DL in from the top end and mark around the spar with the black marker.
- Go to the other end of the dowel and measure in 0.3DL. Again, draw a line around the spar.
- Measure and cut off a 0.2DL length of insulation tape. Fold it in thirds, length-wise so it looks long and thin, with all the stickiness inside.
and cut off another length of tape that is long enough to go all the
way around the dowel, plus a little more. Cut it in half, in the length-wise direction, so its width is halved. It's the red tape in the photo.
the tape at the spar-crossing point which is already marked on the
dowel at 0.14DL from the tip, not far from where you made the bridle
mark. The red tape is on the bottom. It wraps around the dowel,
attaching the longer folded tape to the dowel.
- Prepare 6 lengths of electrical insulation tape,
each one about 4 times longer than it is wide. Stick them by a corner
onto something handy like a table edge. You can remove them one at a
time as needed.
- Lay down the vertical spar, lining it up with
the top and bottom corners of the diamond. Also, the long tape tie
needs to be on the bottom, against the plastic sail.
- Cap the top end of the spar with tape, as in the top
photo, by sticking it down over the dowel and plastic then folding it
under the plastic to stick on the other side - a bit tricky, take your
- For added strength, put another piece of tape across the cap, folding the corners around and under the sail plastic.
- Do the bottom end of the spar similarly, using 2 more pieces of tape.
- Finally, add the last 2 pieces of tape just above and below the tape tie, as in the bottom photo. Actually, place them a little further apart - I had trouble feeding the tie between the dowel and the plastic, and had to make slits in the plastic!
Now there's a little work to be done on the horizontal spar. Use 50 pound flying line, either nylon or polyester (Dacron) for the bow line.
While waiting for those drops of glue to dry on the knots, it's time to add corner straps to the left and right wing-tips of the sail.
How To Make A Diamond Kite - Bridle
- Turn the plastic over so the vertical spar lies against the floor.
- Look for the mark near the top of the spar, and poke 2 small holes in the plastic, one on either side of the mark.
- Look for the mark near the bottom of the spar, and poke another 2 small holes in the plastic in the same way.
- Cut off 2DL of 50 pound flying line.
- Tie a Simple Overhand Loop into each end. Make them as small as possible, since the loops aren't being used, just the knots!
one end through a hole near the top of the spar, around the spar, and
out through the other near-by hole in the plastic. Tuck the loop knot
through and pull tight against the plastic to form a Single Wrap Slip
Knot. There it is in the photo.
- Do similarly with the other end
of the line at the bottom end of the dowel. You now have a bridle loop
attached to the kite. I have added black dots to show where the holes
Finally, take a length of flying line about 0.2DL
long, and tie one end to the bridle line with a Prusik knot. Tie a
small Double Overhand Loop into the other end, just to get a large
knot. There's a photo of this further down, in the section titled Before The First Flight.
this point, you've pretty much finished making the Dowel Diamond!

loop on the other line. I find it handy to pin the middle of the spar
to the ground with a foot.

down the bowed horizontal spar, so its tips are near the wing-tips of
the sail. Fasten it to the vertical spar with the tie. Weave the tie
over and under the spars, all the way around the cross-over point. You
should have enough length over to tie it off with a Granny Knot. Bear
in mind that you have to be able to un-pick this knot after flying! Hence don't pull it too tight. See the top photo, which also shows the toggled bow-line.
one corner strap, locate the spar tip in it and pull just a little
tension into the sail plastic. Feed the strap around the bow-line, and
then wrap it around itself, back towards the tip of the spar. See the bottom photo.
- Go to the other tip and do the same thing, pulling in about the same amount of tension into the sail.

Make up a flying line and attach it to the bridle with a Lark's Head knot. See the photo over there, where the Lark's Head has been left loose.
the kite from the Double Loop Knot. Shift the Prusik Knot along the
bridle line until the kite hangs at around a 20 degree angle from the
horizontal. To lock the Prusik in place, take the 2 bridle lines in one
hand, the flying line in the other, and pull tight. To unlock it, you
just pull the bridle line straight, with the knot in the middle.
the bridle slip knots on the vertical spar. Re-tighten if necessary,
and put a small drop of wood glue on each so they can never come loose.
Turn the kite over and also put a small drop of glue on the wood to
ensure the knots don't slip up or down the spar.
How To Make A Diamond Kite - Flying!
Firstly, if it's very windy
outside, stay home! This is a light-wind kite and won't like being
launched in a gale. If the wind is too strong, it might not even be
stable enough to fly.
Prusik knot on the bridle line can loosen off a little over time. If
necessary, pull on all the lines to tighten the knot up before a flying
Assuming there is some breeze outside, just
dangle the kite at arm's length until the wind catches it. As long as
you feel the kite pulling, let out line slowly by taking loop after
loop off the winder. Be cautious about letting line slip through your
fingers. If a big gust hits the kite, the line could burn you! For any
kite this big or bigger, it's a good idea to wear a glove of some sort.
approach is to get a helper to hold the kite up and let it go, on the
end of maybe 10 or 20 meters of line. This way, the kite soon gets high
enough to make it easy to let more line out.
In the launch picture over there, there's a distant Magpie near the wingtip and a White Cockatoo much nearer, center left.
The Dowel Diamond Kite eBook is a neat compilation of all the info on this page and much more.
Have fun flying, and I hope you've enjoyed learning how to make a Diamond kite.
How To Make A Diamond Kite - Breaking Down
don't mean breaking down in grief because your flying session has come
to an end - I mean getting the kite packed up ready for transport or
- Lay the kite on the ground with the spars on top, and flying line removed.
- Flex a little more bow into the horizontal spar with one hand, and slip the toggle out of its loop with your other hand.
- Unwind the corner straps and loosen them off so the sail corners drop to the ground.
- Un-pick and loosen the tie where the spars cross.
- Lay the horizontal spar beside the vertical spar, on the sail.
- Pull the sail wing-tips together, then roll up the sail, starting with the spars.
wrap the bridle line around the kite a few times to prevent it
un-rolling. There it is in the photo, taking up no more space than a
Sled kite. A good way to make a Diamond kite if you ask me!
