For some time we've been using simple 30 cm (12 inch) long kite winders for most of our flying. That size has proved just right for storing 150 meters (500 feet) of flying line.
The legal altitude limit in Europe is 150 meters, 80 in the U.K. (poor beggars). In the U.S. it's 500 feet, while in Australia it's 100 meters (300 feet) above the ground. We still use the 50 meter line for the 1-Skewer kites and occasionally for test-flying a new 2-Skewer kite.
Here's a refinement of our current 150 meter winder, in 2 versions. Can I be a bit pompous and call it the MBK150 Kite Winder... It will just make things easier later on if we have a number of these things lying around.
Firstly, for those in a real hurry, I will describe how to bang out a crudely finished winder that holds the same amount of line and has a similar ability to let out line continuously. To give it a name, let's call it the Quick Winder.
Secondly, I go on to describe extra steps to turn the quick winder into something much nicer to handle and use. It looks a darn sight better too! This one can be called the Nice Winder. There's a picture of it up there.
Now, I'm not an experienced wood-worker, so feel free to do the finishing work your own way if you can do a better job!
Rather than bore you with a bunch of long paragraphs, here's 3 lists that describe this kite string winder.
Referring to the plan, mark dots on the board, representing all the
corners of the winder. Then rule straight lines between them as in the photo.
Now draw in the outline of the winder. I've used a black marking pen just so it shows up better in the photo.
Cut along all the lines with the wood saw.
Using the file, round off the 4 edges that will come into contact with the flying line when it's wound on. Take plenty of wood off so the line doesn't have to go around any sharp bends.
That's it for the Quick version. If that's all you want to do, skip straight down to the section titled The Flying Line. Otherwise...
Round all the edges with the file, for handling comfort.
Go over all of the winder with the coarse sheet of sandpaper, to take out any file marks..
Go over it all again, with the medium sandpaper.
I used a piece of heavy chip-board, which had plastic veneer bonded to each side - so I skipped the dark wood stain! If you are using wood, use the wood stain on it now.
After the stain is dry, apply a coat of wood lacquer, and allow to dry completely. I used a polyurethane gloss product, which is supposed to be pretty hard-wearing.
Sand all over, lightly, with the light sandpaper.
Apply another coat of lacquer and allow to dry.
That's it, the finished article!
Just like we did with the 50 meter winder, the line is designed to be easily taken off the winder if necessary, and attached to something else. For example, another kite, as part of a 'kite train'.
Put a large double overhand loop into one end of 150 meters (500 feet) of flying line. See the photo on the left. 20 pound Nylon or Dacron is ideal for our 2-Skewer kites, while 50 pound line is safer for the Dowel kites.
Loop the line over one horn of the winder, as in the photo on the right, and wind on all the remaining line.
Put a double overhand loop into the free end of the line.
Have you ever wondered just how much line has been let out?
Here's a tip! Before winding 150 meters of new 50 pound braided Dacron onto its winder, I measured it out in 30 meter (very close to 100 feet) lengths on the back lawn.
I then tagged the line every 30 meters with a small square of colored electrical insulation tape, as shown in the photo. Placed diagonally, then folded over and pressed together to form a triangle.
Here's the color sequence, measured from the kite end...
Of course, the black tag is the first to go on, when making up the line onto the kite winder.
To make the lengths easier to remember, the colors get darker with every 30 meters. I suppose you could mark the lengths on the tags themselves if you really wanted to!
So, if the kite is directly overhead in a thermal, you have a good idea how close you are to the legal limit. Black tag marks the limit in Australia, empty winder elsewhere in the world, basically.
The photo shows the line attached to the keel of a kite, using a
Lark's Head knot. The knot is left loose to illustrate how it's done.
Can you guess which kite it is?
That's a handkerchief-sized rag being dragged along a pathway, as I
wind on line as fast as I can. Just to give you an idea of the winding
speed. It's handy to be able to get line in quickly sometimes. Example -
the kite's down, some distance away, and it's starting to rain!
The second video... Rapidly moving further away on the end of this line was the 2-Skewer Barn Door kite, up at around 50 meters (160 feet) in a stiff breeze. Watch that line fly off, loop by loop!

This was an experiment with mounting a camera directly onto the kite. With winds gusting to over 30kph up high, the Fresh Wind Barn Door kite was selected...
In a word, it was tricky. I mounted the camera as close as possible to the center of gravity of the kite, but it still ended up quite a few cm closer to the trailing edge than I would have liked. It was only practical to mount he camera - on its bendy tripod (!) - near the diagonal spars crossing point. Electrical tape secured 2 short tripod legs to the diagonal spars, holding the camera upright with the kite sitting on its trailing edge.
It was a struggle to get enough lift to gain much height, and the kite swung dangerously from side to side. Might try the drogues next time! I did my best to urge the kite higher in mid-swing.
Eventually, for a few seconds, the kite got to around 100 feet on almost 200 feet of 200 pound Dacron.
A video clip will of course be forthcoming on Facebook. And only seasoned kite fliers will bother watching it all the whole way through, possibly wrestling with sea-sickness all the while. Hence the title of this post. Still, it was an interesting, if slightly nerve-wracking, outing! At shoulder level, the breeze measured around 9kph gusting to 18.5kph. Some low cloud over the hills was absolutely tearing along, perhaps up around 40kph.

"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've just bought your super e-book and spent most of last night pouring through all the great stuff in it!
Very detailed and USEFUL information - thanks for such a great book."
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!"
"omg i made a kite from this site and i fly it ....... booom i didnt expect this bc in the other sites instuction are trash
to try these books
