On this site, there's more kite-making info than you can poke a stick at :-) Want to know the most convenient way of using it all?
The Big MBK E-book Bundle is a collection of downloads - printable PDF files which provide step-by-step instructions for many kites large and small...
Every kite in every MBK series.
1-point, 2-point, 3-point ...
A 2-point bridle, for example, means that there are short lines coming from 2 separate points on the kite's frame, which then come together near the end of the flying line.
An anchor is an object such as a small sand-bag, that is used to tie down a kite. Hence the owner can walk away and observe the kite flying without actually holding on. Very large kites are often anchored to heavy 4WD vehicles!
This is the curvature in a spar, like a drawn bow in archery. Most commonly, there is bow in a kite's horizontal spar which provides greater directional stability. With enough bow, kites need less tail or even no tail at all, to fly stable.
A bow-line is a commonly used method of maintaining the bow in a spar. A line is tied from one end to the other. I like to use a toggle so a 2-piece bow-line can be undone, leaving the kite flat for transport.

This is the amount of tension it takes to snap a piece of line. The strain is commonly measured in kilograms or pounds. I like to take a set of spring scales with me to the flying field, so I can check how hard my kite is pulling! A knot tied into a piece of line will decrease it's breaking strain.
This is a general term for all the short lines that are attached to the frame of the kite, some or all of which come together at one point where the flying line is attached. For my MBK designs, there is also a short connecting line coming from the bridle, to which is attached the flying line.
A section of line going from the kite's frame towards the flying line is called a leg - 2 such legs can often be part of 1 piece of line which has both ends attached to the kite. Hence this term is a little more precise than bridle line!
One of the pieces of line in a kite's bridle. Confusingly, this can refer to either a bridle leg or a bridle loop! Bridle line is usually the same strength, or a little heavier, than the flying line of a kite.
A piece of line, both ends of which are attached to a kite's frame. A horizontal bridle loop with a sliding knot in the middle allows side-to-side tweaking to get a kite to fly straight. Similarly, a vertical bridle loop allows fore-and-aft adjustment to cope with low or high wind speed. Or to get the kite to fly at all :-)
To take aerial photos with the camera suspended from the flying line, the camera is inserted into a light-weight cradle. Mine is constructed from bamboo skewers and paddle-pop sticks. It's done the job for many years now. There it is in the photo.
A long cylindrical piece of hard material. My Dowel Series of kites use Tasmanian Oak hard-wood dowel for all the spars and spreaders.
The bending, stretching or compression forces exerted on various parts of a kite due to the fact it is in flight. Spars bend away from the kite flyer, sails eventually stretch like an old pair of jeans and spreaders of delta kites are under compression during flight.
This is the piece of line going from the ground to the bridle of the kite. See if you can spot the kite in the photo! Braided Dacron is the line material of choice for most single-line kite fanatics. More expensive materials are also used, which are stronger per unit of weight.
The frame of a kite is made from several sticks called spars. See the 3 sticks of the kite's frame showing through the pale orange plastic sail, in the photo. It is normal for some distortion of the frame to occur in flight. This becomes most apparent when the kite is close to it's upper wind-speed limit.
An end fray
The cut end of a piece of line will fray over time, as the fibers unravel. Some kite flyers, like myself, like to put a simple knot into the line right near the end, to prevent any fray from progressing further. Others like to melt the end of the line with a flame, which is a somewhat neater approach. 'Fray' can also refer to damage that occurs mid-way along a line due to abrasion. In that case, broken fibers can have a fluffy appearance and indicate that the breaking strain of the line is not what it used to be!
This is the stick that holds out the 'wings' of a typical sparred kite, extending from one side to the other as you look at the kite in flight. Some kites have more than 1 horizontal spar. Modern spars can be rods or tubes of artificial material.
Keels are less common nowadays and are most commonly seen on delta kites. A keel is most often a flat triangular sheet that is attached between the end of the flying line and the vertical spar of a kite.
This refers to line of a type that is useful for many applications in kite flying. For example, the flying line, the bridle lines, ties and other uses associated with attaching stabilizing devices to the tail end of a kite. The line in the photo is 50 pound braided Dacron.
That part of a kite which, when all is well, points directly into the wind when the kite is in flight! The nose is at the top, initially, when the kite is first launched.
A knot which can remain done-up while being shifted back and forth along a piece of line. I prefer the Prusik, since this knot can be unlocked for sliding and locked again to hold the desired position. It's a complex knot, but it doesn't have to be undone! With plenty of unlocking and locking, the short end can eventually pull through, so I usually use a terminator with this knot. Unlike in the photo, which is just illustrating a locked Prusik.
A stick, rod or tube that forms part of the frame of a kite, to which the sail is attached. Bamboo is a favored traditional spar material while modern spars can made from fiberglass or carbon fiber. GRP (Glass Reinforced Plastic) is a term often seen, which is the same as carbon fiber. I like to be different, with most of my larger MBK designs using hardwood dowel and carefully designed bridles to ensure the wood doesn't snap in flight!
This is the cross-stick that keeps a delta kite (for example) spread relatively flat during flight. In the photo you can see the ends of the spreader poking out to left and right.
A length of line that suspends an object from the flying line of a large kite. Objects such as non-flying inflatables, a camera cradle or a flag. See the suspension line near the top of the photo - passing through pulleys and holding a rather fancy KAP rig for aerial photography!
A length of light material which is attached to the tail-end of a kite and serves to keep the kite pointing into the wind. Sometimes many tails are used. Tails can be useful hanging off the wing tips of a kite, to help dampen it's motion in the air. Tails are also useful purely for looks!
The knot that will be back. Just kidding - I use a terminating knot near the end of a piece of line to prevent another knot from pulling through when under strain and/or motion. In the photo, the small Loop knot terminator to the right will prevent the simple Slip knot from pulling through when tightened. A Prusik knot will never pull through immediately after being tied, but it might eventually, after a lot of use. Hence a terminating knot is handy. Here's another example - a Simple knot terminating the end of a line will prevent a long fray from developing.
A short piece of line that attaches one part of a kite to another. For example, a shoe-lace that is used to tie 1 spar to another at the crossing point. Or some light line which attaches corners of a sail to a solid part of the kite, as in the Dowel Dopero or Roller designs.
With MBK kites, a short piece of dowel that is inserted through a loop to secure a 2-piece bow-line in the middle. The 2 lines are drawn together, bending a spar, before the toggle is inserted to hold some bow in the spar.
Or tow point. Or more technically, the fulcrum of a kite. This is the point or points around which the kite is free to rotate in pitch. That is, in a nose-up or nose-down manner. For most single-line kites (but not sleds!), this point is where the flying line diverges into several bridle legs which attach to the kite. As in the illustration. The position of the towing point relative to the kite makes a lot of difference to how the kite flies - or if it flies at all! Some kites have a single attachment point to the kite - in this case, that point is also the towing point.
A number of kites all flying on the same flying line. A simple example is a train of diamond kites where the flying line attaches to each kite at it's towing point on the vertical spar. For the simplest of diamonds, this where the sticks cross.
The stick or tube that goes from the nose-end to the tail-end of a kite and is sometimes referred to as the 'spine'. Some designs, like the Dopero and the original Genki, have more than 1 vertical spar.
That's it for this glossary of kite parts. I hope it has proved to be of some use to you!
