Posted: Wed Feb 08, 2006 6:59 pm Post subject: TUTORIAL: Building an 8 ft Hexagon kite |
|
|
Hi Folks,
I hope that as this thread develops it can serve as a learning experience for anyone who follows along behind. I want to make it as comprehensive as possible and that if I make any mistakes (I’m sure there will be a few!) then others will be able to learn from them and avoid them on their kite. I know there will be lots of discussion on various aspects with forum members chipping in with comments, suggestions, support and humour (the humour is going to be a vital part of keeping my sanity at points along the way so keep it light hearted guys ‘n’ gals).
This is going to be a major project for my wife (Karen) and myself as we have never built a flat hexagonal kite before. They look deceptively easy but I am already finding out there are a lot of decisions to be made before you even start building. This will also be the first time we will be attempting the ‘back cut’ appliqué method although we have used other methods many times in the past.
The kite itself will have 336 individual pieces of fabric in the sail alone without counting the edge binding, ‘highlight’ strips, spar pockets, bridle loops and other sundry sewn parts. This is, by far, the biggest project in terms of ‘piece count’ we have attempted to date and we have built more than 70 kites or kite related items in the past 3-4 years, hence the trepidation we feel at the start of this task.
Background
This forum thread regarding hexagonal kites with kaleidoscope type graphics inspired this kite. I was so impressed with the idea I decided to have a go at building one of my own while waiting for the ‘Forum Build’ project to start. I started a pre-build thread here to discuss various questions I had regarding hexagonal kites in general, sparring issues, tails and the like so that I could be fully prepared (hopefully) when it came to the time to start building. If you are following along while building a similar kite I strongly urge you to read that thread too as a lot of important factors were discussed and they may not necessarily be repeated in this thread.
So let’s get the ball rolling and discuss the kite itself. _________________ Larry Green

Design Stage
I spent many, many, hours playing around in my graphic design software trying out various ideas in an attempt to come up with something I liked. Some I scrapped almost as soon as they were finished while others I toyed with for days changing a colour here or ‘tweaking’ a shape there. I would leave it for a few days and come back and decide I didn’t like it after all and change something again. I just could not find a design that jumped out at me and screamed ‘You have to build me!’ I searched the web for ideas, I used templates from stained glass sites, I searched clip-art CDs just looking for that one key piece of inspiration but nothing said ‘Build me!’
One day I just happened to be sitting at the computer, reading the forum and pondering just what I could change in the design of this kite that was now starting to get tedious. I don’t know if it was something I read, if it was something I saw or if it was my sub-conscious working away at the problem but I suddenly sat up and said that ‘That’s IT!’ It was a ‘Eureka’ moment or what the German’s call ‘Gestalt’ when the answer to a problem suddenly appears in your mind for no apparent reason even though you have been puzzling over it for a length of time. Once I had found ‘IT’ I was off and running! It only took a couple of hours to completely redraw the design and I knew that once I had the drawing finished that this was a ‘must build’ kite! I could tell that by shrinking the image down on the screen it was going to look the way I wanted it to in the sky and I had a surprise twist in the tail (groan……pun fully intended ) that would only reveal itself when the observer got close to the kite on the ground………BONUS!
This kite has all the things I look for in a great kite, good design, lots of colour and that little extra ‘something’ that makes it stand out as a unique piece of art! Hopefully the folks here on the forum will feel the same way about its looks and uniqueness as I do and I am also sure they will let me know if they detest it too!
OK, I have teased, hinted and generally worked a ‘wind up’ routine on you lot both in this thread and in the poll I ran asking whether you wanted to see the design before seeing the finished kite and it is time for the big unveiling! The results of the poll were to see the design first so here we go.
This first image is how I imagined the kite would look in the sky in my mind’s eye, the kaleidoscope effect is clearly evident but the nature of the things creating that effect cannot be seen. They just appear to be coloured ‘blobs’ without any true definition.
By the way, it took me longer to draw that picture than it did to create the design of the kite in the first place! I had a rough night due to my illness and couldn’t sleep. I read a book until 3:30 a.m. and then turned out the light and tossed and turned but could not ‘drop off’ to sleep. By 4 a.m. I was back up and fired up the computer to kill some time. I had that image completed by 11 a.m. and finally crawled into bed exhausted after almost 24 hours without sleep and slept like a log until the kids came home from school at 3:30 p.m.! Such is my life with ME/CFS!
Anyway, back to the kite!
I have mentioned that there is a twist in the tail with this kite. As you get closer to it the ‘blobs’ will become more defined and you will start to pick out the ‘hidden details’. What were ‘blobs’ will become recognisable shapes and you will hopefully get the ‘big picture’ and see what grabbed me so strongly when the idea first hit!
This kite is in fact a kite of kites!
A kaleidoscope of kites or if you prefer a……………
‘KALEID-O’-KITES’
So without further ado..........
I give you.........
drum roll Maestro please!
THE BIG PICTURE
So?
Do ya like it?
Huh? Huh?
Yes? No?
Well tell me then!
Am I on to a ‘winner’ or am I wasting my time?
Do I fire up the hot cutter or forget about the whole thing and take up knitting instead?  _________________ Larry Green

Actually parts of that 'scene' are from a kite I have yet to build! I just 'stole' a few parts of it to fill a space in that picture! The Canada goose and the trees are part of a Rok I designed three years ago and it has been waiting for the time when I can get all the colours together. I really must get around to trying your dying techniques for the three shades of brown I need to build it (I now have the shades of blue and green I needed thanks to my mystery benefactor ).
The river is 'adapted' from a Rok my wife designed and never built too! _________________ Larry Green

Cheers Grant, BTW did you ever dig out your black hexagonal kite and check the build details. I wouldn't mind knowing sizes of sail and spars and sail to spar attachment details if you could possibly do that for me. Please!  _________________ Larry Green

Just kidding but I don't think I would trust myself with a butane torch hot cutter. I'm dangerous enough with an electric soldering iron, ask Karen, she's felt the heat from it a few times when her fingers were too close to the edge of the template .

After completing the design stage I started on the next phase of construction………
Templates
I don’t have a lot of space to put large pieces of cloth on the wall to draw the design on the cloth and I no longer have access to an OHP to project the image onto the sail (or paper). Instead, I have to make Bristol board (poster board) templates for all the parts I need to build a kite. I import the design into my CAD program, break the image down into individual components and then add sewing allowances where required. While in the CAD program I fit the parts onto rectangles representing the boards so that I can get the maximum number of parts into the minimum amount of board (this saves me a lot of time and money later). I also fit the parts onto drawings of the available cloth shapes (remember I often have to build from scraps only) to make sure I can get the parts out of the cloth.
If I am building a multi-line kite with plain panels I try to align the parts with the ‘grain’ of the cloth so that the longest or most stressed edge is down the length of the fabric. If I am building an appliquéd kite then I don’t worry too much about the grain and try to get the most parts out of the material with the least amount of waste (the more cloth I can ‘save’ the more kites I can build!)
Once all those drawings are completed I can think about printing. I managed to pick up an old wide-carriage, dot matrix, printer for 20 bucks and it makes a great printer for kite templates. By using the tractor feed ‘computer’ paper I can print long runs which significantly reduces the amount of ‘taping up’ I have to do when working with large templates. I was also given some DOS software that will make a dot matrix printer think it is an engineering plotter! I have pre-made drawing ‘blocks’ representing sheets of paper and I take all the templates I made earlier and once again arrange them on the paper to get maximum coverage and minimum paper usage. I put the ‘blocks’ side by side where parts are too wide for a single width and draw ‘alignment lines’ across the joins so that I can line the parts up later. An example is shown below.
In the picture above you should be able to see the ‘alignment lines’ with identifying letters to show which parts fit together and also the ‘L’ shaped ‘scales’ I use to make sure that the printer is in fact printing to scale in both directions. Occasionally I hit a problem where one print run won’t exactly match with another print run due to the fact that the print head pins on the printer are at fixed distances. It can only ‘approximate’ curves and angled lines but I can usually ‘fudge’ the fit to get the parts to align satisfactorily.
If you are wondering why there are 4 templates for each part when I need 24 pieces of fabric for each part it is because the heat from the hot cutter causes the card to shrink and your parts start getting smaller and smaller! From experience I know I can get 6 pieces per template before the size starts to give problems so 6 pieces per template x 4 templates = 24 pieces of fabric . There are also 5 templates in that drawing I will use to help align the parts when I start the appliqué process. Can you see them?
The first time I used the printer I had to set up a ‘virtual printer’ in my CAD program as it would not talk directly to it. This ‘virtual printer’ is set with a custom paper size to suit my tractor feed paper and instead of telling it to print to paper I tell it to save the print job as a ‘plot file’ which can be read by my DOS software. Once all the prints are ready to go I fire up the DOS program, load the print file and go make a coffee while the printer chugs away and spits out the drawings. Once the drawings are printed (it is a slooooow process) I cut out all the shapes (leaving roughly 5mm all around), tape the big parts together and it is on to the Bristol board stage.
I take however many boards I need and use wide packaging tape to tape them together end to end and side to side to make a large enough surface to get the parts onto. Using a print out of the board layout I then start sticking the paper templates to the Bristol board. I use spray glue sprayed on the back of the paper templates not the board itself, if you spray the board it will be dry before you can get all the parts on! (DAMHIKTIJD OK )
At this point I find it easier to rough cut the parts out of the large board and trim them to size afterwards. Karen usually sits and cuts the curvy bits with scissors while I use my cutting board, rule and knife to cut the straight bits. The photo below shows a template with the curved bit already cut to the line ready for me to trim the straight edges to size. Some of the finished templates can be seen in the top right hand corner of the shot.
It might be worth mentioning the rule at this point as it has a nice feature that I find invaluable when it comes to using it to hot cut cloth if I am not using a template. The reverse side is covered in a thin layer of cork that not only grips the RSN and stops it moving but it also holds the rule just clear of the cloth which prevents the RSN welding itself to the rule!
Once all the templates are cut out it is time to clear the table, drag out the large mirror I use to cut on and get some heat into the hot cutter!

Hmmm........I've just had a second thought about this!
If you are in NJ and it's on its way to Steve in PA and he is going to pass it on to Cliff in PA who is going to give it to Gary (whichever Gary that is and wherever he is) and Gary is going to drive it all the way out to Dave in KS and then Dave is going to drive it all the way up here in Cananananada (BTW how do you stop spelling Cananananada) the damn thing is going to be out of gas 'cus it's a sure fire bet that they will all want to try it out for themselves by cutting out all the parts for their next kite before they pass it on so thanks for the offer but I think I'll pass
p.s. did that just win a prize for the longest sentence on a kitebuilder forum thread with absolutely no punctuation at all

I don't know if they will be much help since this is a much smaller kite But the kite measures 15 1/2 " on a side and 26 1/2" across. It is spared with 1/8" CF and has a long fuzzy tail (approximately 28' long connected as a loop.) It is bridles at the top left/right corners and middle. The spars are a little long and all go through the central bridle loop on the back. When they are in place, they force the kite into a slight concave shape(back concave) to give the kite some bow. The bridle lines also run over the spars at the top corners. I've only flown it a couple of times and don't remember exactly how it behaves but I do remember that it is stable enough that I can stake it out and not worry about it . Looking forward to progress shots of yours  |

Thanks for the info Grant and yes it does help. The fact they all go through a loop in the middle of the sail tells me the designer was concerned about the spars moving in flight and stopped that by use of the loop! As they are only 1/8" CF there was no real 'bulk' to speak of where the three spars cross so a hub was not required. In my case the three spars could be very bulky at that point so I will be using a hub of some sort and the hub will be attached to the sail to prevent the spars moving from the central point. The fact the spars are 'a little long' is significant too, see below.
Grant L wrote: | When they are in place, they force the kite into a slight concave shape(back concave) to give the kite some bow. The bridle lines also run over the spars at the top corners. |
Ahhh! We had quite a bit of discussion in the 'other' thread (link in the first post of this thread) with regard to whether these kites were truly 'flat' or whether they do in fact have a slight bow. The fact that your spars are 'long' means that they are 'inducing' the bow into the kite rather than it being bowed by means of a 'bow line' like a Rok or Genki. If you take something like a drinking straw and hold the ends against the palms of your hands and and slowly bring your hands together you will find that the compression forces you apply to the straw's structure will cause it to 'flex' and assume a curved shape. That is exactly what is happening on your kite and it is those compression forces that turn the flat sail into a bowed shape. The bridle lines going around the spars at the top corners mean the 'forces of flight' are applied directly to the frame rather than the sail (the spars going through the bridle loop in the centre are also directly attached to the flying line).
Grant L wrote: | I've only flown it a couple of times and don't remember exactly how it behaves but I do remember that it is stable enough that I can stake it out and not worry about it . |
That is interesting to note too Grant. The 'traditional' hexagonal 'flat' kites were known to be 'sky dancers' and would wander across the sky as they spilled air off one side of the kite and then the other as the angle of the kite to the wind changed. By introducing a bow to the sail you create stability (look at how stable a Rok is and that is just a 'heavily bowed' hexagon) and force the air to spill off the edges of the kite in a 'controlled' manner.
Thanks for taking the trouble of checking out the build details on your kite as it has really helped to clear some grey areas in my mind! I now know that I have to build a bow into this kite as I want it to be stable. It will be too large to risk it 'wandering' into other kites or going into an 'uncontrolled' spin and perhaps 'nailing' someone on the ground. As to how I achieve that bow is another question . I can either cut the spars long (like yours) and use the compression forces in the spars to induce the bow in the sail or I can drill the holes in the central hub at an angle of 1-2 degrees which will place the outer tips of the spars on a different 'plane' thereby achieving a similar effect (but not really a true 'bow'). Hmmm.......decisions, decisions . The easiest way would be to leave them long and try it. If it doesn't work I can still shorten them and then adapt the hub! _________________ Larry Green
