 Posted: Sat Dec 18, 2004 4:05 am Post subject: 5m Junkie Traction kite |
 |
|
G'day all 
So, going from small to big, I've finally aquired everything I need to build me a big traction kite. A kite for snowboarding and mountain boarding. I've settled on a 5m Junkie kite to start with.
I'm useing Foilmaker to generate the plans and templates. It's a great program.
http://foilmaker.co.uk/
Here is the .kte file for the kite I'm building:
Progcraft's Junkie
The is the VRML for it. A virtual kite. The is NOT the colors I'm useing, but it this kite and bridle. The Virtual Kite is pretty cool once you get used to the controls.
VRML file
For you windows users, you can use Cosmo player to view the file and is available from the downloads section of Foilmaker site. Once Cosmo is installed, the file is viewable in Internet Explorer. You other O.S. users already know what your doing
In the begining:
42 sheets of posterboard for templates.
297 printed sheets of templates. (It's a big stack 'o paper)
One roll of fabric
Phase One:
Glueing the printed sheets to the posterboard and rough cutting them.
Used so far:
4 sheets posterboard
42 printed sheets (255 left to go)
Those are the first 9 profiles in rough cut. I ran out of knife blades so will continue tommorrow This is going to be a long haul, but I have all the materials I need. I have the equipement to use. I have the knowledge and plans. And I think I have enough skill to pull it off now. Traction kiteing IS the reason I started building kites to begin with. Now I can't wait to get a real engine running
Cheers,
P.

I'd like to build myself something around the 9m range out of icarex or equivelent for those light wind days I still want to buggy. Moving 230lbs fast takes something big. (My gf just gave me my present early since we have been having decent weather. I ripped my 6m radsail bridles off at the seams in 25mph winds.) So she bought me a peter lynn c-quad 6.3m to try out. I built my own buggy but have experience from the past on my father's 4 wheel and 3 weel buggies. good times. Can't wait to see more pics of your progress on this project.

That's quite a big project. The Junkies always intimidated me with those shaped skins and the need to print a gazillion Foilmaker templates. I fly an Eliminator, but it lacks the smooth power transitions of a curved canopy.
When you're through, you''l have a masterpiece!

G'day.
Ok, all the templates for the profiles have been final cut. I used a hole punch to make holes where the bridle points and vent openings are. That way I can easily mark the fabric.
89 printed sheets and 10 pieces of posterboard total. 208 printed sheets left to go
  The stack thins
Cheers

That's great! Another junkie going international 
As one of the Wingine (and Junkie) designers, I'd like to know how you're moving along.

Well that's pretty cool. Hi emiel! Just shows Kitebuilder forums riseing to the occasion again by bringing builder and designer together
I'm useing a 1.0 oz fabric, so I made a couple changes from the original S50 file. I removed the D-Ribs. that's a lot of 1 oz fabric. I did also change the bridle to every 2 ribs, but kept the half-cross style.
I've have the templates the first 4 cells, top and bottom final cut, and cells 5 - 7 rough cut. I'm hopeing to get the templates for at least 12 - 15 cells, top and bottom skins today. I think I've almost worn out this pair of scissors. Have to break in a new pair soon
Just keep visiting this thread, and you'll see how I move along with it
Nice to have you aboard emiel!
Cheers,
Progcraft.

Ok, first question, if you don't mind  , Do I have to add a re-inforcement on the profiles for the bridles? If so, should I use a dacron line (I only have 250lb available), or will strips of 4 oz dacron work? And how long should they be? I'm talking about the 'V' shape on the profile itself, where the bridle attach is at the bottom of the V. (know what I mean?)
Thanks in advance
Cheers,
P.

I don't use the bridle reinforcement on the profiles any more.... I just sew them on the lower skin back-and-forth.

That's awesome
On this 'Makeing a firecrest site, he adds a line for reinfocement. That's the only 'how-to' I've seen for this type of kite.
Nice to know they're not all together necessary here
Well, back to glueing, placeing, cutting, glueing, placeing, cutting, cutting, cutting, cutting, ......

Yeah, it is. And like you said, there's a lot of printing. But, it's going suprisingly quickly. And anyways, I think the end result will be worth it. The NPW's are quite fun, but I don't feel very comfortable on the mountain or snowboard. They work great in the buggy though.
This kite should be be suited to stand-up kind of riding. I want that easy up-wind capability.

Will I have any trouble, or odd flight, if I mix in a bunch of .75oz fabric?
I'm still undecided on what color the bottom skin will be. I could go with all one color for the kite. Utilitarian, and not too pretty.
Or, I could use some color on the bottom and make a number of the panels out of yellow, teal, and pink. Will mixing the .75 oz with 1.1 oz be ok? Should I concern myself with symmetry if I do mix them?
Thanks
P.

G'day
Ok, all profiles have been hot cut. And, all top skins have also been hot-cut. And, the bottom skins for cells 10 &11 have also been hot cut. 
Depending on what I do for the bottom skin, I may take up to 3 days to completely cut it out. I think I'm just going to throw a few colored panels in. Nothing fancy. Just something to break up the main color.
Total material used:
28 sheets of posterboard for all templates. Adn 9.8 meters of 140 cm wide fabric.
Cheers,
P.

I try NOT to mix fabrics as they MAY stretch diffrently.... It depends on how big the pannels are compared to eachother, and the size of the kite.
It also depends on how the fabrics were woven and what coatings were applied...
The problem with a traction kite is you are flying it in the power zone most of the time in a effort to pull you along... This puts a lot more force on the kite's parts than a SLK flying at the top of the wind window...
Personaly I would not mix fabrics from diffrent manufactures and diffrent weights (except for reinforcemntes) but you may get diffrent results.
There are also kite builders who will allign the warp and weft of the fabrics they use to minimize diffrences from one color to the next from the same series of fabric.

Ok, thanks Squid. You've about convinced me.
I'm going to use a single yellow piece for the middle, lower skin, and I'll use two pink or teal panels beside it. 3 colorwd panels just to break up the monotony of the rest of the kite.
Cheers,
P.

Whew!!
All the fabric is now cut. 98 pieces (well, 99 actually cause I cut two upper 17's when I only need one)
Tommorrow night I'll make the bridle tabs and cut the edging.
Ok so, how the heck do I sew this thing together?? 
Cheers,
P.

I doubt if mixing fabric would be a problem, but it's worth being extra careful on such a complex kite.
You must be a patient fellow to just get this far...I'm impressed already!
This will be fun to watch! |

Hi.
I have a question about edge binding the the vent opening part of the ribs.
The 7mm seam allowance is on the profile. The long line is the edge of the profile (sew line) Between the dots is the open vent. (the short line 1/2" from the edge, between the dots is just an extra line)
How do I edge bind this part? Or otherwise reinforce it?
I was thinking of just folding the fabric over the required amount and add the binding over it. Same as the leading edge of the top/bottom skins. But, I'm worried that doing so won't leave much 'meat' when I sew the skins to the profile.
Can anyone advise me on this part please?
Thanks in advance
Cheers,
Progcraft.
