One of the most popular sections of the GWTW Forum has long been the Swap Meet.  A great place to sell old, seldom flown kites or to get great deals on used (gently flown) kites.  Only registered users can see the Swap Meet section, let alone wheel and deal.  1000's (literally) of kites have changed hands thanks to the Swap Meet.
There are several more benefits to being a registered user, but you'll have to join our little community to find out all the "secrets".

I've also read that a 'sharp' point needle can cause problems with some materials such as the rip-stop poly & nylon sail material. The Blue Tip #11 needles are ball point so the concerns of a 'sharp' needle sheering the fabric aren't there with those, IMO. I use them for the entire sail as well as the leading edge & trailing edge strips. I'll ONLY be using the Red or Purple needles for the kite nose, sewing the trailing edge stand-off reinforcements material, center 'T' reinforcement & upper rub patches ...all with the black DaBond V46 thread I have. I recently found a vendor that sells V30 DaBond in black, green, navy, red ...and white ...and I plan on purchasing a spool of black from them at some future time.

As for the red & purple #14 needles ...their purple tip needles are also ball point with only the reds being a 'sharp' point needle!

The unique design of the Janome's has a slightly longer than normal scarf to cure skipped stitches and puckering in any problem fabrics. It also seems to help keep the needles from getting gummed up from the use of seam tape!

Hi guys.  Forgive me for reviving such a relic of a thread.  I kind of had to.  I can't figure out how to get my file size small enough to post pics, so I found this thread containing essentially the same pic.

I have a Red Shadow from back in 2008 and I have had it in storage for several years.  When I broke it out, I noticed this fourth slack leg on the bridle.  If you look at the pic posted by mcocola, you can see the slack leg.  Incidentally, I have the same question as him.  Is it necessary, and what is it for?

On a related note, I was not able to modify my bridle to compensate for the over steering problem.  Any pointers would be helpful.  Keep in mind that I am not absolutely certain what each leg is called, and exactly where each leg ends with this turbo set up.

LAMO... don't count on it.  But if that ever happens, dibs noted/acknowledged.   Wink

@ Frazer... from first impressions, someone would need to pry it from my dead hands.
Yeah, right ... something new an shiny will displace it in your affections ... I've seen all this before ... and I'm patient.

there was some interesting talk on kitebuilder about needles.
One of the things that came out from it to me was that sharp sharp needles are not necessarily the best to use on ripstop.  the needles can be so sharp that they cut the threads.   A ball point or jean needle is better for ripstop as it pushes the threads away from each other and causes less damage.
I am not certain how that would work for you with the tape you have in your seams though!

Old skool flyer coming back to the scene... looking for advice!  I got a few larger soft foils and 9' deltas and boxes of line laundry (some I have yet to open) and ready to paint the sky.  Advice on how to approach this?  I am certain space is limited and I want to be a "Good Neighbor".  Any advice?  With the larger soft kites (3M/4M/7M foils) I have sand anchors and line that exceeds what should be necessary, any other safety recommendations?

Appreciate any feedback, and looking forward to meeting folks there!

@ Otherone... Yup!  I'll be there both days, but leaving around 5ish on Sat to attend my kids concert at Segerstrom Hall.

I thought I'd share an excellent product discovery that was recommended to me by the experienced Sewing Machine dealer that I bought my Janome Magnolia machine from. 

They are designed to cure skipped stitches and puckering in any problem fabric especially synthetics.

Here's an excellent review of Janome's Blue tip #11 needles, Red Tip & Purple Tip #14 needles: https://janomelife.wordpress.com/2013/05/10/product-review-sewing-machine-needles/

I just ordered more of these excellent needles for sewing kite sails with panels that are held together with seam tape first! *The Blue Tip needles also don't seem to gum up as easily as other brads if you are using double-sided seam tape to hold your seams together before sewing! I haven't used the Red or Purple Tip needles yet (I just ordered some for heavier V46 DaBond sailmakers thread) but expect they will work well too.

Well I just pulled the trigger on a small 1.2 snapshot.  The price was right and it will give me a reference for buying bigger foils.  It will also serve as an extra kite for all the other yutes I have under my wing.  Now I just need to figure out if a snapshot at a particular size has a comparable pull to other common foils of the same size.

Continued: picking up with #2 of design aspects to consider when working with blank canvas. 

1. Symmetry (covered in last post)

2. Take into account the skill of the builder (likely looking at yourself).
- the community has proven that almost any design can be turned into a kite...
examples include many, but Revolution Master's kites come to mind as well as the Parafoil rebuilds by Kieron Jansch (incredibly entertaining time lapse documentation on his website)

- limitations may include the builder's comfort level sewing curves vs straight lines.  This should be of minimal concern, as the skill is essentially the same and obtainable after building one or two kites.  More important is the quality of a sewing machine and it's ability to feed material evenly.  Where curves become difficult is in the layout and assembly of sails with the addition of a billow (3d shaping of the sail).  This discussion will not be covering the physics or aeronautics of kite design, as it is merely addressing the artistic/graphical side of the process.





- how many panels are in the layout (can number of seams, whether seams end in the middle of the sail vs the edge where the ends are covered by edge binding and the leading edge tunnel.  Also will increase the time: to make templates, to cut, layout and prep a sail and to sew it.

here is a SportKiteDesign Seven which has at my count 17 panels per side (or 34 total).  Thats a lot of templates to build, panels to cut and seams to sew!


and then a fine example of the simplified Le Quartz plan on Tom's Kite Building website.


- do you know how to appliqué?  a sail can be cut from one piece of material and then by use of appliqué technique designs can be stitched with layers of fabric that are cut away around the seams to reveal a pattern

Here is an example of appliqué... the letters of this NPR kite were sewn in with the different colors layered around them, and then I cut the fabric away to review the design.  This is a simple example of appliqué, which can also be done in an incredibly complicated way I've yet to tackle myself.


- is painting required to reproduce what you've conceptualized? if so, the skill and know how to paint is required and not discussed beyond this point of the thread
