Thanks guys!

Kitexpert I totally agree that no trimming is the goal, no unnecessary deforming of the kite.

Stef – You are certainly a very talented individual, from planning, manufacturing, documenting as well as presenting the finished product via video which are excellent.
Looking at step 14 “Assembly Bridle Lines” using Liros DC lines, I will look into making bridle lines the very same way as splicing and sewing through a single line looks easier than sewing a looped bridle line with a dyneema core.

Thanks mgs! on a previous generation I used sheathed lines and it was definitely more difficult. With both types of line I made custom presser foots (3D printed) to hold the line perfectly - but the Liros DC lines are very easy to work/splice with. -stef

What do you mean by "presser foots", just curious about your splicing setup. Awesome work!

Hi volume311.

The presser foot is the part on the sewing machine that presses the material against the feed dogs, pulling the material along perfectly timed with the up and down of the needle. I design and 3d print my own presser feet because the foot that came with the machine is not able to hold the very thin diameter lines perfectly in place.

As you can see in the bottom picture, the guide I made for when I used to use the sheathed line would squeeze the line together and hold it steady. I broke a lot of needles!!!!!

I should also add that I have a cheap home sewing machine. I imagine a more professional machine would be more predictable and easier. -stef

When it finally arrives I'll be making new bridles for my fone diablo. They are threaded into themselves and sewn. A technique I really like for simplicity but I no longer have a sewing machine or that presser foot of yours.....looks like it would make my task a hell of a lot easier. But I'll be sticking with a brommel lock splice, will be strong enough and your right, the dc line is super easy to work with.

Very smart solution! From watching the "how to make a kite" video in the dumpster fire of a thread on the main page, the production bridals are stitched by hand feeding the machine, but like you said, proper machines and the kite makers run thousands of bridals.

Hi all, the next generation is well underway :) Same 25 cells but aspect 6 instead of 6.75, and new profile as well as a lot of subtle changes as I try to perfect my design.

I also made some custom adjustment rings (so I can dial in my kite and only have to undo knots on the mixer one time at the end!!) and if any of you would like to 3D print them for yourselves here is the stl . (obviously you can scale up the stl if you want even more coarse adjustment.):
