As Toby is about to say : No need to be disrespectful.

@ jaystore

About how durable is the plastic in your slider, compared to Delrin ?

We have a proposal, we will send to LetsFlyaKite and Bille the new low friction ring for free and they will report on the forum their feedback.
Please send address in pm :thumb:

Sending them out to try I understand. Sending one to Billy I understand.
Why would you go out of your way to feed a troll? That I don’t understand, it just encourages him.

That's Awesome jaystore ; but could i find you a better suited candidate
for your product , (someone with better riding ability) than me, that
owns one of your sliding harnesses ?
I basically spend WAY more time flying PG and HG, than i do kiting ; and
most my kiting is on land, (bin that way for 3 years now).

I'll back OFF that LFAK now ; and thanks for the offer, (but no) !!!

YES i use your Dynabar-V7 with my land buggy ; makes for a better
more comfortable ride for me. And Yes i'll purchase one of your low
friction rings , (when Ya get it sorted out).

Please do NOT give up on this project of yours ; it's worth the time invested. :thumb:

Just make sure you enclose "signed for" instructions and a tube of Loctite 243 when you send to LetsFlyaKite. :lol:

Are you sure you want to ship to Hawai ? (LOOOOL)
To this 7 figures worth (LOL) that brags about ripping off a newbie for a used kite?

I know for a fact that I am already better at kiting than you, and probably living way better than you ever will. I own a house, own a boat, and already close to being worth 7 figures. What the f*** do you do for a living? Sit on your ass all day collecting welfare? Collecting beer cans out of dumpsters so you can get 50 cents at the recycling center?

Hardwire your chicken loop to the buggy Bille. Its way more fun. You can ride stupid powered without breaking your ribs, you never get plucked out of the buggy and you now have another 50kg of weight to lift of the ground.

Turtling the buggy does hurt however!

Man, I was reading this thread and was surprised at all the emotions. Chill out people, if some dude post stupid shit, just don't reply.

Jaystore,

If you want me to print some things out and test them I will for a new dynabar :) I've been printing for 5 yrs. My opinion is any typical material will wear out quickly regardless of the infill %, but I'm only about 80% certain on that. If you have evidence of it working on a ring I'd like to see it. I'd also be careful of liability. Any printer knows layer adhesion, part orientation, etc, can be an issue and certain batches of filament can cause problems. 3d printing for functionality needs to be done with care. Those rings I think are going to wear out fast in anything other than nylon, which I don't have experience with. Nylon needs too hot of extrusion temperatures for me. The pulleys may last, but I still bet they wear out. The quick release pull would be my greatest worry about getting the print correct. I've printed stuff out for a 4 ton press stamping on stainless steel and it has held up for months, but this is not friction, damn fucking strong tho I tell you! The friction pieces I've printed out have not held up.

Regarding the 3d printed piece for the rope...I've tried this and it does help for a while but the plastic wore out. Your parts are a little thicker than mine, but I still see the same outcome. I smoothed out the dynabar holes nicely with a dremel tool and I don't have any issue with dyneema strands breaking or getting cut at all. My rope always needed replacement before this was a problem anyway. I suggest adding another rope with extra slack in case your main line breaks...

Here is a fin I printed that has lasted a year. I can't remember but it was about 50% infill. 100% is not feasibly for a few reasons...the most you want to go is I'd say 95%. I'm also in the middle of a big foil project and we are starting by doing a functional mold for a stabilizer to test on my foil.

All in all, I encourage the process you are on, but make sure you have some field tests on what materials work and if they are wearing out slowly or holding up rock solid. Good luck, if you need any field testing dm me.

We print only SLS technology and the polyammide layer is 0,1mm with a result of very compact and strong parts.
This plastic is also slightly elastic, slides better than metal and the dyneema lasts more time.
Please check our new 3D shop on SHAPEWAYS.COM and verify yourself the material they use.
