Snap Shackle problem

Postby downunder » Fri Nov 23, 2018 4:23 am

Hi guys,

for foiling I'm using this shackle, but hey, pulled too much and BANG! Luckily happened on the beach, no harm done, except the spring is gone...

How do I solve this problem from happening again?

Sorry but this look like troll bait :)

If not and its real question - dont use this shackle as it certainly doesnt release under load as accidentaly release as you find out. So use either wichard shackle or made small ball pin release - there are plenty info here.

Thanks for reply,

many are using it, wichard one is $90-100 here, multiply this with a few bars. wichard one can release too.

It wasn't accidentally released but with too much force, hence pin ejected, and spring lost.

reminds me of old times!

And still people didn't learn from the past...

The shackle you are using is DANGEROUS !
The loop or whatever you use will get stuck on your model.

The only safe shackle is this one: http://marine.wichard.com/rubrique-Swiv ... 00-ME.html

Thanks Toby,

as said, we know the risks. I'm looking for the solution of minimizing it. Don't be fooled by the above, it CAN open. The condom CAN break ;) The elimination of the risk is not to have sex at all :) :) Minimizing it is something else.

then ball and pin - cost max 5 $. Look at this thread
https://www.kiteforum.com/viewtopic.php ... 0&start=60

I use it on all bars - no accident release and easy to release by full body weigh - tested to 400 kg /strength - not release/

but devil is the detail - use , swag eye pin for 2 mm or 2.5 mm rope and use a SS ring made from 4 mm wire
Best balls are delrin valve balls as they are rigid and smooth I use 30 mm - Drill accordingly to swag eye head - as big as possible but small enough to pin head cannot goes through.
You can also use standart table footballs 36mm balls. These also comes in red but delrin is best material overal. Anyway both works.

To answer your question : Back in the day when we (Briefly !!) used those, I used to braze/solder the split ring to be a ‘solid’ ring that still swivels in the pin.

As others have said..this type of shackle should NOT be used as a safety release.
Have you actually tried to release under even moderate load? I think you will be shocked at how much force is required. Also they can and do jam up with sand.

Let me add, that if you use a metal ring with the right diameter, the shackle shown by me will always release.

If you use e.g. a chicken loop it can get stuck, specially on the o.p. shown shackle.

I know a lot about this, because back then I was a partner in kiteproshop.com and X-Shooter...we developed two bars based on snap shackle and it was the first spinnable bar with safety leash. We were the first using two depower lines...

We tested a lot to make it really safe, therefore my knowledge about this.

Hi downunder, just make a knot from the rope to your harness; when you are finished your session, if it's too tight just cut it with a pair of scissors. It's not any less safe than the shackle you are using! And it's cheaper!!

Hi sarc,

are you sarcastic by nature or just by your nick? ;)

I do not question your expertise on the risk, ok?

And I don't judge. Toby not riding smaller kites in 30-40kn? Who am I to judge? That is HIS risk assessment (we all know that as a fact so...)

This shackle is acceptable for the purpose. The rope around the pants belt is also acceptable for the purpose sarc. Riding suicide too. Riding unhooked for 20km is also acceptable. And the list goes on. Not acceptable for you? Than don't do it. Don't judge others who are doing it tho. Or you'll get a society of sheep and no diversity which makes us as humans.

Is that too much to ask?

Thank you.

PS
Can't resist, this avatar on the right is from active vulcano 3800m above the sea level. No ropes, no shackle, no safety. People dying on the climb. Get over it.
