this is a bit off topic from Dynabar, but anyways;

Tomatkins etc. would this carabiner work just by itself, ...


I started This Topic, and i would be the (("LAST")) person to bash a guy for
making his own stuff !!! I made my own board to learn on and Still use it in
light wind. I started the mods my 08--13M Ozone Edge even though i got
a 2010 same size & brand. I totally changed the QR on my bar to get a longer
reach on my sheeting for my long arms.

I posted this on the the topic at the bottom of the index by --windyway--

My Dynabar V-7, has a FULL 12 inches of travel, (305mm).

It has a Nice Soft frame that my belly Likes !

It has a Big Hook to attach my chicken loop to.

It's got a Pulley to make the travel Really SMOO00oooth !!

And 321 kiteboarding will sell Ya the V-7 for $87.99 ---

Hardly worth the effort to make your own ; "Especially", if Ya Screw-Up
Ya Could Die !!

Seriously -- i can't really see burning the time and money to build a device like the
V-7 when a new one is so cheap ?? !
Add it up for all the stuff Ya need and forget about the time in labor,cause I Like making
stuff Also .

And For the record :
i Still owe (321) for my V-7 till i actually win the bet ; but after using
their device , i have No problems with paying them the Full Retail price for it .
Its Quite well made, i like the 13 inch wide padded spreader Best, doesn't hurt my ribs any
because it's size spreads out the load so well !!

Look at Wichard they have great rings, shackles etc.

As well as my Dynabar I also have a harness with a spreader bar that has the hook cut off, a dyneema line attached at each end and this shackle on the rope but snapped on the chicken loop.

http://www.wichard.com/rubrique-Quick_r ... 00-ME.html

They have greaty breaking strain too.

mike



Those QR devices "DO NOT WORK WELL" when Sand is added to the mechanism !!

How do i Know ? the top one is the one i used Before i got the V-7.
First thing i would do is blow out the sand Before hooking in ; then wash
it when i get in the water. And your gonna Shit when Ya see the price ;
you can almost get the Entire V-7 for the money.

Actually you CAN have a V-7 and a 6-pk of beer, if Ya purchase this QR from West Marine :

Billie,

Don't get me wrong, I love my dynabar and have been recommending them to people for ages.

My wichard has given me over 10 yrs of service and still works like new. Plus the chicken loop QR is the main quick release. Plus in the UK 10 yrs ago it cost me £20.

I just got the V-7 and can't waite to try it out.

I set up the larger roller with the rope. The roller is not rolling. Should it be? Does it matter? Is it possible to screw it down too tight? I'm not sure how tight it should be I just don't want it coming loose mid launch. :nono:

If that didn't make sense, maybe this will clear it up for you.

I would like to see a spreader bar with a QR instead of buying a QR with every control bar. It seems to me this is an area where cost of kite boarding could be cut substantially.. With new bar prices are now > $400 it can add up quickly. Having a QR in the spreader bar also frees kite boarder to change bars without re-familiarizing themselves with a new QR.

It is not really different in function from using a Wichard QR shackle, except I am using a hook designed for kite boarding (I would not argue that is a significant difference). I bought a Slingshot "SureFire" spreader bar, detached the hook and added a shackle ring. The Surefire spreader bar retails for about the same cost as a Wichard QR shackle http://tinyurl.com/6ujv55q although I did buy mine new at a substantial discount. Also, I still need to make my own bar set up with a simple metal ring attached to the depower line.

Constructive criticism welcome

Notes:
1. I just put this together as an example. it is NOT a final working version
2. I want to put two thin nuts together on the end to lock it so it cant unscrew.
3. I would like to add a plastic washer next to the shackle ring. It is probably not necessary, but, I would like to avoid metal to metal wear if possible.
4. It would also be nice to add something like this low friction ring materiel to the shackle ring so the rope slides easily. http://www.antal.it/Inglese/Inglese.htm Go to "Accessories", then go to "Friction rings"

Pros
1. One QR for all bars (assuming you could buy bars without QRs from different manufactures)
2. Spinning hook to untwist front lines
3. Sliding hook.
4. More affordable due to less expensive bars. It is not about spending less money as much as it is about spending the same amount but being able to buy more gear.
5. Less complex bar setups


Cons
1. Not good for unhooked riding. A Surefire spreader bar with the hook attached or similar with a larger hook would work well and still provide spreader bar QR functionality.
2. Does not have 360 degree access to the QR mechanism. I am sure designers could overcome this hurdle.
3. You would need to make your own bar setup with no QR unless manufactures offered this option. this is actually a "Pro" for me because I like making gear.
4. Standing on shore, not hooked in, with the harness in the right position, the hook will whack you in the balls if you drop it.

Here are a couple of pics. The second one is to see the hook in the open position for those not familiar with the SureFire spreader bar hook. Yes, I know my photography skills are second to none.

Wichard is a brand name. They produce a whole range of chandlery including a variety of QR`s

There are many QR types.

A "pelican" type hook tube type for kiteing cannot jam and some types are found on some leashes and is the best of type for the application of a quick release that cannot jam and be used under any load. I doubt this is the QR you are using!

Try to be more specific if you want to be more successful at getting your point/opinion accross.

That's a GOOD idea !!
I once owned the SureFire spreader bar, " until it broke sending my kite along
with the leash attachment into a light-poll in San Diego".

So i had made a bar with a loop instead of a QR which gave me 3 inches
extra travel in sheeting because the plastic covered loop was Way smaller.

All i need to do is Add a donkey-dick to secure it to the V-7 hook
(didn't need it with the SureFire), and i can use the QR on the V-7 cord that's already in place!!!!

I'll get a picture of it today & edit in later, Off to Fly a Paraglider now.

Bille

PS:
--Kazi-- YES it's suppose to roll, (Ya got it Too tight)
Use Locktite in the Female side of the threads then tighten it up till it stops to roll --- then back it
off till it does.

I am familiar with Wichard. I have their catalog and have looked at all of their QR shackles. I picked the one I linked to because it looked like the model that would most closely perform as well as a control bar QR. Some of the other models have been know to jam in certain elements found while kite boarding (sand) and not while sailing.

i appreciate your input, but, I am not sure what you mean. I think QRs should be integrated into spreader bars instead of control bars. This would save $ and while not standardizing QRs in the industry it would help work around the problems with the lack of standard control bar QRs. My design was just a suggestion for one simple approach using off-the-shelf parts.

hahaha no worries, nothing wrong with improvisation when you get it right!

RRD type Z had a variation of this about 8 years ago at a guess. A CLoop with a QR and all the kites had a ring( the RRD setup also had a line across half the bar that when pulled set free 3 of the lines to flag the kite as the primary. It was very innovative for its time but I don`t think it made it to the next model, the Type Wave I think!). this type of arrangement was quite popular at the time with improvisors as well untill it was discovered the rings wore a groove into the hinge pount of that type QR (the most common and still in use by a few). When used the rings caught in the groove they had worn. The soft eyes also had the tendancy to catch on the hinge. I liked the idea of the surefire hook opening but it was on a stalk, too delicate and unintuitive to use. You will find the issues trawling this site from a while back which may help you with your wheel. If it looks sexy....cost is not an issue!

Is that even he same subject? crikey!
