is an attachment between your wrist & the depowered kite (retains your kite
after it's been released). Wrist-activated release is an attachment between
your wrist & a snap shackle release mechanism (in order to activate the
release of the kite).
>. two wrist leashes is too much!There's really never any reason to attach the kite leash to your wrist (just
attach it to your harness or spreader). Attaching the RELEASE to your wrist
makes for some of the safest systems, since you never have to fumble around
for a release ball. Next safest I can think of would be having the release
line attached to the end of your spreader, so when you're fumbling, it's
always in exactly the same place. A problem with those two systems is that
they prevent the snap shackle from swiveling, AND they prevent "reversing"
the shackle (so it can "snap" directly onto the spreader hook).

hold with constant tension. Believe me, if it's at all possible to make it
catch it will happen when you least want it to. Maybe wet or sandy line
could stick, even if clean dry line doesn't. I don't think it's worth
rising life & limb.

release, one to pull the line/ring & the other to keep the shackle from just
rotating when that line is pulled.

could always just replace that part of the trim line with something slightly
thinner (it doesn't need to be special line to run through the bar), or make
a small loop to lark's head the closed end of the shackle onto the existing
loop. Sure you'd be adding a small piece of line, but you'd be eliminating
the bigger, heavier, more costly chain connector.
- Okay, I had the day off for court (which I lost to the tune of $980.00
arrrgggghhhh...) and got the photos after flying the kite for an hour,
or so this afternoon. Gusty winds today. 20 mph, then 3 mph. Changing
directions 90 degrees every 5-10 minutes. A pain in the butt trying to
work the edges of the window. I did get lifted quite a bit (4 foot air
at the most once) but it was not due to my wanting to.
Four new photos and I got rid of a couple old ones (the four new ones
start with an "X"):
1) xstopperball - depicts the lark's head I made with the LE line to
attach the little knotted line through the stopperball approximately a
LE length from the O-ring (in next picture).
2) xpulley - shows the modification to "diagram.jpg" which eliminates
the extra O-ring at the pulley and feeds one of the lines through the
top loop with the O-ring preventing it from feeding completely
through. The wrist-leash (which as you said can be attached to the
harness) would be attached to the Oring so that if I let go of the bar
and pull the stopper ball on the snapshackle (next photo), it will
completely depower the kite and leave me free.
3) xscrew_gate - Shows the screwgate on the harness spreader bar and
the snapshackle between it, and the large O-ring lark's headed over
the trim loop. This way, with metal on metal, the snapshackle cannot
get caught on the O-ring at all. Should be a smooth release every
4) xscrew_gate2 is just the same but a different angle.
My comments: Works really well. One thing is that I plan to do a
wrist-activated release as you mentioned, or thicken the grab-ball
line with either the PVC covering or thicker rope so that the rope
does not flop around as much. One thing I didn't mention about the
wrist activated release (or maybe I did and forgot) was my rotator
cuff injury. With that, I feel much better with the grab ball
approach, since when I first had it set up on my wrist, with the
amount of line I had to leave my arms free, to relase the snapshackle
was aggravating my shoulder.
I'm also going to draw up with the computer CAD software a better
diagram that is not a photo so its more easily read, with better
comments to help others. I'll put in the options we talked about. Let
me know what you think so far. I think its pretty good (always room
for improvement but SOOOOOO much better than what I started with,
which was NOTHING). I feel much safer, but realize there are still
many uncertainties and will continue to test/modify as you suggested.

(even if that's really a "captured" clove hitch - as pictured in my "Mel's
Stuff" group folder).
Here's another idea for a stopper in the middle of a length of Q-Line: get a
CHEAP plastic ring (69 cents at www.westmarine.com # 283848, Ronstan #
PNP52C), hold the line at the point where the stopper needs to be (to stop
the bar from sliding too far up towards the kite), fold it AS IF you were
going to tie a loop at that point (but don't actually tie it), & just feed
that loop through the ring, over the end & back, just like you would if
there was a knotted loop in the end of a line to lark's head around a ring.
Cheap, light, clean & easy. Let me know if that doesn't make sense.

> top loop with the O-ring preventing it from feeding completely
if you want, just lark's head the end loops over the appropriate rings. If
the sewn loops are too small to go over the ring, make your own larger loop
by just doubling it back into a lark's head. In other words, take your tiny
sewn loop & form a big lark's head out of it. Now feed THAT loop through
the o-ring & over the end. That likely didn't make sense either!
By the way, once you stop adjusting it a lot, you can replace the pulley
itself with an o-ring.

the safer wrist release, it will also be "metal-on-metal" with the trim loop
lark's headed through the fixed end of the shackle (looks to me like your
line will fit), & the open end "snapped" directly onto the spreader hook.
Keep in mind you still need to test the release (try to MAKE it stick),
because just "metal-to-metal" isn't enough, if the metal's bend radius is

easy to fly one-handed with EITHER hand (& use the other to grab the board).
Of course with an ARC in steady wind it takes NO practice at all to fly NO
