Not arguing with you but I thought it was more like 5.5? Anyone...?

If the breakcord that goes through both the red loops prematurely breaks then there is nothing to back it up? Or am I wrong and is the picture just a little hard to see? Chad, did ya get my PM? I'm lookng at flight info and need to know when you'll be in Twin.

From bridgeday.info "Registration will officially open on July 1, 2005 around 2pm Eastern Standard Time (19:00 GMT). "

I'm still trying to figure out why he planned on going in the water with a camera on.

Ok, sounds good. So, who is in need of a get well carrot? It's really cute. You must pass it on and hopefully you'll post something here letting us know you've passed it on and to whom.

What do you think about having one carrot that gets passed around? When someone breaks themselves they get the carrot for a while or until someone else breaks themselves and then they send it to them and so on. We could have a BASE jumping community get well carrot!

Uh...are you sure you want to do that? You may be scarred for life. Trust me, I've actually hung out with the guy.

Clicky

Yeah, I was thinking the hook knife wouldn't cut through the risers in one cut.

If you're using slinks couldn't you just pull the cutaway cable and then hack away at the slink? Wouldn't that be easier than hacking through a riser? I don't know I never seen a slink in real life and I'm not exactly sure what they're made of. Yes I've been out of skydiving for that long!

How about a zip tie through the little ring, as far up as it would go to help with leverage, instead of through the white loop? Edit to add - This way if the white loop breaks OR the yellow cable gets pulled the 3-ring still wouldn't release.

Thanks for posting those Tom!

Yes I would, yes I would!!!

Does this mean I need to return your extra rings back to you? They're still on my harness.

I knew I wouldn't do a good job. Yes he did. I deleted the e-mail he sent me saying what he did exactly. He tried a few things if I recall correctly. The one I do remember is that he used thin string of some type to artificially set the brake instead of putting it through the eye of the brake line. On opening the thin string broke and blew the toggle. He said it worked as designed and the toggle was held in place by the keeper ring which then cutaway when the toggle was released. I'll shoot him an e-mail to see if he can post some pictures of the setup. Does Tom even own a digital camera?

Ok, I’ll try not to make this too long. First let me explain the intent of the idea. A while back I read about Faber’s accident landing rear risers and ending up with a broken leg. I then heard another one or two similar cases. So, I figured landing on rears was a bad thing. I didn’t know at the time that we should all practice this and be proficient at it. Then I thought to myself this would be very bad if it happened to me one day in the future if/when I do ground landings. My idea was to attempt to eliminate blowing a toggle on opening but still make it just as easy to clear a line over when doing slider down jumps. I talked to several people, a rigger and even to a BASE manufacturer and no one thought it would be a great idea for the masses but maybe a good idea for me. Now I’ll do my best in trying to explain the setup. Essentially the keeper ring is permanently on the brake line and is cutaway each time the brake is unstowed. If you were to have a brake line blow on opening the toggle would get pulled up to the keeper ring and stay there. The moment you pull the toggle down you cutaway the keeper ring. This keeps with the idea of the LRM in the fact the even using these risers, if you have a lineover all you do is unstow the toggle, automatically cutting away the keeper ring, and toss it. The keeper ring is held in place just like the small ring on a 3-ring release system is. A white loop goes through the ring then through a grommet and then a bit of standard yellow cutaway cable goes through the white loop. One end of the yellow cutaway cable is sewn into the toggle but protrudes out the side and goes up, through the white loop, and the free end is inserted into a sleeve. Maybe Tom could post a picture of the risers. He still has them. Tom’s graciously been the test jumper for me (20 slider down and 10 slider up so far) and he seems to think they work pretty well and that they may have their own little niche. I’ll let him comment on that. There are downsides to this system. The biggest one I can think of is that it does make setting the brakes a little more complicated and takes a little bit more time. That’s the best I can do in describing the setup. I’ve now gone through several revisions of this post and this is as good as it gets! If you’ve got questions about how they felt or functioned you’d have to ask Tom (sorry Tom) but in an attempt to keep Tom less busy if you have any questions about their design I can probably answer them. It’s funny, now that I think I’m done doing slider down jumps this idea seems moot to me.

I guess I'm with ya. Although I've tried it a few times before when I was bored while underwater (my commercial diving days) I didn't like it that much. Maybe another go will change my mind!

I was just messin' with ya. But all in all you did do a jump from 120' successful or not.

Wait a minute now Nick. Didn't you do one off a 120' bridge somewhere is New Zealand?

Hmm..I stand corrected.

***Justs thinking off the top of my head. I haven't thought all this out but...*** Although you have to remember that the air spilling out the bottom of a non-vented PC and the same amount of air spilling out the top through a vent isn't necessarily the same. It takes energy to turn the air around 180 and spill it out the bottom whereas that energy isn't required when it goes out the top through the vent. I'm wondering if the time the air stays in the pilot chute longer (needing to turn around and spill out the bottom) or just the energy required to turn it around (opposite reaction being the topskin pushing on the air) creates more drag than a vented pilot chute. Ok I'm tired and I'm going to bed. Did any of that make sense?

I hated my fluid dynamics classes. Both of them!! Wait a minute....aren't you just a video game geek!?!

Clicky for those lazy people.

I would think a vented pilot chute would be better for those shorter delay jumps where separation from the object is less and on-heading is that much more important. There is obviously a limit to this. I doubt one would use a vented pilot chute on sub 200' freefalls.

Yeah, congrats Jaap. Too bad I didn't go with you all down to that "A" but I would have just fallen asleep just like most others on the trip.
