I saw one riser come off in a clip but not sure why. How could this happen? If you have a solid handle atachment and the cable is under binding the whole way to the risers your good right?

Broken white loop would do it.

besides the obvious (damaged loop, damaged riser, misrigged)...

if the tape that forms the softhousing isnt sewn together really close to grommet, the gap between the end of the housing "tunnel" and the grommet can get rather big, exposing a lot of yellow cable. on hardhousings this is only a few mm and therefore really hard to pull the yellow cable out, if a softhousing isnt stitched up properly you can easily stick a finger inbetween tape and yellow cable and pull the yellow cable out cutting away the riser.
i know one jumper personally that had an unintential cutaway and he told me he thinks that was the reason. (loop was intact) i suppose this shit can really happen, and i can see this happen when you have your hands going for the risers during deployment, also i think if the gap is big enough so you can cutaway with one finger without fiddling around, a gopro screw or other snagpoint can do the same...

another issue could be unproper housing lengths, that has been a problem on skydive rigs ( http://www.unitedparachutetechnologies.com/...cutaway-housing).pdf
). the same applies when using softhousings, if the housing on the right side is too short (see pdf) the loop is loaded over the housing.

ive found both issues above on baserigs. the problem with the too wide open softhousings can be easily fixed by stitching it up as close as possible to the grommet.

one more thing, if the yellow cable is recognizably bend or dented where the loop sits, something is wrong with the setup (too short housing, too short loop, wrong 3 ring geometry, etc...) and therefore putting too much load on the loop.

take care!
ciao!

what rig is that Hirschi?

Post clip please

Harness Container under full load & stretch during opening shock .
One Cutaway Cable, on one side, cut to short but not noticeable till harness under load stretch and stretches cable-housing under load with it . Then pulling the improper length cut cable, out past the loop & grommet . Cutting away the Riser on one side only .

Good pictures. You have assembled your 3-ring in the manner recommended by mfrs such as Apex:

I just wanted to hear people's ideas, on why we don't reverse the order of the grommets. Note how the white loop passes through the small ring, then the riser grommet, then the cutaway housing grommet, in that order.

What if the housing grommet under-layed the riser grommet, i.e. the riser grommet was sandwiched between the housing grommet and the cutaway cable.

Strikes me as being a little more secure, but I am not a rigger. I am sure smarter people than me have applied their brains to this, and I wonder what the reasoning is for or against each method. I have jumped rigs configured both ways and never had a problem with either.

The whole reason (I believe) that the riser grommet exists is as a stopper so the housing grommet does not get folded or sucked up under the third ring. You can see how that renders it completely ineffective, essentially allowing the third ring to pull the cutaway for you. Routing it the other way, with the riser grommet on top, would almost certainly assist in the housing grommet falling underneath and/or slipping inside of the small ring.

..." I saw one riser come off in a clip " .

Can you say what a ' Clip ' is ?
Clip - movie Vid recording ? .. Clip on tree limb on landing ?
Is this skydiving or Base related ' Clip ' . of a single Riser release that you saw ?
.

Without actually seeing the clip, most likely a broken white loop, or a reverse routing of the cutaway cables.

CF36,
I have thought about this for a few days and examined my own gear and it's still not clear to me how that problem could happen. On mini rings, the housing grommet appears too big to get sucked into the smallest ring. Even if it did, the riser grommet is still there holding the directional pull in place. Can you illustrate for me how the 3rd ring could pull the cutaway? Maybe I'm just dense.

Under this setup I kind of like how the riser grommet keeps the cutaway cable and housing from flopping around so much. Under the "official" way I have more concern about cutaway cable exposure, and risk of being yanked out by something inadvertently.

When the riser is loaded, does the cutaway housing remain in place, or does it pull on the grommet, potentially moving or kinking the yellow cable?

I think that it may depend on your specific risers and container, but I do remember hearing that Todd had once given a safety briefing at Kjerag in which he'd pointed this out as a potential error. Unfortunately I can't recall exactly what the issue was. If I get a chance I'll try to call him and ask at some point.

I thought about it some more too... I can see where a mini ring keeps the grommet from moving through... but still doesn't keep it from moving around... this grommet may sit lower than the fixed length of the grommet on the riser... causing pull tension on the rings or loop to be at a less effective angle... regardless, I think the whole issue could be negated by using a system like the one depicted in the following picture.
Put a housing on the riser that comes down a bit further and then sandwich the cutaway housing in place. This exposes only like 1/4 inch of the cable optimally...and it keeps the cutaway housing from floating out as far. would this do the trick?

There was a fatality in Ukraine on a skybase jump, missriged 3-ring caused unintentional cutaway on deployment

After my first yeah of BASE I removed my cutaway cable and installed 4 loops of 2mm tech-cord in the three ring. I did not like the idea of a release in my BASE gear, or the need to check and maintain it. I did another 200 or so jumps with that configuration. On my new gear I ordered integrated risers and have about 300 jumps with that rig.

I'm not saying it's for everyone, but in my head the cons of a three ring outweigh the pros. Don't land in the water, don't land on the stoplights or trees. There are a few jumps I would install the three-ring risers on my rig for but it's been a long time since I've done a jump like that.

I was on a low guyed tower and doing a roll over I hit it with the most perfect 180 I can imagine. As my canopy was ripping on a wire I chopped and ninja money'd the tower with one arm. Not a scratch on me, destroyed canopy (lots of jumps on it before I got it then I put a couple of hundred on it so it got its use) and a realization that the cutaway saved my life. That said, I'd still take integrated risers and just not do roll overs off guyed towers.

I have 2 custom rigs with integrated risers.
In total they have around 600 BASE jump.

If I do ever need to cutaway then my plan
is to cut my $20 Slinks using a hook-knife.

I have & will jump a rig with 3 rings but I'd
never ever choose that option on a new rig.

I have Smart-Tarded a few freestanders but
Rollovers with wires... too Pikey for me

I also love jumping integrated risers but still get night mares of a jump where I almost drowned. If i didn't have a cut away on that particular jump I wouldn't be here talking shit today.

first hand information:
it will take much longer to cut s-links with your hook-knife than you would expect...

I have no damage to my yellow cable after a dozen SU and SD jumps in this configuration.

On the ground, it looks like the housing grommet "floats" sufficiently enough to prevent pulling on the white loop from any direction. In fact it is mobile enough, that this is the reason I wanted to restrict it's mobility somehow, in the first place. But I agree it would have to really be checked under a load. And ideally under maximum opening g-forces. I will take note during the next chance to load the risers.


I will ask as well!

Todd wrote me back very promptly, despite a busy schedule. Basically his explanation was that the official way is recommended because that is how it was tested. And the unofficial way has "never been tested."

This discussion made me think of complications I hadn't considered before. Whether I will re-rig my current risers, I don't know.
