  1. I know of at least one person who builds (built) risers to spec for an unnamed factory, but would build his own Type-17 without the reinforcing strip for exactly this reason... he'd rather face the problems of a broken riser on opening than the overload situation. Years ago we figured out how to build parachute systems where the weakest link is the body in the harness. While I am grateful that we're not breaking/falling out of harnesses, as long as we are going to have the possibility of openings that overload the jumper's body, we need to figure out how to put a weaker link back in... I agree with Bill that the risers seem to be the best place for it. JW
  2. Not something I'm aware of currently in use, but my thinking is this: - With unreinforced Type 17, it would act as a weak link in the case of a very hard opening. - Currently, the Collin's lanyard is provided (mostly to my knowledge, in concert with Skyhooks) to ensure that, should the RSL side riser break, the other riser would be released prior to reserve activation. - If we had a release system similar to that on each side, such that a break of either riser would result in the release of the other, having weak-link risers would not be as bad a thing. (it would avoid the bad situation of single riser failure and the reserve being deployed prior to the second riser being released). No, I don't know how this would be setup as I'm now saying the "long" side riser needs to pull the "short" side cable... but we've got smart people here... JW
  3. "Well, in all my years I ain't never heard, seen nor smelled an issue that was so dangerous it couldn't be talked about. Hell yeah! I'm for debating anything. " - Stephen Hopkins (RI) "1776" As others have said before, don't let our nay-saying discourage you from trying (carefully) to find a new way... but also look at what has been tried before so as to not relearn lessons (especially those we've paid blood to learn). That having been said, I'm thinking that the simplest solutions usually are the best... how about this: Learn from the: Type 17 risers pre-reinforcing strap. Collin's Lanyards. Solution concept: Dual Collin's Lanyards with main risers designed to fail on overload, where the Collin's lanyard connection point is above the weak-link on each riser. If either riser experiences an overload, it fails, releases both risers and the reserve is free to be deployed (if not all ready by RSL/MARD). (notice, I said dual Collin's lanyards, NOT a single dual-connected strap like the Racer RSL) Hang-on ...let me get my kevlar on and adjusted... OK, FLAME ON!! ;-) Debate! JW
  4. I had a ~18y.o. closet-queen PEP brought to me once, table total (50-lb pull wouldn't dislodge it). Original factory pack job on it (seal matched card). Searched for SB's, didn't find anything but called the mfg. and found that there was a SB so old it hadn't been posted online (SB came out just after this rig was made) about a housing change that could cause exactly this problem. Remedy was to move the RC housing back a bit from the first loop. Simple, but had to be chased to ground. JW
  5. Normal practice is that the pack data card _should_ stay with the reserve canopy, though I have also heard of the other extreme attitude that "the pack data card need only show the most recent packjob, so who cares" Personally, I would like to have the standard phased in that each major component has its own service record. Yea.. I know, the devil's in the details on that idea... but still I think it would be nice to know where the container has been, and whats been done to it as well, even if the canopy changed. BTW - yea... links go with it. even if they're shot and need replacing (in that case, ya send 'em and note their deficiency). If for no other reason that keeping things neat. (edited to add... OK, this is what _should_be_ IMHO, but used... you never know if they don't say it) JW
  6. Difference between the rich slobs who pay you, vs the rich snobs that expect you to pay for their fun. Fortunately I learned early on as a rigger that if you are NOT rigging to earn a living, you can choose for whom you rig... I don't pack "expensive FAA required seat cushions". I inspect, repair, repack, and train my customers (primarily pilots) in the use of a lifesaving device. If they don't believe that's what it is, there are other riggers out there that are eager to take their money. Just my $.02, JW
  7. I know of one open-cockpit aerobatic team that was in part sponsored by a PEP manufacturer. They would leave their rigs in the cockpit all day/every day/all show season. As I got the story, the mfg pulled the sponsorship after the rigs proved shot (UV on the harness) within 2 years. They advised the team to at least cover them when not in use (even if they stayed in the cockpit), but no go. Mfg got tired of giving them new rigs every 2 years for such a non-reason, so they quit. JW
  8. Several started to indicate that they were going to, but it looked like a game of chicken... If you do, I'll advertise mine have a longer life than yours. I _think_ (Councilman would know better) that its why some looked to PIA to set a standard... that way everyone is in it together, no one is the bad guy with inferior products and it comes from one authoritative source. And if they do, that helps going forward, but does little for the ones already out there with the FAA seemingly saying "once they're certified TSO, you can't add a life limit..." JW
  9. Given that accidents happen, and lawsuits often look for anyone associated with the situation regardless of common sense... let me ask you this... Judge/jury/widow look to you and the prosecutor says "so, the very manufacturer that made the gear, and is needless to say, the MOST familiar with the workings of their equipment won't even service their own gear at that age, and yet, YOU, an independent field rigger decided, on your own, that you know their gear better than they and put it back into service KNOWING that they wouldn't have, and had specifically recommended against it. " Remember, it doesn't take an actual error on your part to get to that point. And it doesn't take much to move opinion from the fact that the pilot got out too low for any 'chute to work, to focus on the detail of your disagreement with the mfg on whether 21 years was too many... I'm not telling you what to do, but it is worth considering. Just my $.02 JW PS - if memory serves, some (all?) of the EU life limits emergency 'chutes to 15 years... can someone update/correct me on that??
  10. If just looking for a loft-rig (practice and cert) there are still some Starmaker's and mil types around. Ebay has been a great source for me. If you're looking for the market as a rigger, there is only one civ chest rig I'm aware of (Jump Shack to go with a base rig for use in planes), but there are several mfg's of seat rigs for the war-bird pilot community. Not sure if the new owners are making any, but Jerry's old company had gone through the process so that he was making lap rigs, and there are a handful of DPRE's that can test that as well. JW
  11. Jerry - From a US legal point of view, I completely agree, most especially when dealing with Racers/Reflex and Softie/Butler/Strong Longs, but changes after its left my hands can be made on most any rig. And inadvertent contamination/mishandling certainly can. However, from a rigging/learning/best-practice point of view, I'm always looking for the before/after and the why. jeanneretjerome - I find your numbers very interesting and contrary to my experience... most the time I find lower numbers upon return (180 day cycle, but many pilot rigs only return each spring). I attribute lower numbers due to canopy settling/compression and stretching of the closing loop(s) during wearing. The only situation I can immediately think of that would counter that (assuming your not dealing with a field adjustable system like Racer/Reflex would be if you were using the vacuum packing method*, in which there might be some expansion after the pack job is complete... Would be interested in seeing more of your before/after/conditions/system-type data and what you conclude... *not a technique I use or endorse, simply have heard of: When packed 99% (final temp pin in place, prior to ripcord) place entire rig in an appropriately sized vacuum storage bag and suck all the air out, let stand, then open vacuum bag and place ripcord. Note: There are warnings from the AAD mfg's about using this technique. Consult the appropriate mfg and others experienced in this method before attempting. My thought is, if you need this you may be working with too large a reserve for the container. I'll See your $.02 and Raise you $.01 ;-) JW
  12. I used a Cypres temp pin to catch/lock the deployment and it seemed to work fine for me. I'll look for some fine piano wire, but meanwhile the suggestion betzilla made to use dental floss threaders looks like it will work well to thread the pullup cord back in when/as necessary. JW
  13. I took this as sarcasm... (hope so). To the jumper in question... good job. fight for you life... you might just win. JW
  14. First -sorry for the footnotes here... I can't help but include many lessons learned for the young rigger out there... so they avoid stupid/honest mistakes I've done, seen or heard... I do a few things, none of which seem to cause issues (first priority) and seem to help (secondary consideration): First - when I clean*/lube* the cutaway cables, I then use the same cleaning/lube cloths on the reserve ripcord. Just as with the cutaway cables, the lube should be _thin_ coat... don't soak it. Second - I use the Cypres lube on the loop IACW the mfg instructions. Third - I run the center of my pullup cord* (cypres loop material) through the Cypres lube cloth (to help not remove the lube from the loop as its drawn through, reduces cord-on-loop friction) I do NOT use the Cypres lube or WD50 on the ripcord or cutaway cables as I believe they are too thick and too likely to attract dust. Just my $.02 JW *Lessons Learned/Heard/Observed: - per Booth's recommendation I clean with Ronsonol* Lighter Fluid and lube with Ace Hardware Brand Silicon Spray Lube* - Ransonol brand sells both Lighter Fluid and Multi-Fill Butane Fuel, both useful to those refilling the two (different) types of lighters, but to those of us who rarely use, must let refill lighters... they are different things. You want the yellow squirt bottle. - Silicon Spray Lube is in a can that looks remarkably like the Silicon Spray Adhesive. It is highly recommended that you make sure you know the difference before using... (this told me by a rigger of the highest level who made that very mistake) - Cleaning, and lubing with these items is simple, but can be f-ed up I'm sure... spray some lighter fluid on a clean cloth (paper-towl) and then run the cable through it. Repeat in a different wet part of the towel until you're no longer leading dark streaks on the cloth. Spray a second cloth with the Lube and draw the cable though it once to apply a _thin_ coating along its length. - If you use the Cypres loop material for your pullup cord, finger-trap ~6" additional loop material into the middle of your pullup cord (completely encased, so the middle section is thicker with no ends sticking out). It helps open the loop a bit to get the (temp)pin into the loop. SSK indicated that this is approved (per Cliff at the time). I do recommend shifting toward one end when moving it through the cutter, so that you're not trying to pull the full doubled u-turn through the cutter. - If you find that you are staining ANY part of the rig (flaps, risers, harness, D-bag, canopy) with the lube, STOP!!! You are using WAY TO MUCH!!! Get help from someone who can show you how to do this right.
  15. Agreed, but it is the mfg supplied part, and removing the scratches (if problematic) is better than not. I'd not advocate trying to apply any after market hardening. We've had problems in the past with metal components being processed/treated in ways that turned out to be bad in the end. I personally saw that part of his video as an appeal to the rig/pin mfgs to consider R,D&T into having a harder layer. If you are qualified and have the resources to do that R,D&T for the industry, GREAT... just don't experiment on customer rigs. JW
