  1. Yeah - the sleeve could have been secured by Velcro.
  2. Yes, I saw one. (Rodriguez rig without hardware for chest and leg straps). It had (pretty sure), flat pieces of smooth aluminum, pretty long, (not plastic) that slid inside of the leg and chest straps. You slid the aluminum insert along until the strap fit you, then folded it back and secured the insert by laying it flat and "locked" it in place with a fabric sleeve of some type, and the sleeve was secured by elastic or friction or something.. (this was 40 years ago) Pretty cool idea - actually. Never saw it jumped, and don't know whether it would have held; but that guy was a thinker and an innovator.
  3. Buy a Mohoc camera. Maybe it's called Mohawk - whatever. t's called - it's about as snag proof as can be mfg.

    "…while state law largely trumps federal law in most contexts..." . Nope. Bad info.

    Who's going to PIA?

    Who is going? One group of attendees are riggers seeking the "Continuing Rigger Education" certificate for attending the required number of hours of rigging related seminars. For starters. Also, riggers who dislike knowledge stagnation in this technological endeavor - known as rigging- who like to keep up with the latest innovations in equipment and who benefit from the knowledge in the seminars.
  7. So Yuri. You'd be a happy customer buying a counterfeit copy of someone's invention. And you see nothing wrong with copying someone else's invention and using for yourself. Wow!
  8. The term "Reverse Engineering" is wordsmithing to cover what it really is: Stealing. If one's intellect and design skills are so poor that they can't make a product of their own...well, I guess they just steal from the guy who did. And to make stolen copies and sell them?...shame on you.
  9. Hookenswoop is correct. The installation must be noted on the data card, the rig re-sealed. Although it can be done that way, it is a very bad practice. This new rigger is now the certifying rigger for this assembly and assumes all responsibilities for it. The new rigger is now responsible for everything inside that reserve pack … and any other defects on/in the rig, because when the new rigger records the info and puts his seal on it, it was that new rigger's responsibility to thoroughly inspect the entire assembly. Including the main parachute if it is still attached. Say the main parachute is installed backwards or a riser is twisted or the main is not airworthy... or there is something about the H/C that makes it not airworthy. If the main was attached when the "just installed the AAD" rigger got it, or the H/C is not airworthy this new rigger has just signed on to take responsibility for everything. Can the new rigger argue that he isn't responsible for all of the other things? Yes. He can argue that. Can the new rigger argue that he is not responsible for inspecting the entire assembly? Yes, he can argue that. "I just installed the AAD. How was I supposed to know the other things were not routed properly or were not airworthy?" Yeah, go ahead with that defense; but not inspecting the entire rig, including the main, if it was attached, is an unethical and whiny and losing argument. Although it is rare, survivors can sue. I'd hate to be in that chair when the fingers are pointed. And even if you beat the legality...I'd hate to be that rigger when other skydivers talk over the campfire about how you gave an unairworthy rig back to the jumper and he went in. All the while you are defensively repeating, "I just put the AAD in and I never looked at anything else...How was I supposed to know all the other stuff wasn't good? etc". Yeah - right. Ethics are just an academic subject, and a rigger's responsibilities are just words; until the consequences fall. Never do this.

    Fingertrapping 550 cord?

    Sheath diameter of 550 cord is too small to eye splice/finger trap 550. I would say that the only way to create a reltively smooth eye splice in 550 is to mimic the usual sewing stitch - the double throw ziig zag stitch. It is used above the "L" bars on parachutes, but only as a back up to the usual clove hitch or double half hitch on the "L" bar. If you use the "joint efficiency" formula in Poynter I, I guess you could use the double throw zig zag stitch using E cord/thread (8.5 lbs) and sew the required number of stitches to equal 550 lbs. 68 or 69 full double throw zig zag stitches. And the zig zag stitches would have to be wide enough to bite into the whole 550 cord - not just the sheath. Just guessing here. Haven't tested that. Works on paper anyway.

    a question about old cutaway systems

    I never heard of an R-2. But...I have many jumps on a rig with R-3's. Basically just a standard metal Capewell riser hardware holding device which replaced the "two shot" and "shot and a half" release covers. It was pretty nifty and was used for a quite a while (by all of the "cool jumpers) (such as myself ha ha) before Bill Booth's 3 ring - which replaced the Capewell base hardware entirely. The R-3 was just fine, but it did require your releasing both/each sides. Of course the 3 ring was vastly superior and as soon as it came out the R-3's disappeared quickly. Since the R-3 was built to release from a military style Capewell "base" the 3 ring required a new harness design. The military harnesses went out the window very quickly. Not a bad thing.

    Falling out of a Harness

    I recall Bill Booth's *comment from years ago, "There is no safety feature that can't be defeated". *Came from memory: I think I got that right.

    Good skydiving songs

    "Hey Freak Brothers" by the Booze Brothers And, check out the songs in the movie "Skydive" ("I want to Skydive")and the main song in "Wings" movie. These are the only actual skydiving songs.
  14. "Banana type"? Rather then make up a wierd term it wold be better to use accepted nomenclature: chest mount.

    pd pulse

    Uh "less than stellar flare". I'll say. Only half the flare power you need/expect. It is a dud. Use it for a car cover.
