  1. Some of the stuff we used to jump I am not sure was made to open, just look cool during the door jam up. But then I do have close to 100 reserve rides. Want to come along for the ride. Sparky My idea of a fair fight is clubbing baby seals
  2. You are right, but that wasn't the question. My idea of a fair fight is clubbing baby seals
  3. It happened to a friend of mine just a couple of months ago. It was reported on DZ.com. Had he been under a reserve loaded to 1.8 he may not have survived. My idea of a fair fight is clubbing baby seals
  4. metalslug asked: "Does anyone perhaps know the origins of the Riser type classifications ? Where do the numbers 8 and 17 actualy come from and what do they mean ? Are they a measurement or simply a reference index number of some kind ?" I responded with: "Type 8 risers are made for Type VIII webbing. It is 1 23/32 in. wide, has a black tracer line down the middle and is rated at 4,000 pounds. Type 17 risers are made from Type 17 webbing. It is 1 inch wide and is rated at 2,500 pounds. The "type" comes from the old MIL-Spec classifications" skydiverek seemed to want to turn it into a debate on the strength of reinforced Type 17 risers. Regardless at what the risers "usually" break at, Type 17 webbing is rated at 2,500 pounds. That does not change by build a set of reinforced risers with it.

  5. What ever you decide to buy keep in mind that loading your reserve to 1.8 probably is not the smartest thing to do. Trying to play "swooper, look at me I am cool" with your last chance can get you hurt or killed. That is if you don't blow it up on deployment. jmo Sparky My idea of a fair fight is clubbing baby seals
  6. One year ago today, I made a jump with 100 of my closest friends and landed at Kitty Hawk, NC. Sparky KH #69 My idea of a fair fight is clubbing baby seals
  7. At 30,000 feet MSL you can up dead in a hurry and not even know it. At 20,000 feet your Time of useful consciousness (effective performance time) is measured in minutes. (5-12) At 30,000 feet your Time of useful consciousness is measured in seconds. (45-75) And these times were developed with the body at rest. With mild activity they can be cut in half. A jump from high altitude, 20,000 to 40,000 feet MSL, is not just another skydive with extra freefall. Sparky My idea of a fair fight is clubbing baby seals
  8. Have used my reserve 10 or 11 times in 2500+ jumps over 28 years. Sparky My idea of a fair fight is clubbing baby seals

  11. I think 2,500 pounds refers to NOT reinforced Type 17 risers. As Bill Booth states, the the reinforced Type 17 risers have a breaking strenght of around 3,500 pounds. "Reinforced type-17 webbing risers rarely break. They have a new breaking strength of around 3,500 lbs. This is not that much less than type-8 risers breaking strength of 4,000 lbs. The real difference is whether you have mini rings or large rings...and the difference here is in cutaway forces, not breaking strength. While properly designed mini-ring risers can easily release even a 250 lb. jumper in a 3 or 4 "G" spin, the problem is that it is harder to manufacture mini-ring risers correctly. What causes any riser to break is usually a combination of a heavy jumper, a hard opening canopy, and no stretch (Spectra, Vectran, or HTML) line. Broken risers on Dacron lined canopies are very rare indeed." Source: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=1301836#1301836 Type 17 webbing is rated at 2,500 pounds. Unless you reinforce the entire length of the riser, it is still 2,500 pounds. The reinforcement is used where the grommet is placed to compensate for the material lost when the whole is made to accept the grommet. And you forgot one of the main causes of broken risers, even with reinforcement. Lack of maintenance and just plane worn out. Sparky My idea of a fair fight is clubbing baby seals
  12. The purpose of the high speed, high weight test are to demonstrate that the test item will not "explode" in the exact configuration for which it is seeking certification.

  13. Continue to enjoy skydiving as much as the last 29 years. And of course don't die, at least not while skydiving. Sparky My idea of a fair fight is clubbing baby seals
  14. I think it is great, wear as many toys as you can afford. Just remember not to count on them to do what you should be doing when you should be doing it. Jump every jump as if you know in you heart that done of these gadgets are working. And when they do, be surprised. jmo Sparky My idea of a fair fight is clubbing baby seals
  15. The highest safe altitude would be about 3 feet. Jumping from airplanes can be hazardous to you health. But you can mitigate the danger, to some degree, at all altitudes by following accepted and proven safety practices. Highest I have jumped is 30,000 feet, several times.

  16. How many of the old jumpers, from the late 60's & 70's knew how to write? How many of them even remember the 70's? Sparky My idea of a fair fight is clubbing baby seals

  20. And what's that supposed to mean? What exacly is your point in this thread? We should only ask the manufacturer when we have questions about gear? We shouldn't bother to post questions in this forum because the manufacturer will ALWAYS give the best answer to every question? Riggers magically know everything and never learn about gear and rigging from this forum? I'm no rigger, so you'll have to speak slowly and in simple words... Dave My point is wondering when it was a rigger pissed in your wheaties making you feel they either don't know shit, will lie about it, or they are just bad people. There are some rigger who have worked hard to acquire the knowledge they have and continue seek more. And it has been my experience the most manufactures will give you honest answers to honest questions. Of course they will tell you that any unique features they have are better, because they believe it or they wouldn't have made them in the first place. Someone once told me, "You can't trust a man who doesn't trust anyone". I am done. My idea of a fair fight is clubbing baby seals

  22. I've got simliar questions about line twists on reserves. I've never had line twists on a reserve, and mine is loaded barely over 1:1, but I have had to chop a twisted up Stiletto. Question is, are line twists on a higher loaded reserve always recoverable, or can it spiral you in? Is the "spiraling in under line tiwists" a function of wing design (highly elliptical) or wing loading (highly loaded)? I'm thinking it's the former, but I've got no experience with highly loaded, twisted reserves. I would hope any reserve would fly straight with line twist until you could kick out. Who's got some info? John, Part of it is aspect ratio. A higher A/R canopy, like a 9, will be more likely to spin up than a low A/R canopy, like a 7 cell. Also, I believe the H/P 9 cells have a a steeper trim angle then 7 cell reserves. Sparky My idea of a fair fight is clubbing baby seals

  24. I have the spec. sheet on 1832D courtesy of bob.dino. It is a 10 page document and covers Type I and Type II. I believe that 11-1-4095 is the drawing number for 1832E not the part number. Pree, you were right, that is the part number. Sparky My idea of a fair fight is clubbing baby seals
  25. It allows the canopy to open up and flatten out. On larger canopies they fly more stable in deep brakes and the flare from 1/2 or 3/4 brakes is better. Sparky I am not an artist, but look at the drawing. My idea of a fair fight is clubbing baby seals
