skybytch 259 #3 February 7, 2002 Depends on what you want. I've used short pieces of suspension line for pull up cords, but for everyday main packing use I like 1/2" - 3/4" wide binding tape. pull and flare,lisa--What would Scooby Doo? Quote Share this post Link to post Share on other sites
mikefarmer 0 #4 February 7, 2002 I like gutted out dacron suspension line. The cute ones you can get at boogies and stuff seem to wear out a closing loop quite fast.Missy the 225 lb. Meat Missile Sky World Quote Share this post Link to post Share on other sites
DBTECH 0 #5 February 8, 2002 I 'was' using the tried & proven type IIA coreless-flattened line, (formally called--PC crown line) for pull-up cords. I'm now using 550 lb Spectra that is configured into a continuous loop that is 17" long laid flat for a pull-up cord, and I love it, big time. I'm also using 1000 lb Spectra for my closing loop--seems much more durable than type IIA Nylon line. (also, pin pulls easier with Spectra) Dave Brownell Quote Share this post Link to post Share on other sites
PhreeZone 15 #6 February 8, 2002 Dave, What do you think about using Vectran or HMA as closing loop material? I'm thinking about putting 825 closing loop on the next time it needs replaced, what do you think of 825 vs 1000?Murphy's Laws of Love - If the person isn't taken, there's a reason for that...

Spectrejumper 0 #7 February 8, 2002 I invested in a Powertool, and I couldn't be happier. Well, if the rig packed itself I'd be happier but we all know that's not gonna happen. I know Paragear sells them, there's also an ad for em in Parachutist every month. They're $15 or $17. It's a piece of Spectra attatched to a stainless steel rod. People will argue that you could make one for a lot less, but I'm lazy. It makes it much easier to close a rig with a tight closing loop, and it seems to help the closing loop last longer.

DBTECH 0 #8 February 8, 2002 I would not approve of the use of Vectran or HMA for a closing loop, as both of these Polymers have poor abrasion resistance, along with a 'brittleness factor.'The following are simple instructions for making a Spectra closing loop.To make a Spectra closing loop--Use a piece of 1000 lb Spectra that is at least 14" long. Finger trap the line into itself from mid length, (end toward end) and bring the loop size down to about 1" laid flat dimension. (use a wire fid/end loop) 'Milk' the line down with your finger in the loop. A 'tack' at the eye bottom is not needed, as both ends of the line will be secured in the knot. Use a figure eight knot for the stop knot. Dave Brownell Quote Share this post Link to post Share on other sites
DBTECH 0 #9 February 8, 2002 Plus the fact that Spectra (Ultra High Molecular Weight Polyethylene)-(UHMW-PE) has a much lower coefficient of friction than Vectran, HMA, or Nylon. I guess that's the reason they call it the 'Poor Man's Teflon!'Dave Brownell Quote Share this post Link to post Share on other sites

DBTECH 0 #11 February 8, 2002 825 Spectra is ok, but 1000 should--'at least in theory'-have better longevity.Dave Brownell Quote Share this post Link to post Share on other sites
Kirils 1 #12 February 8, 2002 Power tool is OK. (I have one) I have heard is cuts closing loops more than a ribbon. Skydiving is not a static excercise with discrete predictability... Quote Share this post Link to post Share on other sites

Spectrejumper 0 #15 February 9, 2002 QuotePower tool is OK. (I have one) I have heard is cuts closing loops more than a ribbon. I always use my powertool when I pack my rig. I just changed from the closing loop that came with the rig because it was slightly frayed, and I was downsizing so I would have had to shorten it. I have almost 450 jumps on the rig. I've never heard of a closing loop lasting that long when using pull up cords. Of course I still flip the line underneath the pin before I remove it.
