smiler 0 #1 June 17, 2005 A lot of people say that double-wrapping mouthlock bungees is a bad idea. I can't find anyone who can tell me why. Anyone got a possible reason? What harm could it do?www.wingin-it.co.uk Wingin' It wingsuit school Quote Share this post Link to post Share on other sites

ps5601 0 #3 June 17, 2005 The mouthlock bungees are normally tighter than the others as you have more lines going through them (remember above the cascade you have twice as many lines as below) and if half your canopy is out the bag this makes them tighter still. Double stowing makes these EVEN tighter, and so potentially could give you a bag lock. On the other hand John le Blanc told me that if they are lose, then double stow them (obviously, if they're not lose don't).

smiler 0 #4 June 17, 2005 Thanks for the replies, but still all I can find is anecdotal stuff about bag locks, which isn't conclusive because baglocks can be (usually are) due to bad line stowage. Can anyone give a logical reason as to why double stowing could cause a problem? Looking on p.341 of Poynters, there's various pilot chutes and a table giving the drag in pounds measured at 120mph, all the figures are over 100 lbs. I don't believe that wouldn't snap a bungee (not tube stoe!), even a doubled one.www.wingin-it.co.uk Wingin' It wingsuit school Quote Share this post Link to post Share on other sites
riggerrob 643 #5 June 17, 2005 I have double-stowed thousands of mouth-lock bands and only suffered one bag lock ... that was back in the 1980s and the end result of a series of blunders. Quote Share this post Link to post Share on other sites

Let's try coming at this issue from the other direction. Why do you want to double-wrap those stows, when you get properly-sized rubber bands that don't require double-wrapping? What do you hope to gain with a double-wrap? Quote Share this post Link to post Share on other sites

I don't believe that wouldn't snap a bungee (not tube stoe!), even a doubled one. Even a PC in just fair condition will produce a 100 pounds plus at terminal. Take any stow band you want and double it or even triple it. Now hook a 100 pound weight to the stow band and try and pick the weight off the ground. I think you will find that the stow band will break before the weight lift up. Bag locks are caused by lines fouling with a stow or the bridle. jmo SparkyMy idea of a fair fight is clubbing baby seals Quote Share this post Link to post Share on other sites
