teason 0 #4 December 14, 2004 I see that you have a Racer. If it's new, than it's probably the speed bag and has to use elastics. If it's a mod, then their shoud be two strips of 1" box weave sewn across the pouch where the lines were previously stoed. If the Mod was done correctly, your rigger will be undoing a modification that is recomended by the manufacturer. The next rigger who gets your gear may want to charge you to redo it. You need to ask your rigger if the mod was done correctly. You also might want to call Jumpshack and have them explain the virtues of rubber bands over safety stoes. You can also PM Sid. he works at Jumpshack. P.S. when your rigger tries to explain that elastics melt when they're used on brass grommets, ask him what the inside of the safety stoe made of.I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet.

overmyhead 0 #5 December 14, 2004 Thanks Teason for you Info. I wil check with my rigger and I will let you know... QuoteP.S. when your rigger tries to explain that elastics melt when they're used on brass grommets, ask him what the inside of the safety stoe made of. What do you mean? Safety stows made out of rubber too? so why don't they melt? does javelin have the same rubber safe stow. Quote Share this post Link to post Share on other sites
sundevil777 102 #6 December 14, 2004 The inner portion (inside the sheathing) of the safety stow is basically rubber band. So, if the outer sheath was worn away, you have...People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired.

Hooknswoop 19 #7 December 14, 2004 Quote Safety stows made out of rubber too? so why don't they melt? with safety stows, the rubber material doesn't come in contact with the grommets. If the outer material is worn away, then the Safety stow is very old and needs to be replaced. Derek Quote Share this post Link to post Share on other sites
hookitt 1 #8 December 14, 2004 QuoteIf the outer material is worn away, then the Safety stow is very old and needs to be replaced. To add to that, it would likely never happen. The bands inside would break long before the sheathing would wear out.My grammar sometimes resembles that of magnetic refrigerator poetry...

teason 0 #10 December 14, 2004 Actually, I believe it is when the brass begins to oxidize that the rubber will break down. The oxidized brass can get in to the safety stoe, breaking down the rubber. The safety stoe is, however, quite robust and to be honest, I don't think faliure with proper storage and maintainance is likely. As for the Racer, replacing the e-bands at every repack should ensure elastic integrity. To answer a previous question, yes Javlin, like all US manufacturers (Jumpshack Excluded) uses safety stoes made from elastic bungee cord. It has been in use since it was introduced by Para-Flite in the early eighties. It is said to have more retentive force than conventional elastics and is said to be less likely to cause baglock. This is, however, up for debate as proper mil-spec elastics are designed to break to prevent baglock and the safety stoe will not. Safety stoe rubber can also degrade from heat (like the trunk of a car) and from oxidized brass. Because the stoe is sheathed, the degredation may go unnoticed. Ohhh ... this could start some good debateI would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet.

riggerrob 643 #11 December 14, 2004 First-generation Racers and last-generation Racers use rubber bands to close their free bags. Degradation of rubber bands only gets dangerous after 2 years in hot climates. We hope that you get your reserve repacked more often than that! Hee! Hee!

bob.dino 1 #17 December 15, 2004 Ten minutes with google. Thought process: 1. Search for "Mil spec rubber bands". 2. About the 7th result is dscc.dla.mil which appears to be a store of information on miltary specifications. Click it. 3. Not much there of interest, so try the "Document Index" link. 4. On the resultant page there's a link to the Document Automation and Production Service. 5. Type "RUBBER BAND" into the ASSIST search engine and see what comes up. Technology is wonderful, isn't it?

Hooknswoop 19 #25 December 15, 2004 Quotewithout shopping for the best price - I bought them from JumpShack. Is that the only source? How do they differ from 'normal' rubber bands that you can get from Para Gear? I would really like to see the mil-spec on them and compare the para-gear rubber bands to the mil-spec requirement, see how they stack up. I'm glad I don't have to deal with this issue since I won't pack Racers. I'm just curious as to the differences. Derek Quote Share this post Link to post Share on other sites
