BUNGEE Shock Cord or Surgical Tubing

The other thread is messy, and people are responding without reading the thread. Basically the OP did a great job but had to multiple times tell kids there are better alternatives.

After research i found this site to be the most helpful:

http://www.divegearexpress.com/hardware/tubing.shtml

But the question becomes shock cord or surgical tubing:

Surgical Tubing:

3/8 inch (good, thicker the better) @ 50ft = $39.95.
This would be all you need, 3 strands @ 16 ft each or 4 strands @ 12 feet each

Shock Cord:
"Shock cord (bungee) is a longer-lasting and more durable alternative to surgical tubing because it is rot-proof, waterproof, and resistant to mold, mildew and UV. Shock cord is constructed of continuous rubber strands with a Nylon abrasion-resistant braided jacket, suitable for marine applications. Stretches 100% of its original length; a piece 12-inch long will stretch to 24-inch."

This seems exactly what we need. Only problem is at max available, 3/16 of an inch is super thin. Thats half the size of the tubing.

3/16 @ 100ft = $38.95
You would need 6 strands of this to equal 3 strands of the surgical tubing (so price point is dead accurate).
6 strands of a 100ft roll = 16 ft each. Once you braid this though it will drop in length marginally, i am going to assume to 9-10 ft (6 strands means alot more weaving).
I found this link to show how to braid 6 strands. It looks fairly simple once you get the hang of it.

http://etherwork.net/ejmtph/recipes/photopages/braiding.html

Once you braid 6 strands at 3/16each your final bungee will have a diameter of just over 1 inch.


I think i am going to buy the shock cord system but my question to you guys is this: How stretchy is the tubing system? It poses alot less work to implement, and the less weaving (less strands) mean you get more length for your money.

Thoughts/opinions/advice!

generally surgical tubing is far stretchier and quicker to rebound than shock cord. they use it on slingshots and think of how well slingshots shoot. your only problem is that 3/16ths is tiny. you would need at least half inch tube braided so that its three tubes to get a good amount of speed.

on the other hand, good shock cord is still pretty snappy and a good deal cheaper. you can do better than scuba diving sites though. ebay is a goldmine for this stuff.

and that shock cord is way thicker than the stuff on the diving site anyways.

So which is better? I dunno about you guys but i've had multiple slingshots break on me... shock cord is better but not as snappy?

yea dont get the surgical tubing unless you plan on using it for strictly summertime...because the tubing that the banshee uses is VULCANIZED latex tubing. I did some research on this and what vulcanized is, is that its chemically changed by like sulfer or heat press.

The surgical tubing is natural rubber on that site... meaning it is not vulcanized and is brittle in cold and melts in extreme heat.

I imagine that the shock cord(aka regular bungee cords) is just as brittle in the cold. This just has the nylon outer to it so it is somewhat protected.

Not trying to damper anyones hopes of making one, but ya gotta know.

So i would go with trying it with the bike tubes because it is basically the same material, just need to get alot of them

yeah go with bike tubes thats what i did and it worked out pretty well and you only need about 9 if road tubes or like 6 or 7 mountain tubes. just go to your local bike shop and ask for their extra popped tubes

I really want to make my own bungee but I will probally be using it more for skimboarding then skiing. The shock cord is waterproof, so I think that would be a safer alternative for me. does this make sense?

I'm almost leaning more towards surgical tubing just because it tends to be stretchier. I'd like to hear from some one that has tried it though.  But look at the 3/8" tubing on that and it is almost a full tube, just a little bit hollow. http://www.divegearexpress.com/hardware/tubing.shtml
I feel like braiding that with three strands wouldn't put too much stress on any of the bands

bad thing about surgical tubing is that it sucks nuts in cold and if it nicks anything that baby will tear like a vagine recieving a black man, just bad.

Yeah I figured that.  In my searching though I found this stuff on ebay. http://cgi.ebay.com/3-8-X-150-Rubber-Rope-Shock-Cord-Bungee-Strap-Tie-Down-/250732396695?pt=LH_DefaultDomain_0&hash=item3a60d0c097 
It is supposed to be like bungee cord used for tying down tarps and stuff so it seemed like a good idea.  It also is supposed to be abrasion resistant and uv protected and such.  I just bought it today and it should come on Friday or Saturday.  I'm hoping it will be stretchy enough

wow good find. that looks like exactly like the banshee stuff. the only thing is that its solid.. idk if the banshee is solid cord or not. and i thought shock cord meant it was like regular bungee cords with the nylon outer... you gotta let me know how this works!!!

I'm hoping it is just like the banshee. My friend said when he held a banshee in a store it seemed spongy.  That would just mean more stretch though, so we'll see how it works out.  They just put in shock cord so it came up in searches.  On the info it says solid rubber and it looks pure rubber. Can't wait to get it! and with 150 feet of it I'm going to be able to make a couple bungees :D

Dang yea ya will. Yea i felt a bungee that someone had and it felt spongy too. I thought it might have been hollow in the inside, really thick but still somewhat hollow. I guess you'll find out. If it works like really good let me know cause im working on a bike tube one right now and its not working a hundred percent.

Hey guys, just got that stuff I posted earlier and made two different bungees.  A 20' one and a 12' one.  I made the twenty foot one so it can attach to a tree or whatever object or to the 12' one.  The 12' one isn't done yet but is close.  I also used 4 strands on the 12' instead of 3 because I made the 20' one with only 3 and it didn't feel like it would pull you enough.  Anyways, I'm hoping these are both going to work pretty well once I get to try them out.

I haven't had the actual bungee material.  It isn't that spongy though and also doesn't stretch as much as the banshee.  I just had those caribiners laying around but they probably wouldn't cost more than 3 or 4 bucks

i made one out of 1/2 inch shock cord. i used three 30 foot lengths, when i braided it i left about two feet at each end unbraided. i took the unbraided portions and wove them back through the braid. this is key because when tension is put on the bungee it tightens up around itself. kind of hard to explain. i will post a pic and vid when i get them. It works pretty good. havnt had enough people to max it out yet. It aint no banshee but works great for not having to build a drop in. im going to try to make another with different material next week, then i will post pics and clips of both. let you guys decide.

Yeah my one I posted before isn't working that well.  Too hard to pull back and doesn't give enough pull.

If your feeling game then this is what you need to make the closest thing to a Banshee Bungee.

First of all you need some kind of rubber much like Banshee use. I would recommend the following.

Insert the following Wish Bones in to your rubber.

These inserts are then tied and made flush with the following two materials.


After you have inserted the wish bones and made them flush accordingly start to begin your braid. Once your braid is finished use rubber to go over the inserts much like Banshee does or try and find a shrink tube that is large enough to over all three tubes. Then use a key ring like metal to connect all inserts together. Finish with carabena or rope and water ski handle.

Bam and the Banshee is done. If people want me to do a photo tutorial then I'm more than happy.

Very interested in making a few bungees.. Do you think a waterproof latex sealant meant for waterproofing objects (Like a Rain-X heavy duty spray) would work?

Does anyone know if the tubing used in the banshee bungees is solid or hollow? and roughly how thick is it?

Sorry guys, been a while. The banshee bungee tubing is hollow but you have to understand the rubber is vulcanized, some process were they add sulfur to the rubber. Will post pics of the build soon.
