Making a home made paracord* bungee** to take my new and very small Gerber Dime® multi tool on any epic adventures I may set off on turned out to be pretty worth while. Claiming that it will outlast the polar caps probably isn't saying that much.
I wanted to make it so I could use my new little multi tool while it was still attached to my belt so I couldn't lose it overboard, but didn't want it dangling around my ankles when I let it go without re-clipping it. I figured if I wasn't actively using it, I'd clip it to my belt, but when I was using it, I could just it to still be attached. That would mean there was a loop of rope hanging down a foot or so from my belt, and I thought that might be annoying. I have a bungee cord with a hook at each end thats been sitting in water outside in the sun for 3 years and is still in perfect condition, but I have also bought a few dozen that didn't make it 3 months. I have no idea what brand the good one is, but even if I did, it's too think for my requirements.
The invention engine said I should make my own.
The mess should look something like this when complete.
I cut a length around 30cm long, and around 2mm wide
Try to avoid any nicks and rough edges as this is where it will break if stretched too far.
But we wont be stretching our too far so it wont matter.
I attached to other end of the wire to my house because it was the only heavy thing I could find.
With the help of some pliers to grip the paracord, it was simple to pull the strip of inner tube back through the empty paracord.
As it is in this pic, I can stretch it to around twice the relaxed length.
So now I can get a stretch of around 3 times the relaxed length.
To get maximum stretch, bunch up the paracord until it's still slack when you stretch it. This means the inner tube is the limiting factor. Then let a little paracord slip through your fingers until the inner tube is still fully stretched, but the paracord is also tight.
Tie it off, and you should be set. As long as you didn't stretch the inner tube too much before tying it off, the paracord should take any extreme force that's applied, and your rubber inner should stay intact for the next 25,000 years or so.
All in all this suggestion from the invention engine turned out well.
The short length of very thin and super strong DIY paracord bungee is ideal to suspend my new favorite tool.
