How to make gun bungees?

[Chi]

Does anyone have a step by step instruction on how to make gun bungees?

 

[deep thinker]

Step 1: Get in car or on bicycle
Step 2: Go to closest spearo shop
Step 3: Ask for bungee
Step 4: Take out wallet and pay
Optional Step 1: log onto internet
Step 2: go to RA or similar site
Step 3: Place order
Step 4: Pay by credit card rofl

Seriously though, ours are made with hollow bungee cord with a lenth strong cord inside (for the life of me cant remember the name now :duh), you could also possibly use surgical tubing, the kind that stretches. The cord needs to be longer than the bungee, these get tied off with a tuna clip that gets attached to the shooting line and a loop on the other that connect to the gun using a constrictor knot on the outside of the bungee between two knots in the inside rope with the bungee bein folded over the knot to hide it.
Makes sense yes? :friday

For our smaller fish, I wonder if anybody has come up with anything lighter/simpler. I know Omer sell these:

Omer Bungee [Omer Bungee] - $0.00 : The Freediving Store, The one stop shop for all you freediving needs.

By the way, how do you tie/clip/swage/crimp the ends of these to your gun & line? Nylon blind cord to the muzzle tip & crimped loop of spearline to the other end?

But an image posted my Foxfish last year made me wonder if some folk just use thin bungee cord (sold in dive shops)?

I'm not a big fan of the coil over type myself. I like the type TechnoSport distributes (they make them inhouse). It's like tuna cord or something. A loop is tied in one end. Then rubber, similar to waht you would use ont a polespear over the cord. Tie on a big snap swivel on the other end of the cord. Pull the rubber over the barrel of the snap swivel and over the knot in the loop end. Then a steel ring crimped over the rubber to keep the knots from coming out.

If you can find them locally, the snap swivels will run $5 or so and then the cord and rubber are minor. For the price, just order a couple online or buy at your local shop. No one has the snap swivels that big around where I live, so rather that buy all the components, I just order it and I'm done.

This is what mine look like as described in that thread. Simple and effective. You can make the stiffer/softer simply by using thicker/thinner bungie cord.

X, the picture you posted is of the bungee I was talking about. You feed the line through one hole, then "coil" or wrap the line around the bungee then through the other hole, then tie on you snap hook.
I said coil over because it reminds me of a coil over shock on a mountain bike, motorcycle or car.

Thanks Chris. I wasn't sure if the omer bungee (or regular bungee with a woven nylon cover) might be strong enough alone but it looks like folk don't rely on it.
