I’ve never used a Hawaiian sling before (a spearfishing tool), and thought I’d make one for the next coast trip. It’s made of PVC piping 15mm and 3/8″ surgical tubing. The shafts are 5mm x 900mm high carbon steel with a notch cut into the back like an arrow.
I used zip ties to hold everything together, we’ll see how long they last in the salt water. Make sure you glue the PVC pipe well together!
Similar to a slingshot, it has a wrist support to counteract the force of the band pull.
I welded on a smaller gauge wire for the barb, and grinded it smooth.
An “arrow” string for notching.
Ready to shoot!
Inspired by a great snorkeling trip to Jervis Bay, I’ve made a couple pole spears similar to the ones we used to make in California. These are pole spears for spearfishing shallows and sandy reefs.
I was able to find the same green garden poles a the local Bunnings, a nice cheap steel tube wrapped in plastic. They even have little bumps for added grip. Although not the strongest material, it is lightweight, and makes for a very balanced and fast shot. Hit a rock and you may bend the tubing!
We also used bamboo which had the same lightweight characteristics but was a little more resilient to missed shots into the reef. It does split however with time and (ab) use.
5-prong spearhead reused from the old polespear I didn’t like.
Sling band made from nylon rope and 3/8″ surgical tubing from Clark’s Rubber.
