All About Pole Spears & Slings What is it about that traditional method of the early hunter/gatherers under the water? These devices are indeed interesting and effective.

Pole spear build

Ok so I've decided that I'm gonna give it a shot and build my own pole spear. There is a few things I am trying to figure out still ( 3 pcs 8' aluminum general use spear)
6061 t6 aluminum alloy 3/4" ( thick walled tube or solid rod)
316 stainless steel connection/fittings ( any help with thread would help)
band ( clueless. What is the best band available )
tip ( I would like to have multiple tips so maybe headhunter or crist what thread do I need )
any ideas or suggestions are welcome
Thanks in advance hope to post pics soon

Re: Pole spear build

Once you decide on your raw stock in tubing. You can look at ID size and that will lead you to a thread size. If you go too big, then you will not have much wall thickness post threading operation.

You have choice using a cut thread tap or a form threading tap. Different hole requirements for each type. Pay attention to what class of threads you are looking for.

If you don't have taps and dies, you can always single point the threads. Lots of options.

So many don't understand what a thread pitch is, and not even going to thread classes. So many call an 8mm thread , a 5/16" thread, some sellers of spear-o products say they are close enough to work.

If you had an arbor press you could also press your fittings into the Tubing. Press fit tolerances , you can look that up.

If you decide on solid round bar stock, you could just cut the threads into the stock.

Pros and Cons to each design decision.

Good luck with the build. Get a hold of Aaron Crist if you want rubbers, he can set you up.

Re: Pole spear build

I built a pole spear out of an old ski pole, another length of 3/4" aluminum tube, and fabbed my own flopper tip on a 1/4" stainless tip. If I could remember where the heck it is I'd take some pics.
