I think that reality is that we each must judge the situation. I agree with Monster that it should not be taken lightly. I deleted my post/video for that reason.

woah!

i feel so sad every time a fellow diver pass away...RIP brother..

John, give me a call. I have a couple that might work for you.

Also not quite what you asked for, but another option if you want a 5/16" shaft instead of 9/32" . . .

I could take a standard stainless shaft, and re-cut the notch to a euro configuration. It would shorten the back (move the fins rearward) by about 5/8".

I could do the same on a spring steel shaft, but then you wouldn't have the coating to prevent rust.

Robert, I know that fishing in the marine reserves is forbidden, there are still many places to fish and I understand your point that we need to get strong or they (DRNA) will continue to create more reserves and every time we’ll have less fishing areas for ALL of us.

I’m not fighting against recreational fishers, because I enjoy what I do, regardless if I’m leaving from this now, it’s not about that….“commercial or recreational”, I do go out and fish with recreational fishers, and as friends we share expenses, like gas, food, ice, etc…I don’t think this is chartering, I don’t need permits to go out with friends and split expenses in equal parts FOR ALL, you can ask the people that fish with me from this an other forums from different place in the world, if I’ve charge them for something or we share everything like a group of friends. I DON’T make any monetary profits out of this. For me it will be the same as if I go my self, but we rather do it in groups….good company of friends.

core sub there are some videos here in the forum...

I hope all parties understand that there are those who hate spearfishing. They do not care whether or not we do it for sport or to pay our bills. Name calling, dragging each other through the mud, showing our asses, etc. only serves to further their desire to shut down what we do.

The resources of the ocean are not endless, and must be managed. We can either be a constructive part of that management showing that we can be selective and responsible in our take, or we can fight among ourselves and let those who hate our fishing method make the rules.

Dan,

The difference between a commercial fishermen with a spear gun and a recreational is that the commercial is permitted to use scuba tanks and don’t have bag limit in his captures, otherwise the recreational only can fish free dive and the DRNA is trying to put on a bag limit in some species. For that reason a lot of people are complaining and all of us that spear fish have the same restrictions that are in the article 8 section 5, that forbid us from spear fishing in decks, lakes, rivers, estuaries, reserved areas for bathers, marine reserves and at night, in section 6 forbid us to fish less than 100 ft from the shore.

Those are the only two things that affect the recreational fishers or commercials that spear fish. Now you tell me why they don’t agree?

i lost count on how many i have kill...........

Thanks for all your efforts Roberto. Please keep it up. Let us know if there's anything that you need.

Chad

Asesino im with you in every single word..........:).....

im in for the ponce meetin....im going with bolo prix....roberto if you can pm me i would apreciate it..just tell me how to behave with those people...and how to react with them...

woah don! thats a big mahi...thanx for sharing...

very nice post...looking forward to build one...

thanx for sharing the squids video.....here in pr they grow like 10 inches...for me those r some big squids you caught there...tan bueno q sabe el arroz con calamar co-oo!!......please keep the pics and videos coming...:)

correct me if im wrong - my view of it is that the aluminum is not the weakpoint but a slip-fit joint is, by welding it together doesnt that make the aluminum weaker but the joint stronger???

A tight fitting joint can be an incredibly strong assembly, because it avoids all the extra unknowns that a weld brings. Changes in the crystal structure (embrittlement), annealing (softening) at the heat affected zone, stress concentrations where the weld bead stops, and on and on. Obviously, welding is done every second of every day around the world. But lots of times, a good mechanical joint is actually better.

In your case, the weld will be plenty strong, and the addition of the extra filler metal will compensate for the reduced strength due to losing the heat treatment on the aluminum. But where your weld stops, right at the "toe" is where the problem will arise. At that point, you no longer have the reinforcement from the weld bead, but you still applied enough heat to anneal the rod.

I checked out that shapelock stuff, it could be a very viable solution especially since the spear is stepped and would further reduce the chances of it sliding. please enlighten me about making it more grippy(first thought that came to mind was to use something textured to mold it)

A textured glove, or a thread bare cloth will work. You can also press it into coarse rock salt. When the Shapelock is hardened, run it under warm water to disolve the salt, and leave a coarse textured surface.

Quote from mrmike

If you are using any of the 6000 series aluminum alloys, you really don't want that weld that you show running all the way around the 1/2" rod in the second option. It's not about the quality of the welder. It's simply that the heat will further weaken (anneal) what is already the weak link. The weak spot isn't where the weld IS. The weak spot is the edge of the Heat Affected Zone, where the heat of welding has softened the base metal of the 1/2" rod, but there is no additional filler metal to provide reinforcement.

Maybe I'm over thinking it. I tend to do that. I get really mad at myself when something breaks because I overlooked a design flaw.

Anyway, you can get the shapelock plastic at www.shapelock.com. When cooled, it is about as hard as UHMW. There are also a couple of ways to make the surface more "grippy" if you go that route.

Just curious, but why are you welding the rod in place instead of just securing it with a simple pin? I could understand if the fitup was poor, but since you have gone through the trouble to accurately ream the tube ID, it should be a nice fit. Probably good enough that a little silicone or locktite during assembly would easily waterproof the joint.

You probably already knew this, but most aluminum rod and tube extrusions are alloy 6061 or 6063. Both get some of their higher strength from heat treating, and will soften considerably when you weld them.

Also, I was wondering about your idea of forming a grip around the smaller rod. Would a formed shapelock grip make it easier to hold?

those r some big squids!!
