9/32 or 5/16 Shaft?
Hey. I just wanted to know what peoples shaft diameter preference is and why? Especially for such fish as halibut,yellows, and wsb. I prefer a 5/16 myself because it seems to be stronger and hold the fish on a little better. What do you guys like? Thanks.

9/32 for Halibut and 5/16ths for WSB and YT.

Re: 9/32 or 5/16 Shaft?
I suppose that if you have a heavy enough gun to limit recoil and thick bands to launch it, a 5/16" shaft has more range and hitting power. But I have taken the majority of my white sea bass and yellowtail with a 9/32" shaft and have never bent one in a fish.
I think that a lot of people make the mistake of using a 5/16" shaft in a gun that is not built for it. The slip tip or flopper is what holds a fish, and the shaft thickenss has nothing to do with it after it pushes the tip through the fish. |

Re: 9/32 or 5/16 Shaft?
Does anyone know which, if any, of the speargun makers are using the new 2101 stainless for their shafts? This stuff is looking like it's hot sh!t, and could make awesome shafts.
From the specs I've reviewed, it has the same corrosion resistance as high-end 316L stainless, but has twice! the strength (tensile and shear). Apparently, while it's still a duplex alloy stainless, it should be priced comparably to current stainless alloys. It's considered a "lean" duplex, because of low Ni and Mb percentages. That's what keeps the price down, too. Seacidal

Re: 9/32 or 5/16 Shaft?
Man, I shot blue perch and sergo all the time with my 5/16 in shaft. Sometime the fish fight so hard they drag me down to the bottom and pull themself off my shaft. LOL..

Re: 9/32 or 5/16 Shaft?
9/32 Yellows get close and whites are soft meat. I have yet to not penetrate a fish with a 9/32 (I've missed plenty). 9/32 seems to really minimize recoil and allows me to weight my gun without having to add wood.

As I said previously, I think that some people use 5/16" shafts in guns that can't handle it, with a cost paid in reduced accuracy. But of course if a gun is heavy enough and has enough power to launch a 5/16" shaft accurately at the same speed that another gun launches a 9/32" shaft, then there is no doubt that the 5/16" will have more kinetic energy. |

Re: 9/32 or 5/16 Shaft?
Bill,
You're quite correct. I didn't mean to imply that you can't stone a fish with a thinner shaft. It certainly can, and is, done. And you're also right that the shaft needs to be matched to the gun. However, I think you'll agree with me that, for large fish (like big sea bass) there is an advantage to be had by using a shaft with more mass. Recently, while filleting a sea bass, I was showing my wife the location where my spear shattered and passed through the fish's spine, I noted that the vertabrae were about as thick as my wrist (approx. 1 1/2"). Even with a 5/16" shaft, my shot was able to put only 3/4 of the shaft through the fish. While I might not always need it, I don't mind carrying the bigger shaft. I figure it makes it that much less likely that I'll bend a shaft or tweak a tip. (although, if the new stainless alloy does what it claims, I might be inclined to change my mind.) Seacidal

You have really piqued my interest in this new shaft material. |

Re: 9/32 or 5/16 Shaft?
Like Bill, I just don't see enough of these fish. If I was seeing large enough fish that the 9/32 wasn't penetrating I'd be the first guy to buy a 3/8 cannon.

Castor,
I think we need to move to Ventura. |

Re: 9/32 or 5/16 Shaft?
Chip,
Now I understand all your success. When you used to dive with me, you weren't that good, so I was wondering how it was that you came up with all these big fish now. Its diving those Majorly Productive Areas that explains it. |
