| Hi i have a brother in law who makes carbon fibre rifle stocks and asked me if i wanted him to try make me a carbon fibre speargun. Would this be worth it? Could it be done? Cheers |

yup it can be done but you need to use proper marine carbon fiber so it doesnt get water logged also try get it filled with that expanding foam for more bouyancy and ridgity ------------- enjoy today tommoro could be even worse |

| Some amazing guns have been built using carbon fibre. I like the Aimrite guns. There are a few yanks that do some amazing builds as well. Check the spear board forum as there's some good threads there on car on made guns. |

| C4 really needs to hire an english speaker to edit their website. The euro mega-carbons have the unfortunate flaw of being an overgrown euro gun. You can put mud tires on a Ferrari, but it's still best left out of the swamp. |

"marine" carbon fibre? It's carbon drawn to a fibre and spun, carbon fibre is carbon fibre? Carbon fibre doesn't get waterlogged if it's resined correctly |

Their translations are hilarious and poetic though. I say leave them as-is! http://www.nautilusspearfishing.com/products-page/bleu-tec/ - http://www.nautilusspearfishing.com/products-page/bleu-tec/
The big advantage of the Euro style is that the handle is almost in-line with the spear. That means recoil is pushing almost straight back, rather than pushing up the muzzle as with the US style mid-handles.

Perhaps some resins used with CF are water-permeable?
Expanding foam for buoyancy is pretty hard case.
Chris, I remember some of Tom Sietas's translations being pretty hard case. "I made attack to the pond with my monofloppy."

| C4 Carbon guns are dogs - heavy as. They look great on the wall though. |

| C4 is an Italian brand - they make guns that are beautiful, over-engineered and weirdly dysfunctional. The trigger contains about a million moving parts and is made of titanium, but there's nowhere at the front of the gun to hold a shooting line. Presumably when you're designing such a masterpiece, mundane practical elements like attaching the gun to the spear it shoots are beneath consideration; an insult to the maker's art. |

Does it have to be a euro style gun or were you thinking about a rail gun? |

| Wasnt thinking style at all, but yeah could a copy of my rob allen rail gun be made in carbon? |

You use epoxy with carbon, reckon he's got confused with S/steel needing to be marine grade Custom carbon gun would be nice! My next woody will have 2 or 3 carbon stringers to add stiffness and slimm down the barrel, but a full carbon would be cracking. Are you going with a simple tube gun or making something special? |

| Really open at the moment, he just raised the idea to me. So said i would do some investigation and come back to him. Not sure what is the best option, maybe try something simple first like a tube? If i can find a great plan/blue print then will run with that probably |

The internet needs a sarcasm font, as sometimes, I honestly can't tell. Anyway - CBS: you can buy a length of carbon 'round tube' relatively cheaply (I am not certain where from but friends have done it). I think guys adhere a plastic 'rail' to the carbon tube and then add readily available aftermarket muzzles, handles, trigger mechanisms, rubbers, shafts, string lines etc to make 'custome' guns. I fabricate the odd small thing and it takes aaaaaaaages and usually comes out moderately crap. It is partly because I don't know what I am doing, but mainly because the people that make things for a living find economies of scale and were able to do more field testing than me. Their boring, off the shelf products are better than my intricate and unreliable home made ones. Getting your mate to assist in the creation of a carbon gun could be mega fun, but in time and materials it will cost triple what you could buy a better gun for. That doesn't mean it is a bad idea, it just means it isn't an economic idea. MTCW............... but I think the local timber gun builders would agree that they aren't in it to save money. If you do this then take lots of photos and we can all share in a winter project/ Lord knows it is horrid weather on the south coast right now.

Get him to make you some carbon fins, I kept wanting to try that as i spent hours making composite parts for my summer work... I reckon some laid up so they are wavy like my stingrays would have looked pretty mean...

RA has already made one that works: http://www.wildblue.co.nz/products/index_dynamic/product/5795 - http://www.wildblue.co.nz/products/index_dynamic/product/5795 UJ pretty much hit the nail on the head.

I have the above ^ gun, and I think it's one of the best guns I've ever used. I brought the 130 for a kingy gun but realized its manoeuvrable to use for almost anything.

| What UJ said- Call Killwell in Rotorua, they are super helpfull, got 2x 120 barrels for under $100, choose a nice handle, I used Rabitech and Oceanhunter has some rails that already have double sided tape on them. CF is such an easy and under rated material to work with. just my 2c |

yeah but it would be quicker to make one than order one
