The actual act of rivetting into carbon is the same as riveting into aluminium... it's just more critical exactly how you do it.
I agree with Rick that you should try and get hold of some of the carbon rivets as they don't squash the fibres like a normal rivet and so you won't cause a structural problem in the mast. If you ring me at work tomorrow I can probably get you a couple in the post if we have any in stock. |

Surley it should be exactly the same?
Drill out old rivet Slop on some of the anti-corrosion gloop Put Rivet into Rivetgun Insert into existing hole in mast, ensuring gloop spreads over it Pull handle a few times, until a loud *BANG* is heard Done! Now turn around, and try it on your own boat! Good Luck!! |

Salt water does make things worse as the salt in the water acts as an electrolyte and that helps the galvanic corrosion. Pure water is a relatively poor conductor although throwing a toaster in the bath is still a bad idea. Use dichromate paste in any case - it saves having to replace every rivet if you move to the seaside. Also, with Tewksbury's sewage treatment plant getting flooded the other week ( I used to row at Lower Lode, below the weir as a nipper so I know the area) I'm sure there were lots of electrolyes around Forget lazy tongues, get an air gun! |

It only reacts in salt water doesnt it??? i thought that the salt water, carbon and alloy created a kind of battery, as for rivet gun get some lazy tongs!

And a tough rivet gun! You'll need more muscle power for that than driving a rivet into aluminium.
