: We will use that track to install a storm trysail track on the mast. The same stainless rivets we bought for our railings will work on that, as well. I hope that you're not planning on using stainless rivets on an aluminum mast/boom! You're looking at serious corrosion problems if you do that. -- Geoff www.GeoffSchultz.org |

I've also heard of using various coatings, like silicone caulk and loctite, to try to reduce the galvanic action. What do you recommend in lieu of stainless fasteners? |

Aluminum ivets shouldn't be hard to find... one example.. http://www.rivetsinstock.com/rivet71.htm or.. http://www.aluminumrivet.com/ |

Since the corrosion takes place primarily the aluminum side of the joint using aluminum rivets will result in rapid loss of the rivets.

Bruce-in-Bangkok (Note:remove underscores from address for reply) I recently removed the upper shroud attachment SS plates from a 30 yr old aluminum mast. The rivets were aluminum. The aluminum mast portion under the SS plates was badly corroded away but the rivet heads were still in good shape! There was a large stainless bolt going all the way through both attachments and the mast and this is what was holding everything together. Gordon |

I've got miles (or so it seems) of black anodized AL Harken track on my boat. IMO, _the_ "right" way to attach anything to an AL mast is to drill and tap the mast for ss fasteners and then isolate _all_ of the parts with Durlac (or similar). BTW, I'd be very grateful if anyone could point me to a source for Durlac here in the States. It seems silly to ship a tube up for New Zealand. Merry Christmas! -- Tom. |
