davec 0 Posted June 30, 2015 Share Posted June 30, 2015 I have an exit block that I want to attach to the mast on a Starling. What sort of rivets should I use and where is a good source in NZ? Thanks Quote Link to post Share on other sites
Island Time 893 Posted June 30, 2015 Share Posted June 30, 2015 The strongest rivets (also the most expensive!!) are monel. Any of the fastner places have them. Quote Link to post Share on other sites

John B 93 Posted July 3, 2015 Share Posted July 3, 2015 Aluminium bolts ? seriously ? Ullrich have monel rivets in a few sizes , be prepared to be shocked at the price per unit , but of course its cheap insurance. You can make washers to isolate the SS from the ali out of ice cream containers or even use tap washers if you have the room. Quote Link to post Share on other sites

You can make washers to isolate the SS from the ali out of ice cream containers or even use tap washers if you have the room. I'm new to this game but knew about electrolysis problem. Task was to attach plastic tube rub rail all around the gunnels of my aluminium dinghy to stop it scratching the big boat. In the end I used SS self-tapping screws. I thought of rivets but didn't know how to use them with washers or whatever to avoid squashing the plastic tubing too much. Keen to know what I could have done.

KM... 954 Posted July 3, 2015 Share Posted July 3, 2015 Use Monel rivets, it's a more inert metal. If you want rivets to pull not as much as they can you can make a small groove in the nail (the bit that runs through the rivet) with a small file or similar. That will weaken it so it wont pull in as hard. You can push the nail out, groove it then put it back in.... unless it's a blind rivet of course. Some experimenting wit the groove size maybe required if you want to be more specific with the resulting loads. Quote Link to post Share on other sites
