....and replacing it with stuff that doesn't work  Nitromors and Creasote went the same way. All for the greater good I suppose.
To be fair Chromate has been known as a carcinogen for years. Wear Gloves.

The best rivets for high load fittings are monobolt rivets.
The important parameter is the sheer strength of the rivet. Monel rivets are good allrounders on smaller rigs/boats. Most important is the preparation of the hole. Use good quality of drill bits, deburr the holes (you can get a special tool for inside the hole) Make sure the fitting fits snug to its mating surface, any gap will significantly reduce the strength. Fettle or form it if required. Make sure any necessary alignment is considered. Particularly spreader brackets with the mast heel. Obviously make sure the rivet is the correct length,- grip range Use a good quality riveting tool with the correct nozzle The jointing compound has been covered, and most masts are 7000 series alloy which has good corrosion resistance (relatively), but if you have any other alloy it may require a different type of insulating material/compound. |
