Re: Whisker Poles needing work
I did this last year after noticing a few damaged rivets. I used these Aluminum Blind Rivets with Aluminum Mandrel
Domed Head, 3/16" Diameter, for 0.751"-0.875" Material Thickness from McMaster-Carr: https://www.mcmaster.com/97447A071/
You are riveting three pieces together so you need a rivet with at least 20mm grip length. I now inspect the rivets on the poles as part of my pre-departure checklist and so far they are doing fine.
Here's some pics of the worst rivet and the three pieces that make up the assembly:
Some of the holes were a bit "ovalized" which is not ideal for a rivet joint, but we've but sailed several thousand miles using the poles since I did the repair and they seem to be fine. If I notice any issues over time, I will likely just drill four (4) new holes and rivet the new holes.
