He then went up the mast to begin an assessment of the rest of the rigging and to my relief he pronounced it all OK. I told him that I was worried about the rust that was appearing where the wires meet the swages, which opened up a good explanation of why it isn't rust but rather staining from all of the airborne material that works its way down the wires over time. I asked him about the American practice of putting silicone sealant at the swages, which is not recommended by the big companies probably to avoid liability issues. He suggested that a lanolin grease would be safe to use, so I plan to treat all of the boundaries between wire and lower swages with "Lanocote" lanolin grease.
Section of Dyform wire |
I am including a photo of a section of the Dyform wire of the new lower shrouds. Note the smaller wires between the larger wires. The outer surfaces have been flattened slightly. The effect is a stiffness half way between ordinary wire and rod, with the interior so tightly compressed that it is unlikely that any moisture or material will pass through it.
