Following a discussion in this forum few months ago, I have now done most of the recommendations provided by Lars. It was not an easy or quick job. The job also necessitated real heavy duty tools. Summarizing the whole thing:
- The nuts were removed
- Washers were added. Size and thickness varied due to the length of the bolts. In general, we aimed at 12mm thickness but in some places we had to go down to 8mm.
-The Mast step was thoroughly cleaned and treated with protective paints.
Attached to pics. (there is some more cleaning to be done)
