On close inspection, I discovered a interesting wear line on one of the rudder pins. The three pins are not in perfect alignment. Here we see that the pin-receiving hole would want to go more towars the boat. I think the easiest fix is to enalrge the receiving hole. Also, the receiving hole had no wear on it at all. This means that the pin is of a different hardness. This can perhaps be attributed to welding temper: the pin is TIG welded to the sheet metal seen on the picture, right at the junction of the sheet and pin. This place is softer due to weld heat and would thus yield to the same but untreated steel. Or should the weld be harder than the base metal? I don’t know. Just my thoughts.
