Here's my latest attempt to bring back life into a worn Imp door latch plate. The hard steel star-wheel on the door wears away the soft potmetal of the door latch plate. Over time grooves wear into the latch and make it impossible to latch the door without slamming it.
The first move is to put some washers behind it and move the contact point. When this fails and the grooves just wear wider, then another solution is needed.
I then took and cleaned up the teeth of the latch plate, and even roughed them up. This way the epoxy will stick better. I coated the teeth with two-part epoxy and then fitted a thin stainless steel sheetmetal piece over top of the original potmetal. This should prevent wear since the potmetal is protected and the stainless is a bit more resilient. We'll see how it works.
