chain plates

[david clack]

I have a small clinker traditional canoe sterned yacht. I notice that there is slight movement in one of the chain plates. I plan to take it of and rebed and refasten it.
The chain plate is bronze. My question is what is the best metal for the fastenings, bronze or stainless steel. It looks as is the old fastenings are steel, there has been some slight rusting.
I plan to rebeb with Sikaflex.
Any avice gratefully received.

Bronze. Why is there motion? Are the steel fasteners rusted and the fasteners loose in the chainplate? Are the fasteners broken?
Is there a problem with the timbers to which it is fastened?

I would recommend a switch to bronze fasteners as well. Is this movement a lateral one along the direction of the load, or a pivoting one caused by an unfair lead. It might be a problem of wood fibers crushing. A really good chainplate would have a " matching" bronze backing plate to spread the compression load, not just small washers. Might be time to add one if missing. Are the holes in the planks elongating.Here's a spot where over boring existing holes, filling with epoxy/ glass fiber putty, and reboring to snug size would be well worth the small project time and expense. You don't want to neglect water damage to these planks.
