Chain Plate Question

Just did a dye test on my chain plates and I need to replace some of them. As usual there are no standard sized ones that will fit so I need to have them custom made. I'm thinking of making them myself - depends on time and what I get for a quote from some local people.

My questions is this- at the top of the original plate they welded a large washers on either side of the plate- I'm guessing to give the pin more surface area to hold onto. Do you think it's necessary to have those washers? or can I go with just the straight bar.

The plates are 15" long, 1 1/8" wide, 1/4" thick with a 1/2" overall bend. Attached to the inside of the hull and through bolted with 5 bolts.
thanks

Re: Chain plate Question

1/4" thickness does sound a bit thin. I think your idea that the washers are there to provide a larger bearing area for the pin sounds right.

I would consider just making the new chainplates out of thicker material. Mine are basically the same shape and similar size so I just ordered some stainless bar stock online to make the replacements. Thought about cutting and drilling myself but was pretty cheap to get it done at the local machine shop.

Re: Chain plate Question

I agree. They will look more elegant if made from one thicker piece of stock and will have reduced chance of crevice corrosion.

Are think chainplates some sort of "smart-plates"? Do they interface to NMEA2000 and my chartplotter?

Re: Chain plate Question

Go full thickness. Greater strength; no crevises; no heat history. Use 316L material or go for Titanium Grade 5. Check out my photos for the project on our boat. Four plates 1/2 X 24 long X 2-1/2 wide. Good catch finding the damage before the disaster. Ours was detected when I removed & polished the old ones.
