Hello Cliff, I recently read your article and I am installing my chain plates port side this weekend.I just have one question. How did you apply the epoxy to the fiberglass strands? Did you wet them down first on a table on plastic ( like the Mack Sails YouTube video) then bring them in and install them? Or did you brush them in directly once the plate was inside the boat? Also did you use a brush or a roller to apply the epoxy to the hull? Any information you could provide would be greatly appreciated.
The way I installed mine is as follows:
First, I had mine made individually, so if yours are made as a one unit it may be harder.
I had a helper for this part of the install.
I soaked the part of the strands that wrapped around the chainplates, and had a bit of epoxy microball mix paste on the top of the angle piece where it butts up to the deck. Then I took it and pushed it through the deck where my helper attached the stay to it, he tightened the stay up to put some tension on the chainplate. Then I wetted down the strains with the epoxy. I did this in August in FL so it was very hot... if I remember right, I had over an hour work time ... you should have more with the cooler temps if you are using the slow cure, which was recommended by a fiberglass guy I know.

Having replaced midship plates with new factory one piece units,I soaked the central part of the fibers then brushed in the rest much as the factory did it. I replaced the aft plates sandwiching them with reinforceing the the glass and thru bolts. If I had it to do again, I would do the midship plates the same way, orienting them to the load and upping the gauge of the straps. The aft chain plates are also begging for a change., trust me on this . Change them out.
WARNING, WARNING, don't forget the Bob stay chain plates.. Thru hull plate and the one bolted under the sprit. And the bolts, they are tired to.Just because you can't see most of it,doesn't mean they are not planing to get you. Plenty of stress ther . I have photos of them, Caution, some sailors may find them upsetting. I changed it out while still in the water. Doable if you don't mind getting wet.with a new bobstay, still available from the rigging shop next door to the old IP factory.

Does the same apply to IP27's?
Also, there should be some sort of strength test devised to inspect them for fatigue if it can't be done visually... Dishing $10K into a boat that is potentially perfectly fine is a big waste in my opinion...
