Spring is here and I finally removed the chain plate and ground down the rotten and cracked surface.
The plan is build it up with resin and fiberglass. Drill over sized holes and fill them with resin. I have a stainless steel backing plate made and a friend suggested making a stainless steel top plate too. Makes sense to me so I will take some measurements and visit the local http://www.metalsupermarkets.com/. No order is too small for these people. The bow is now sealed with plastic and duct tape. I will open it up every evening this week and remove the moisture. It should be totally dried out by next Saturday when I apply the resin, weather permitting.
