Once the plywood reinforcement was epoxied into place, I added a layer of fiberglass mat over the ply and overlapped it onto the surrounding fiberglass. Now the mounting points are integral with the body and will provide a strong mount for the framework.
First pic shows the ply in the horn area after the fiberglass was applied.
Second picture shows the overall layout of the reinforcing points and the plywood installed.
Last picture shows the 'glass mat cut to size and ready for resin.
