Dorade Boxes | Trimming Top Edges

When I fitted the Dorade boxes it was obvious that the sides were slightly oversize and would need to be trimmed.

I laid the long level across the bulkheads to see where the cabin roof would meet the Dorade box sides, like this.

I marked in the line where roof and box sides meet, as here in the port box.

Lastly I removed the excess material with a sharp Japanese saw and cleaned up the edges, ready to install cleats where the roof will land.
