We are starting the fun portion of the project now that the old roof has been replaced with a new 1" thick roof.

Pic 1. Laminating the edging for the roof at the front curved corners. I'm using 6 layers of 1/8" Okoume marine plywood. The factory curves were saw cut from a single piece of wood.

Pic 2. Due to the expansion/contraction, water incursion and age, the corners started to crack around 10 years ago. I patched them every year and they would crack in a different place.

Pic 3. 6 layers of 1/8" Okume marine plywood laminated in a single clamp up. Using System Three Gel Magic adhesive which is a huge timesaver. Instead of mixing epoxy and various fillers to make adhesive, Gel Magic is a two part adhesive that doesn't sag.

3. After the corners cure, they will be trimmed and shaped prior to the installation of the rest of the edging. Almost didn't have enough small clamps. Could not use the larger clamps because the weight of the large clamps distorted the curve.
