I began by cutting the port door jamb that I'd epoxied together earlier down to size. I test fit it, and then drilled mounting holes, countersinking each one, on both door jambs. After wiping both mounting surfaces and the edges of the plywood bulkheads with acetone, I mixed a batch of thickened epoxy, coated the bulkhead edges, and screwed the door jambs in place. The tops of the jambs will be trimmed later to accommodate the head of the doorframe that follows the curvature of the cabin.
I cut the port door jamb such that the epoxied joint would be at the bottom and out of sight.
With a little time remaining, I decided to install four cleats for the port head locker. That done, I cut a new shelf out of 1/2" ply and set it in place. Ultimately it will be glassed to the hull and chainplate.
And that was it for today.
