Ama bulkheads

Four hours of work today. We prepared the bulkheads and transoms for the amas. The ama bulkheads are somehow more elaborated because each of those supports one of the 12 mm bolts which connect the amas to the akas. The bolts are epoxy bonded to a substantial wooden frame (total thickness of 6 cm) screwed and epoxied to the bulkhead.

The 12 mm DIA steel bolts are epoxied in 15 mm dia holes in the frames. Here I am drilling one of such holes.

At the end of the day we discovered, to our dismay, that those holes should have been drilled on the half-assembled amas using a template to make sure that the distance is exactly 88 inches. However, the drawings also report the exact distance between the center of the bolt and the bulkhead face! Well, we'll see how it goes while assembling the ama hulls. If the bolts turn out to be at the wrong distance, we will fill them and redrill new ones.

And here is the completed work


Total work time to date: 107 hours
