Three more hours of work during these holidays: still beveling the akas... Not much to show here other than a lot of wood shavings. I do the rough part with the power planer and Cinzia does the refining work. There are 8 substantial wood planks to fair...

Akas (5)
Two more hours of work yesterday, continuing to shape those akas which are taking more time than expected.
At a certain point though Cinzia's mom gave us a bag of freshly made "pettole", which are a typical Christmas food in southern Italy. Delicious!
Merry Christmas!

Akas (4)
Two hours of work yesterday during which we started to bevel the esposed edges of the aka planks.
Here's how we're doing it, using the power plane first, cutting a 45° bevel
and then finishing with power planer, rasp, Surforms and sandpaper

Akas (3)
Four more hours during the week end. Yesteday we drilled all holes for the swing-wing aka structure which seems to work properly.

Akas (2)
Six hours of work between yesterday and today. We completed the initial akas installation, making sure they're as square as possible to the centerline as well as parallel as possible to each other. It takes a certain number of measurements, tiny adjustements, "splitting the difference", and so on. At the end, the installation looks accurate to +/- 5 mm (about 1/4 inch).
At the end, we drilled all necessary holes with a 10 mm bit and made sure that the swing arms do swing. This is a video but it does not play in my browser...
This is a front view of the forward ama with the swing arms installed, which gives an idea of the size of the boat. The aka "doubler" is not yet glued on. Those akas are HEAVY. We'll see how they behave at sea.
It's getting colder now so after the sunset we went inside to fiberglass one side of the false transom with two layers af 160 g/sq.m. cloth and epoxy.

Akas! (1)
Two hours today in which we started working on the akas. First thing was drilling the holes in the mounting blocks. We used a 10 mm bit, and a drill support the keep the hole vertical. No big deal really. We then drew the centerline on the forward aka, centered it on the blocks, aligned it square with respect to the centerline, and pinned the position of the bolt hole from underneath trough the bolt hole just drilled int he mounting block.
