Deck seats (2)

Spring is coming in at last, so it's becoming more pleasant to work in the garage. We worked 2 hours this morning to cut out all the pieces to build the two deck seats, which are 2 meters long and 75 cm wide each.
Here's a view of the to panels of 12 mm thick plywood cut to size after being stacked


and here's yours truly relaxing to give you an idea of the size of the seats


We also cut all the longitudinal beams that will be glued to those panels next time.

Deck seats (1)

During the week we spent two more hours to complete the coating of the aka bolt holes with silica thickened resin. This morning we worked two hours: we took the vaka outside to check again the aka system and to take measurements to cut the two panels of 12 mm plywood for the deck seats. Those will be 199 cm long and 75 cm wide.
Here's a view of the two akas with the doubler

Akas (bolt holes)

The thing went so and so since we used an excessively thick putty (resin + silica) which could not flow freely in the space between the bolts and the oversize holes, so we had to recoat several holes (two more hours last evening). Here are a couple of pics of the rig. However, the bolts came out (relatively) easily thanks to the plastic tape wrap.


And here's a pic of one of the coated holes


At least, now we know how to do it for the next set of aka beams.

Akas: almost there

Three hours of work yesterday, in which we prepared the bolt holes in the aka beams with resin thickened with silica. The holes were drilled oversized (12 mm dia for 10 mm bolts, 15 mm dia for 12 mm bolts). We then covered the bolts with plastic tape, put them in the holes and filled the space with resin. Hope it works...

Akas (10)

Three more hours today. While Cinzia was fighting with the sander, I drilled the oversized bolt holes which will be coated with thickened resin.


I have some reservations towards those akas. First one is that those planks have several knots, a few of those being quite large. Are those knots going to be a problem, structurally speaking?
Second: they are heavy. I haven't measured the weight but based on sizes and specific weight of the fir, we should be close to 100 kg! I'm wondering if one could design a lighter system: nothing complicated, like a box section made of plywood and lumber. I sent an email to John Marples, we'll see what he replies.

Total work time to date: 539 hours.

Akas (9)

I really regret not having used a router from the beginning to smooth those edges, this is taking ages... Anyway, we're getting there. Three more hours today: we glued the doubler on the rear aka (300 grams of thickened resin) and continued to round down the edges.

Akas (8)

Five more hours in the last two week ends, still working on the akas. It's still cold so the garage is not pleasant to work in. Today we glued the doubler on the forward aka, using 400 grams of resin thickened with  microfibers. The photo shows the 3 still unfinished pieces, i.e. the rear swing arms and doubler, temporarily used as weights to press the doubler on the aka.
