Filling the weave: akas

After more than one month here we are again... Two hours today to recoat the two akas and two of the fours swing arms with clear resin to fill the FG weave. We had previously washed the blush away.

We'll do this to all fiberglassed surfaces, and then we'll prime and paint.

Total work to date: 609 hours

Washing the blush from the akas

We are back after one month... too many things to do. Anyway, just one hour this morning to scrub away the amine blush from the akas, which will be the firts pieces to be primed and painted. We used a brush and a Scotchbrite pad with running water.

We'll then power sand everything, fairing with putty where needed.

Total work time to date: 607 hours.

Deck seats (10)

Three hours today do give a double coat of clear resin to the upper face of the deck seats. We first completed sanding the surfaces with 60 grit to remove epoxy putty residuals all around and 120 grit to finish. We used about 800 grams of resin. The plywood edges suck a lot of resin so one has to pass the brush along several times. We gave the first coat at about noon and the second one at 6 pm. Here's how it begins

and here's how it looks at the end

Deck seats (8), crush plates

Five hours today, so we hit the 600 hours mark!
This morning we both worked on the seat decks, rounding edges and grinding epoxy drips, using power plane, power sander, surforms, rasps and sandpaper. Hard work indeed.

In the afternoon, together with my friend Franco Toscano, who professionally builds high end astronomical telescopes in Matera, we built the sixteen "crush plates". Those are square (75 mm sided) pieces of 6 mm thick aluminum, and are supposed to work as washers on steroids. Four of them (with a 12 mm dia. central hole) are going on the outboard ends of the swing arms, where those are connected with the steel studs on the akas' decks. The other twelve will go here and there around 10 mm dia. bolts.

Total work time to date: 600 hours

Deck seats (7), outboard mount

The idea of having the two deck seats only glued to the low side of the coamings made me a bit nervous. I know, epoxy is fantastic but, just in case, we decided to secure the two seat platforms to the coamings with 5x40 mm ss screws on 15 cm centers... We also glued two 6 mm plywood pieces on both sides of the outboard mount beam. Here's a pic showing both things.

Total work time to date: 595 hours.
