Fairing the deck edges (second ama)

We're just back from a business trip to San Francisco where we attended the American Geophysical Union Fall Assembly. Today I worked one hour to fair the deck edges of the second ama using mostly the power plane but also surforms and rasps. Here is how the second ama looks like now (after removing the sawdust all over the place)

We still have to fair the edges with sandpaper.

Total work time to date: 220 hours.

All glued (2nd ama)

Today is an holiday so we could spend two more hours to remove all the screws, glue the round pads to the deck, and fill all the screw holes. About 300 grams of resin were used.

Total work time to date: 219 hours

Second ama deck glued

Six hours this week end. We first cut the hatch hole on the deck panel.

We then faired the deck stringers on the hull with power plane, Surforms and sanding board, checking the planarity from time to time.

The round pads were faired and sanded, ready to be glued on the deck

At the end we glued the 12 mm deck (on which we had prebored the screw holes) on the hull, using 2.5 cm long screws on 15 cm centers. This required almost 1 kg of thickened resin. About 200 grams squeeze out from the joint on the outside and is cleaned right away, but probably the same amount squeezes out on the inside and will remain there forever since it's impossible to reach inside except around the hatch hole.

Total work time to date: 217 hours

Epoxy coating, butt blocks (2nd ama)

Two hours this evening to glue the deck butt blocks to the deck panels, and to give the first epoxy coating to the inner side of the deck. Tomorrow morning we'll give a second coat, and maybe we'll glue the deck.

Total work time to date: 211 hours

Cutting the deck (2nd ama)

Four hours this weekend, in which we scribed and cut the deck for the second ama, as well its butt blocks. We cut a 12 mm panel in two halves lengthwise, drilled the stud holes in the right place, and scribed the shape from underneath

We then cut the panel with the badass jigsaw

I also cut he two butt blocks (the distortion here is due to the perspective, luckily enough)

And here is the deck ready to glue

I also gave a first fairing to the deck stringers with the power plane.

Total work time to date: 209 hours

Coating the interior

Four hours in the last two days to give the ama interior two coats of resin, to glue the steel studs and the stem piece.

Here's a general view

Next will be fairing the deck stringers to get ready for glueing the deck panels.

Total work time to date: 205 hours

Here we go again (second ama)

During the past week Cinzia worked a couple of hours to fair the first ama hull.This morning we swapped the two amas: the first one, done, has been put aside on sawhorses, while the second has been put on the cradles. The two of us can move the completed hull around quite easily. It probably weighs around 40 kg, but we haven't measured it.

Today we worked 4 hours (so we passed the 200 hours mark), mainly to draw, cut and glue (as usual, using microfiber thickened resin) the three bottom butt blocks, In this pic you can see the various weights that we've used to press the butt blocks down.

Total work time to date: 201 hours
