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
