    That is amazing! No guides, free-hand all the way, apparently.

    Was he working to a line or did he just judge the thickness by eye?

    He had a mark at the corner he started at otherwise he eyeballed the rest. I was a bit concerned until the first plank fell over revealing a nice smooth surface. In the picture below he is slicing of the second board so the face closest to camera is a result of his first cut.

    That is amazing. Give him a chunk of ice and he could make decent change carving to-scale Taj Mahal's on a cruise ship.
    This guy is sooo good, he checks out the girl walking by while he's still cutting.

    Nice to finally see some curves! I think I cut the arms a little short on bulkhead #3 and I have some work to finish of on the other bulkheads but hopefully I'll be ready for a full dry assembly soon.

    "I think I cut the arms a little short on bulkhead #3"

    All the bulkhead arms should go to the top of the plywood/sheer. That way they tuck into the gunnel for strength. I have seen one GIS that has the same error and it sails fine, but the gunnel twists when you sit on it.

    I sail my GIS hard and would correct the error by scarfing additional arm material to make it long enough.

    Thanks John. I scarfed on some extra timber yesterday. It looked important enough to correct.

    Cheers

    Extended the arms of bulkhead #3 and glued up the bulkheads to the side panels. All went pretty smoothly with the help of my girlfriend.

    Regarding the bottom panel: when is the best time to coat the inside of this panel? Before or after it is glued to the hull?

    Maybe you could combine the two steps by coating (three coats, wet on wet) then gluing onto the hull while the third coat is still green. Spreading epoxy on flat in obstructed panels makes the going faster.

    I tried to predict where the glue surfaces would be on the bottom and masked those off before coating the bottom panel separately. I don't recommend that method. Better to just coat the whole dang thing and glue to the coated surface. More than one of my bulkheads are glued to cured epoxy with a raw strip of wood running along side the frame. (I've since coated those bare spots.)

    Plenty of builders have assembled first and coated after, so don't be afraid to go that route either.

    Aren't you supposed to assemble in a dusty stinky garage, not some incredible view balcony with swaying palms and the lake in the background?

    Is it too late to nominate this picture for the calendar?

    Thanks for your thoughts. Today I was doing a dry run to line up the center line of the bottom to the center of the bulkheads and then screwed the bottom in place with a single screw through each bulkhead and the stem. I took the opportunity to climb underneath and make the position of the bulkheads and chinelogs on the inside of the bottom panel - so I am going have a go at taping of these areas and then coating and sanding before I glue the bottom on permanently.

    Progress has been slow recently but I have the chinelogs planed down (today's dry fit pointed out a few minor areas that need additional attention) and everything looks pretty square.

    Glad to hear from you. Was a bit worried after hearing about the earthquake. How far from you was it?

    I'm not sure exactly sure how far out in the Pacific the epicentre was but it was at least 100km away from where we are. We got a decent shake here but there was no significant damage or injuries in our local area. If it had happened a month or so earlier at the end of the wet season (when the land here is saturated with water) - the story may have been different. We have had a few small after shocks but I haven't felt any of them.

    Another update photo - the bottom is on. Still going slowly (snails pace) - perhaps my goal of being on the water before Christmas was a little over optimistic.

    (Edit: for future reference the method of marking out the bulkheads and chinelog positions outlined in my previous post worked really well - all the un-epoxyed sections lined up where they were supposed to be.)

    Update: after a long hiatus I have been back working on the goat for the last two or three months.

    During this time I have finished the centreboard (that I started working on last Nov), made up the blanks for the boom and yard, mostly finished the mast and have just finished coating the mast step and partner and centreboard case. I hope to fit these into the hull in the next week.

    Work has disappeared for a while and the motivation is back so I hope to slowly progress through the rest of the build. Some photos of recent work...
