After writing a fair bit of promotional fluff over the last few days (sorry sorry sorry) finally something of substance.
I have separated the pics of the Eureka that was built at the Duck Flat Autumn School over the last few weeks and commented any interesting bits.
We did use a slightly different method in some places compared to the plans method. None of the below is (in particular) better than what is in the plans, but if you like the idea and understand what we were getting at then .... why not.
Bob the builder had some understanding of tools (orthopaedic surgeon) - though he kept pointing out that his were not covered with epoxy!!!
All the pics are here

the comments on the pics in this set are more detailed than the comments below with many cautions and caveats. So please read.
But some interesting processes.
We made one of each type of panel from the boat and used it to mark out the other which were cut with a small margin. Then we screwed everything together and used a router with the accurate one on the underside to act as a guide. One mistake with a router and your two and a half sheets of ply are firewood.

We used the Chesapeake Light Craft Method of stitching the bottom three panels but then making the two upper panels as a separate assembly and kept them stable on top while stitching with two pieces of horizontal timber between the two.

We used mini fillets between the copper stitches then removed the copper wire the next day. Then went over the mini fillets with a big clean fillet.

Covered with a big neat fillet

The plywood was all pre epoxied and sanded before assembly so that made it easy to remove excess glue without staining the timber.
The problem with the fillet method is that up in the bow two of the panels that make the topside have little angle between them at the join. So we used glass tape to reinforce that area laying it down into a wet fillet before brushing with resin. Because this area (was carefully measured to make sure that it) would be inside the buoyancy tank it wasn't necessary to tidy up much.

If you don't read the notes in the photo series ... you only have yourself to blame if you try the methods above and below and find problems.
The main change was to simplify the fitting of the decks. Fitting them inside the hull skin is a tricky cut and try and slowly trim type procedure. So we removed the hull sides to the depth of the ply using the router after the deck supports had been glued in - (they were the guide for the router bearing).

Then when the decks went on the end grain would be covered by the gunwale. The gluing process for this was trickier, longer and more complicated than I liked but we were under some time pressure. Only ended up with three screw holes in the deck and it all flexed into place pretty easily.

The beauty was that the deck edge was a lovely tight fit against the gunwale so it looked like a master craftsperson - rather than a lazy builder like me and a new builder like Bob working together.
All in all it was a pretty pleasing 10 days of building.
