On the left is the Tea-Tree crook selected for floor #3 (shown with its pattern in the previous post). I've just planed it true and flat and to 2 3/4" thickness. After this I bevelled the sides and bottom to angles lifted from the boat, offered it up for a trial fit and kept whittling down the high spots until all three surfaces were bearing fairly on the planking and keel. I then drilled limber holes (for drainage) on both sides, and marked and cut the top for a fair curve. I primed the mating surfaces and then clamped it in place and drilled it off for fastenings through each plank that it lands on (2 1/2" Monel screws down low, 5" and 6" copper nails roved over through the higher planks). I fastened it off on a bed of thickened primer.
The photo above right shows floor #6 almost ready to prime. You can see that it is laminated from a number of components: three laminations of Spotted Gum totalling about 1" in thickness were laminated against the hull planking, a thicker group of Spotted Gum laminations was then bent and glued up around metal brackets on the bench, then fitted over a filler block of Spotted Gum and some packers of Huon Pine, then both sides were cleaned up and the floor thicknessed to 3 1/2". The photos below show three of the floors fastened in and two more clamped in place ready for drilling. All of these floors will be notched on their upper arms to house the lower stringer, seen here temporarily clamped out of the way.
