The other and last section, I J, of Figs. 6 and 8, is to be placed at a distance of 3 ft. aft of the amidships, and should be made of two oak ribs of the shape shown in [Fig. 6], which should be 3⁄4 in. thick, and not less than 11⁄2 in. wide in the weakest place. The notches required are—(11⁄4 in.,) 23⁄4 in., (11⁄4 in.,) 21⁄2 in., (11⁄4 in.,) 7⁄16 in., (11⁄4 in. A,) 13⁄8 in., (11⁄4 in.,) 17⁄8 in., (11⁄4 in.,) 21⁄4 in., (11⁄4 in.,) 3 in. keelson, and on the other rib the same.
A small triangular piece of 3⁄4 in. oak should be fixed at the upper end of the stem post, to which the two upper laths and the gunwales may afterwards be fixed. The shape and size are shown at M in [Fig. 8], on [page 271].
About thirty-five hours will now have been spent in the building of the boat, and a casual observer would not be justified in asking what was being made, for the shape of the boat has now become apparent.
In order to prevent any mishap during the building, it is advisable to screw a strip of deal across from side to side of each section, and these strips can also be used for adjusting the position of each section, for if a small hole is bored in the exact centre of each strip, as well as in the bows and stern, and a small wooden peg be placed in each hole, it can be easily seen if the sections are in their proper positions, for, if they are so, the pegs will be in a straight line; and, if not, one or other of the sections will require adjusting until they are so.
The wood for the laths, keel, and gunwales will now be required; these, of course, will be obtained from a builder or sawyer.
Elm is the best wood of which to make the laths, as it is capable of being bent into almost any shape when steamed; in fact, it will be found as well also to make the keel and gunwales of elm, and if this be decided on the cost of the material and sawing of the laths, etc., will be 10s.
The lengths for the laths will be—six, 13 ft. long; six, 12 ft. 6 in. long; and ten, 9 ft. long; all 11⁄4 in. wide and 1⁄4 in. thick. These must all be planed on the one side and the edges.
The keel should be sawn 11 ft. 3 in. long, 3⁄4 in. wide, and 2 in. deep, and afterwards planed, the bow end being cut to suit the curve of the bows, and the stern end to the bend of the stern.
The gunwales are each 12 ft. 6 in. long, and 1 in. square, and are planed on three sides.
