Form two other sheets in a similar manner for the two sides, and
of the shape of fig. II. The dotted lines a b c d e f, fig. I., show the
portions of the tin round the edges, 1 inch wide, which must be turned up
at right angles with the bottom, and to which the sides are to be
soldered on the inside; they should have triangular pieces clipped out of
them, as shown in the fig., where the bends of the boat begin, to make
them take the curve required. The two extra pieces at the ends a d, e f,
2 inches wide, are for turning down over an iron rod, which is to pass
round the gunwale, to give stiffness to the boat; g h, fig. II., is a
breadth of 2 inches of extra tin, for the same purpose of turning down
over the iron rod.
"Each side is now to be soldered to the bottom piece, beginning with the
centre, and working in to each end.
"The soldering of the turned-up edges to the bottom, on the outside, may
then be done. Separate slips of tin 2 inches wide should then be bent up
longitudinally in halves, like angle-iron, and fitted along the joining
of the bottom and sides, on the inside, and soldered; these slips may
also be clipped on either side, when necessary, to make them take the
curves.
"The measure round the gunwale may now be taken within the edge of the
tin, and an iron rod 3/8 of an inch thick, to go round this gunwale, bent
to the form of the outline of fig.
