The lowest ports have their bottom edges flush with the bottom edge of No. 5 hull lift. Fig. 28 shows how the gunports of each line are staggered and gives dimensions for locating the gunports in each line. Check your complete pencil layout again to be sure that each port is correctly placed, before you begin to cut.
With a very sharp jackknife, cut deeply along each side of each gunport as marked. Then, use a 1/4-in. carpenters' chisel to sink the holes. These must be cut into the hull squarely to a depth of 3/8 in. to receive the inboard ends of the guns, which will be described later. Don't overlook the two holes without squares just under the quarter galleries. Now, make a tool, shown in Fig. 24, to undercut all sides of each gunport about 1/8 in. deep as in Figs. 23 and 24. The object of the undercut is to produce a hollow appearance of the interior as viewed from the outside.
Two quarter galleries are next made, one for each side; see Figs. 26 and 32. From white pine, cut four blocks, 2 9/16 by 1 1/16 by 1/2 in. in size. Cut two more blocks of the same thickness, but 2 3/4 in. long and 1 3/16 in. wide. One end of each block is cut dome-shaped as shown. Note that greater curves are cut in the two larger blocks. Now, on the flat back side of two small blocks, measure down 1/2 in. from the point where the dome curve meets the vertical side. Draw a line straight across each piece and, from this point down, cut away the wood so that only a 3/32-in. thickness remains as the outboard side, as shown in Fig. 32. Glue the blocks together, as shown, in sets of three, one large block between two smaller ones.
