FIG. 10 FIG. 12 FIG. 14 Bulwark plate clamped in position to determine bottom edge line. FIG. 11 Clamping at stern showing variety of clamps that can be used to hold hull flair curvature. FIG. 13 The transom plate looking inboard aft. Bulwark plate clamped during gluing. Starboard bulwark plate mounted. 10 The bulwark plates are laser cut from 1/32” plywood. These pieces have the gunport and oarport openings cut into them (see figure 10). The bow, stern and bottom sides have been left oversized to allow fitting to the framework you have built. The top edge has been accurately shaped to the top bulwark line. The gunport openings are cut slightly undersize to allow proper sizing to the gunport frames which will be mounted later. The first thing to do is establish which are the lower edges of the bulwark plates. The gunport openings will help. They are numbered 1 through 11 from bow to stern. Gunports 5 and 11 should be centered vertically between bulkhead extensions “I” and “J” and “T” and “U” respectively. The top edge of the bulwark plate has to be 25/32” from the top of the deck plate at bulkhead “T” and 31/32” at bulkhead “I.” An additional height check can be made at bulkhead “A.” It should be 13/16.” With the bulwark plates set at these dimensions and clamped in place, a line should be drawn inboard along the bulwark plate at the top of the deck plate. The bulwark plate can be removed and cut to this line, which establishes its bottom edge for assembly. The plates are then remounted to the bulkhead extensions with clamps at the proper fore and aft, and vertical settings and glued in place with slow-set Super glue (see figure 11). They should be clamped at each bulkhead to be sure they conform to the tumblehome and flair curvatures along the hull (see figure 12). It can be advantageous to glue in the bottom edges before clamping to the bulkhead shapes above deck. To aid in positioning these bulwark plates, you should refer to the plans and use the following table as a guide (Also ... the bow ends tend to flair upward and should be held firmly in place): Bulkhead Top edge above deck plate A................................13/16” B....................................“ C................................27/32” D..................................7/8” E................................ 31/32” F.....................................“ G....................................“ H....................................“ I......................................“ J......................................“ K................................15/16” L.....................................“ M...............................29/32” N............................... 27/32” O..................................7/8” P.....................................“ Q................................27/32” R....................................“ S.................................13/16” T................................ 25/32” U..................................3/4” V................................11/32” Note: These dimensions are taken along the outer curved surfaces of the bulwark extensions which are longer than the vertical height from the edge of the deck plate. These dimensions are for reference only and depend upon the accuracy of the deck plate level. A true line is more important than an actual conformation to any reference dimension. In addition, the bulkhead extensions should be aligned externally to give a true line to the bulwarks (see figure 13). If some are below a true line, they should be shimmed with 1/8” wide basswood stock. Those that may be too “fat” should be trimmed down. The 3/16” width of these extensions will accommodate any trimming easily. Gross bumps or indentations are not the intent of the ship designer, builder, historian, kit designer or modeler. 7. Transom The transom piece is also laser cut from 1/32” plywood. Its top is cut to the design curvature and the gunports are also cut as they were in the bulwark plates (see figure 14). The bottom and side edges have been left longer to allow fitting to your assembly. This piece should have a vertical centerline drawn on it between the gunports.
FIG. 15 FIG. 17 Stern blocks filed to the slope of transom. Gun and oar port frames amidships. FIG. 16 FIG. 18 Gunport frame clamped at bow. 1/16” square filler strips amidships. Align the transom center with the deck centerline and the top edge with the aft top corners of the bulwark plates. A line drawn across the deck plate will define the bottom edge of the transom piece. When cut to this line, it can be realigned, held with tape and glued in place along the bulwark and deck plates. The port and starboard edges can then be trimmed down flush with the after ends of the bulwark plates (see figure 15). If your frame assembly is square and level from bow to stern, the transom will be square if properly aligned. Its shape may have to be altered to give this squareness and alignment with the bulwark plates. If the shape needs to be altered, be sure to keep the transom symmetrical from port to starboard, as nothing shows up with more stigma than the transom if it is tilted. 8. Inner Bulwark Preparation Giving the bulwarks the proper thickness for support and the framing for any openings is the last bulwark detail chore to be done before starting the hull surfacing. Frames for the gunports and oarports have been laser cut from 1/16” plywood. The gunport frames are opened to the proper size and must be centered over the openings cut in the bulwark plates. They should be clamped when the glue is setting to hold them to the curvature of the bulwarks (see figure 16). The oarport frames are also cut to an accurate size and should be glued over their matching openings in the bulwark plates. The bulwark gunport openings can be cut to the inner edges of the gunport frames with a #11 blade. The oarport openings can be filed to even edges with a square miniature file (see figure 17). The transom gunports are treated in the same manner as the bulwark gunports. Any framing that may extend over the top of the bulwarks or butt into a bulwark extension can be cut to a proper fit. These frames establish the bulwark thickness but do not control thickness at the top and bottom edges. For any long top or bottom edge opening between the frames, the support for the railing and the inner bulwark planking is supplied by 1/16” square basswood strip stock (see figures 18 and 19). The strips mounted at the deck level also provide a supporting gusset to the bulwark plates when the bulkhead extensions have been cut down to the 1/16” thickness at a later stage of construction. At the bow are additional strips to support the inner planking around the curve. And at the forward lower end, 1/16”- thick plates are added in the area where the hawse holes should be drilled 1/8” in diameter (see figure 20 and plans).
