Attach with the channel resting on top of main wale No. 5, the forward, outboard corner of the piece about 1/8 in. forward of the first gunport in the middle row. The main channel is 3 in. long between bevels and the same in width and thickness as the first channel. It also rests on top of main wale No. 5, its corresponding forward corner exactly in line with the forward side of the seventh gunport aft in the middle row. The mizzen channel is 1 3/16 in. long between bevels, 1/8 in. wide and 3/32 in. thick. Flatten main wale No. 1 sufficiently from the quarter-gallery dome forward, to give this channel a good seat. Then glue and pin the mizzen channel in place, directly over the vertical side of the wale. The fore and mizzen channels are likewise glued and pinned to the hull with headless lill pins, driven through their beveled ends. You may make either working or dummy gunports, as in Fig. 33. Fig. 35 shows a jig to hold the gunport covers while you drill small holes through brass and wood for pins, using a vise. /use the clothespin jig as in Fig. 36 to hold the cover and hinge assembly securely, while applying a drop of solder to each end of the hinge pivot. To attach the working gunport covers, insert a thin blade between the wale and hull centrally above the gunport. Then slip the wide section of the hinge under the wale and remove the blade. Try the cover in the gunport to make sure that it fits flush on all four sides. Now, with the cover closed, use the pin vise to drill through the wale and brass to the hull, after which a pin is driven through both, the pinhead clipped off and the end riveted over with light taps of a ball-peen hammer.
