Square out the corners (click to open/close)

Using a scalpel square out the corners. You are looking very close to the model so the square looks rough. At normal view the edges look clean and sharp.
Giving the port a sharp clean look (click to open/close)
When the planking is glued to bulwark the ends and lower edge of the planks form the sides of the sweep ports. This gives the port a sharp clean look. Looking at the picture this close you can see the wider first plank which defines the size of the port. If you were to use all the same size planks a notch would have to be cut in the next plank up. On the left the plank ends were cut and sanded to the edge of the gun port side. At the top of the bulwarks the top timbers will be trimmed even with the last plank.
