cutting, trimming and installing the parapets took longer than building the bastions did
Of course a fortress isn't all defense. It is armed with a multitude of cannon. These need to be able to bear upon the enemy and thus require gunports. lots of them. Having learned while building my model of Fort Matanazas that drafting them onto the assembled model was difficult I decided to create a template to aid in the drafting of the ports.

It is simply a bit of heavy card with the geometry already worked out so that all that is required to get a set of perfectly matching gunports is the simple act of tracing it onto the parapet.

but once I had it figured out drawing identical gunports was a breeze
