Of course aboard Constitution the main deck guns are closer together and wouldn't have a much space to each side as the model shows. I added a couple of pin rails to fill the blank space.
Looking at the rigging now, I realize I should have waxed the thread. Not doing that was dumb and I knew better. The rigging was copied from photos taken of the 64 pound gun aboard HMS Victory. None of the Constitution's carronades show all the rigging the model provided and leaving it as coils on the deck didn't quite feel right after studying lots of deck photos.
It was a different, fun project.
