A medieval style cart my team made for a New Orleans Mardi Gras parade. The finished size was about 6 feet high, 4 feet wide, and 10 feet longl. It was made from solid cypress and we did all of the metal work as well.
I forgot to add that during the initial design process we were under guidance from a guy from the Prince's [Charles] Foundation who is trained in medieval carpentry.
Thanks for the support everyone. We actually did have a spear, but i don't have any photos of it. And Steve, sorry but I don't have any plans or anything would be willing to offer some input though if you ever decide to build it.
