How did they build? First good answer instant 10 points.?
In the medieval times, how did they build the cannon 'Pot De Fer'?
An image can be found here, this is an experimental one built a few years ago, i was just wondering how they managed to get the shape in the medieval times.

Did they use a mold for it or did they somehow bend a piece of metal into the shape?
Any suggestions would be appreciated.
