attached is a simple sheet metal box with a cown cut in the top. I want to know how/if possible, the corners can be bent away from the body so that the bend is a full radius and the sides meet to close the corner. The bend should end approximately 3/4 away from the body at a 30 degree angle such that the max width is 8-1/2 from corner to corner.
Any thoughts? I am happy to reconstruct the top such that it is a closed roof bend up on all four sides.
