i am doing some sheet metal work, and i need to flare the end of some pieces so that the others will fit inside them. basically, lets say i have a 12" x 6" 16 Ga box that i want to match up with another 12" x 6" box. i basically want to flare teh end of one out by the thickness (1/16') for a length of 2-3" so that i can slide one inside the other and rivet them together.
is ther an easy way to do this? i have looked at forming tools, but not sure. i have tried to model the part as a solid, then convert to a sheet met al part, but it didn't work. here's a pic of what i'm trying to do
