I took a workshop, angular metal sheet class.
We used couple of machines bellow.
>Hydraulic shear
>Turret punch
>Slitting shear
>Corner notcher
>Finger brake
>Spot welder
And we made box with metal sheel.
At first, I sheared metal sheet with Hydrauic shear.
Then I made hale with turret punch.
I bend edge.
And bend with brake.
Finally, I weld edge with Spot welder.
I enjoyed making for 3 hours!
The box looks useful.
