Tacked together, the end and center begin to look like a bumper.
The next section to be created is the bumper's outside edge (the piece that runs toward the rear wheel). After tracing that template to the sheet, Marc trims it out on the power shear.
Marc uses the same dies as the bumper's center section to start with, but here finishes with the shaper to bend the ends over to the desired arc.
Not quite satisfied with the machine work, Marc goes to the stump to make it right.
