Building a ’30 Ford Channeled Sedan
Part 2: Sheetmetal Modifications
T

he last article examined the outstanding chassis Roadster Shop built for Gerry Kerna’s ’30 Ford Model A Sedan. This time, we’ll look at the equally impressive body modifications by Roadster Shop.

While the sedan has a traditional look, there has been a lot of attention paid to every detail, and a great deal of careful work was put into getting the proportions just right and sculpting the sheetmetal panels to a very high level of precision.

Most of the roof above the windows was in such poor condition that it made sense to replace it with new metal. The original driprails were removed and a beautifully shaped bodyline was made to replace them, giving the roof a much smoother look.

Model As were manufactured with a composite fabric roof insert. Roadster Shop put a lot of work into making a custom-formed steel roof insert with proportions more like a ’32. Rather than simply welding the roof insert into place, it was carefully fitted to the flanged opening made in the new roof panels, adding a unique feature to the car’s styling.

The panel above the rear window and the windshield visor were extended a few inches toward the center of the roof, giving the insert better proportions.

A Brookville Roadster grille shell was fitted to the front of the car, centered over the front axle. The shell was chopped 1-1/2 inches to give the hood top the correct slope and a custom C&R aluminum radiator was ordered to fit. The careful layout of the chassis ’rails, keeping them low to the ground, allows the bottom edge of the hood sides to be nearly level, avoiding the awkward ‘uphill toward the front’ look that many fenderless sedans have.

Much work went into refining the smallest details, such as smoothing the vertical seams on the rear body panel and blending the visor seamlessly into the surrounding sheetmetal.

After Roadster Shop had completed all these modifications, the car was shipped to Creative Rod & Kustom in Pennsylvania for the finishing touches. We’ll look at some of their work in the next installment.

3. The original wooden windshield header was in such poor condition that it will be replaced with a steel reinforcement.
wide flange added to the rear edge of visor
4. The original visor will be reused. A wide flange is being added to the rear edge to match the custom ’32-style roof insert that Roadster Shop will shape.
pattern sheets laid over upper roof sections
5. The upper roof sections were in poor shape, with rust and distortion. Patterns were made to shape new metal to replace these sections, eliminating the driprails.

6. The replacement roof panels were made from 18-gauge steel. These were shaped on a Yoder power hammer and the contours were refined with a ProLine planishing hammer.

masking tape on the replacement roof panel
8. Masking tape is used to lay out a bead on these panels, which will follow the contours of the original driprails.

ERCO Machine being used to turn a 1/2-inch flange around the panel’s perimeter
18. Once the fit of the roof insert was perfected, an ERCO Machine was used to turn a 1/2-inch flange around the panel’s perimeter. This insert will be a separate panel, and the uniform gap around the edge will become a tasteful design feature.
