Posterboard + CAD = Perfect Sheet Metal Air Box | '31 Ford Build - Video

In this video, I design and fabricate a one-of-a-kind sheet metal air intake box for my 1931 Ford hot rod using poster-board templates and a CAD-based design process.

Instead of relying on trial and error, I create full-size poster-board templates before transferring everything to a CAD program for sheet metal laser cuts. This method makes complex fabrication projects much easier to build.

Follow along as I walk through the complete process—from digital design and template creation to cutting, bending, welding, and final assembly—to create a custom air box that's both functional and visually unique.

If you're interested in sheet metal fabrication, automotive metalworking, CAD design, hot rods, LS swaps, or learning techniques that improve fabrication accuracy, this video is for you.
