In the early days of the automobile, dashboard knobs were more than just functional controls — they were miniature works of art. By the 1930s, automakers had moved away from materials like Bakelite and began experimenting with new plastics such as Tenite, a translucent material made by the Eastman Company. This innovation opened the door to stunning dashboard details — knobs and steering wheels with beautiful swirls, depth, and light-catching translucence that gave car interiors the look of fine jewelry.
In his video (below), Keith Lee demonstrates how to recreate these classic details using modern materials. Whether you’re restoring a vintage car, building a hot rod, or customizing your ride, Lee’s step-by-step process makes it possible to duplicate original knobs with precision and beauty.
Using silicone molds and clear casting resins, he walks viewers through every stage of the process — from selecting an original knob to preparing the mold, mixing the resin, and achieving that classic translucent finish. With careful attention to color, clarity, and curing, the result is a faithful reproduction that looks right at home on a prewar dashboard or a retro-inspired build.
Lee’s method, refined over more than 15 years, allows enthusiasts to bring back the brilliance of early automotive craftsmanship. The finished pieces not only restore the look of the past but also showcase the artistry that once defined the golden age of the automobile interior.
