Inspired by the iconic crime-fighting vehicle, this project details the creation of a custom Batmobile Car for a Pinewood Derby race. While designed for an adult open class, this intricate design may not adhere to official Cub Scout regulations. This guide offers a step-by-step walkthrough of the design and construction process.
The project began with a custom-made pine wood block, significantly larger than the standard Pinewood Derby kit block. Two 2.75-inch wide strips were ripped from a 1×6 pine board and glued together to form the base.
Shaping the Batmobile
The Batmobile’s silhouette was transferred to the wood block using a paper template. A bandsaw was used for the initial rough cuts, intentionally leaving excess material for later shaping.
A crucial step involved creating a 3/8-inch deep slot underneath the car body to accommodate the wheels and allow for the low-hanging design elements. This slot was precisely cut to the width of a standard Pinewood Derby car (1.75 inches). Ideally, this slot should be cut before shaping the body.
Refining the Design
After the initial cuts, the side profile was traced onto the body and cut out. Detailed guidelines from the template were then transferred onto the wood to guide the intricate carving process. A combination of coping saws, drill bits, chisels, and a Dremel tool were used to gradually refine the shape.
Wheels and Axles
Axle slots were cut using a hacksaw, though doing this earlier in the process, when the block was still square, would have ensured better alignment. Wheel wells were created by routing out circular holes with a hand router.
Finishing Touches
The body was meticulously sanded smooth, first with coarse grit and then with finer sandpaper. After masking the wheels, primer and glossy black spray paint were applied. Detail painting completed the Batmobile look.
The Final Batmobile Car
The final Batmobile car is a testament to creative woodworking and a passion for the iconic vehicle. Though race performance was less than stellar, the unique design was a standout.
