Turbo Derby ULTIMATE Pinewood Derby Car Axle Hole Drilling Jig
Designed for maximum flexibility, Turbo Derby has released the ULTIMATE Pinewood Derby car axle hole drilling jig, which is the most versatile drill jig on the market! With 16 hardened tool steel bushings, the Turbo Jig ULTIMATE is made for drilling holes for Pinewood Derby axles. It can drill three different wheelbase lengths with straight front holes OR built-in steer!
Ideal for Rail Riding
The Turbo Jig ULTIMATE is set up for rail riding/running and is ideal for racers who may race under different rule sets (e.g., Pack, then District), where one set may allow bent axles and the other may not. Use the straight bushings to drill a straight front hole to allow for a bent steer axle. Or use the steer side bushings to drill the car with a preset amount of camber and toe on the front wheel to achieve a steer amount of approximately 5 inches over 4 feet.
The Turbo Jig ULTIMATE can drill wheelbases of 4.375 (stock BSA block), 4.75, and 5.0 inches! The ULTIMATE Jig also comes with an integrated clamp, ensuring the block is firmly in place while drilling holes for Pinewood Derby axles!
Consistency and Easy Drilling
For greater consistency, confirm that your block is centered in the jig before drilling. A small shift can throw off alignment and impact how the car tracks down the rail. With the Turbo Jig ULTIMATE, it’s easier to drill clean, repeatable axle holes, then fine-tune steer and stability during testing at home.
The Features of This Pinewood Derby Car Axle Hole Drilling Jig:
16 hardened tool steel drill bushings
Designed for building rail riding/running cars
Drill both straight AND built-in steer (camber and toe) front axle holes.
Drill 4.375 (stock), 4.75, and 5.0-inch wheelbases without moving the block!
Removable clamp
Geometry for perfect alignment (rear axles, fore/aft, side to side) is built into the jig.
Integrated gauge to ensure correct bend amount in the front axle for rail riding (if not using the built-in steer option)
Checks fore/aft and side-to-side alignment
Non-dominant (left side) front axle holes are 0.01” higher than the dominant (right) side front wheels to ensure non-dominant wheels don’t contact the track.
PLEASE NOTE: Practically none of the stock axles are straight, and the heads are often not square to the shaft. This will affect how much the car steers. It is advisable to check the steering of the car when using the built-in steer option on this Pinewood Derby car axle hole drilling jig. Rotating both the steer wheel axle, AND the rear axles will change how much the car steers. Tune these until you reach the desired steer amount.
