The Derby Worx Pro Axle Bender is a fully adjustable Pinewood Derby Axle Bender that will give builders a wider range of bend angles. By simply adjusting the stop collar with a 3/32″ hex wrench, bend angles of 0.5° to 10° can be achieved for a widest range of tuning options ever. The tool features a blade & fork design pivot for accurate tracking and Derby Worxs exclusive Bending Cup which allows the new oversize stainless steel & titanium axles to be correctly bent without adding a groove or notch at the desired bend point. The main shaft has 3 machined rings which when matched with the provided bending chart takes the guess work out of axle bending of axle bending and makes setting up your cars for a Rail Rider or a straight on alignment a snap!
The Pro Axle Bender is a fully adjustable precision tool designed to bend all Pinewood Derby Car axles for alignment and tuning. Its unique cup-in-lever design prevents distortion in multi-groove axles and eliminates any additional grooving at the bend point for stainless steel axles. Derby Worx recommends using the Rail Rider method for ease of set up and maximum performance.
To use the Pro Axle Bender, you will need a 3/32 hex key wrench, a pointed Sharpie marker and prepped racing axles. (All burrs removed and polished)
1. Make a dot on the axle head with the Sharpie. This will be your reference mark for the bend as well as for installing and adjusting the axle in the car.
2. Measure 3/8 or .370 from the axle head and place a dot on the axle shaft in line with the dot on the axle head. This is where the bend will occur and will provide the proper amount of axle for the wheel hub to ride on. This distance is a good reference for B.S.A. wheels, other wheels may require different bending points, and the tool is designed to accommodate all wheel types.
3. Loosen the knurled thumb screw and lift the clamp cap. Insert the axle through from the inside placing the axle head in the cup machined in the lever. Place the dot on the axle head up at 12:00 and the dot on the shaft at the edge of the clamp cap and firmly tighten the knurled knob to hold the axle.
4. Using your 3/32 hex key, loosen the set screw in the spring collar and slide it to the mark for the desired degree of bend and tighten.
NOTE: The bend chart is a guide line; always try a test axle first. If not possible, bend in small increments for the first axle.

5. Place your thumb on the black knob and pull the lever smoothly and steady with your index finger until the spring fully compresses to bend the axle.
TIP: A small amount of racing lubricant in the axle groove on the lever
will make for a smoother bending.
