Just because getting the wheels to go straight was such a hassle, and this solution was so straightforward. Instructions 1. Place the axle guide directly into the slot that's specifically designed for it. 2. You should feel a small lip on each side of the car when the guide is installed correctly. 3. Position the car and axle guide in a clamping device to keep both securely in place. 4. Start driving the nail into the slot, keeping it aligned as much as possible while hammering away. 5. Drive the nail firmly home, and the axle guides will keep it going straight. 6. When the wheel makes contact with the axle guide, you know the nail is in far enough.
