Mini 4WD Wheel Balancer Jig and Wheel Slicer Jig for weight reduction and improved running stability. Significantly improves straight-line performance and stability during jumps. ★ Mini 4WD Lightweight Processing Jig Wheel Slicer By lightweighting the wheels, you can achieve greater weight reduction than usual. The wheel width after cutting will be approximately 9.1mm (with some variation). (The tire section will be approximately 8.1mm wide) For wheels with diameters of approximately 25mm, 23.5mm, and 20mm. If the wheel is loose when setting it, there is a slit in the center of the main body, allowing you to secure the wheel by sandwiching it. (In that case, you can use a 30mm long screw for Mini 4WD to secure it.) If necessary, wrap masking tape or similar around the wheel for processing if it's loose. (Tightening too much may damage the wheel) This listing is for the jig body only (wheels, fixing screws, etc. are not included). ★ Tire Wheel Balancer Jig Tool (Magnetic Type) Compatible tire diameter: 22-38mm This is a balancer jig tool for adjusting the balance of Mini 4WD tire wheels. Set Contents ・Jig tool body ・Magnet ・Shaft ※ The shaft is cut to fit this jig and can be used immediately. (Please prepare the wheels and tires) Balance is achieved by floating one side of the shaft axis in the air, with low rotational resistance. 【How to Use】 1. Set the tire wheel to be balanced by passing it through the shaft. 2. Confirm that the shaft rotates lightly with only one side floating. 3. Wait for the wheel to stop rotating, and the heavier side will come to rest at the bottom. 4. Mark (indicate) the upper part. 5. Attach weights (masking tape, etc.) to the wheel rim (inside) where you marked. Shaving the wheel has the same effect, but it's quite sensitive; masking tape is recommended. 6. Rotate again and repeat steps ③ to ⑤ to adjust. 7. When the balance is achieved, the stopping point becomes ambiguous, and it becomes difficult for the rotation to stop. This is the completed state. After processing, you can feel a significant reduction in vibration when you set the tire wheels on the machine and turn on the switch. This product is made using a 3D printer for the main body.
