Key Features of the G&S Tire Grinder
- One motor turns all axles
- Only two screws to remove/replace the entire grinding assembly for different grits
- Screws beneath the ball bearings to adjust parallel
- Spring loaded axle carrier to allow "grind and release" truing methods with ease
- Indicator knob for precise repetition of tire diameters as needed
- Consistent tension of o-rings due to double-pulley design
- O-rings can easily be moved side to side to accommodate various axle configurations
- standard 1/32 bushings snap into axle carrier, but V-shape still allows smaller or larger bushings or bearings to stay in place
- Distance between sanding drums accommodates most 1/24 and 1/32 wheels/axles
- sanding surface cannot contact axle pulley/o-ring
