  • Surface abrasion tool
    Patent number: 8845397
    Abstract: A surface abrasion tool (12) has a first drive shaft (42) connect a motor (14) to a power transfer assembly (20). The power transfer assembly (20) transfers rotary power from the first drive shaft (42) to a second drive shaft (46) which is spaced apart from and parallel to the first drive shaft (42). A sanding disc (26) is secured to the second drive shaft (46). A linear drive means (16) is mounted in fixed relation to the motor (14) and selectively moves a pressure plate (22) relative to the sanding disc (26). A locating pin (28) extends from the pressure plate (22) in opposed relation to the sanding disc (26) and fits within a hole in a work piece. The linear drive means (16) is actuated to push the sanding disc (26) into a side of the work piece opposite the locating pin (28).
