               a handle lever having a first end and a second end;                    
               a gripper carried by the handle lever and engageable with a            
          sidewall of a cylinder to locate and anchor the tool relative to            
          the cylinder;                                                               
               a compressing lever, a slot in one of the levers, the                  
          compressing lever connected to the handle lever for movement
