LAPTOP FOLLER, EXCENTRIC BALANCE SHAFT FOR A LAPTOP FOLLER, AND BALANCE SHEET FOR A LAPTOP FOLLER. A skinner (10) including a pneumatic motor (24) that drives a pair of disc blades (12) has opposite cutting oscillations and a governor that controls the motor speed (24). Regulator balls (122) acting as centrifugal weights rotate with the engine (24) and push against a slanted flange (121) on a valve head (108) to move the valve head (108) towards a seat. valve (106). The movement of the valve head 108 comprises a bias spring 112 and restricts the flow of pressurized air when the desired velocity is exceeded. When speed decreases, centrifugal force decreases and bias spring (112) opens valve to provide additional power to motor (24). The disc blades 12 are provided with a cylindrical center edge which substantially increases the area of the center bearing over which the blades 12 rotate, and produces significantly longer blade life.
