A method and apparatus for tensioning a continuous loop, such as a cutting blade installed on a band saw having a frame, a manually rotatable tensioner, a first pulley rotatably connected to the manually rotatable tensioner, a second pulley spaced away from the first pulley, and a cutting blade strung between the first pulley and the second pulley, generally including the steps of positioning an adjustable body, such as a reciprocally actuated rod, between the manually rotatable tensioner and the second pulley, extending the adjustable body in a direction away from the second pulley and toward the manually rotatable tensioner so that the manually rotatable tensioner and the first pulley move in direction away from the second pulley, withdrawing the adjustable body in a direction toward the second pulley so that the manually rotatable tensioner and the first pulley move in a direction toward the second pulley.
