An apparatus for predicting the cutting performance of saws allows saws to be tested prior to installation in a sawmill and ensure that maximum cutting performance is obtained. The apparatus is used in a sawing device wherein a saw blade, either a circular saw blade or a band saw blade, moves past a sawing area at a sawing speed. A wishbone member is mounted for restricted movement perpendicular to a plane of the saw blade, the wishbone member having a slot therein in which the saw blade moves. Brake pads are provided on both sides of the slot in the wishbone member for applying a braking force on both sides of the saw blade moving in the slot, and a sensor determines linear movement of the wishbone member from a center position to determine deflection of the moving saw blade under the application of the braking force.
