The cutting edge of a bandsaw consists of a continuous, welded-steel blade that rotates around an adjustable wheel up top and a drive wheel below the saw's table. (Some large-capacity band-saws have a third wheel below.) Tires on the wheels cushion and help protect the blade.

Adjusting the upper wheel controls blade tension and tracking. The tensioning control (see inset photo) raises and lowers the wheel; a tracking control on the back of the saw—often called the tilt knob —tilts the wheel ever so slightly, causing the blade to move slightly from side to side on the wheel.

Upper and lower blade-guide assemblies limit the blade's travel from side to side. Each assembly controls lateral movement with a set of guide blocks; thrust bearings limit rearward travel when you push a piece of wood into the blade.

Table-lock knobs help you tilt the table to any angle between
