Sawfiler Variations include face angle, face length, back angle, gullet width and depth, and a frost notch (if necessary). Typical bandsaw tooth dimensions are 1-3/4" tooth space x 3/4" gullet depth x 3/4" gullet width (grinding wheel width) x 30deg face angle x 16deg back angle. Fitting means tooth dressing and involves swaging, shaping, gauging, and grinding. The tip of the saw tooth is swaged to a flare, then the sides are compressed in slightly with a shaper tool to an exact kerf. Then a final grinding pass is made. The usual gauged tolerance is +/- .005" in kerf, and <
Heel-and-toe enough to cause loss of traction if it occurs after the turn has begun. Sporting vehicles are usually modified (if necessary) so that the heights of the brake and accelerator pedals are closely matched when the brake is sufficiently depressed, and the pedals are not too far apart to permit easy use of heel-and-toe. The name stems from pre-WW2 vehicles where the accelerator pedal was in the centre (between the clutch on the left and the foot brake to the right). The brake was able to be operated with the heel whilst the accelerator pedal could be simultaneously pressed with
