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 by allowing a lower gear to keep the engine in the desired rev range. The importance of this is to avoid delay between the driver accelerating after the corner and when the car responds. This is especially true in turbocharged cars where not only is it important to maintain the required rev range for strong positive boost, but the 'blipping' of the accelerator can also be used to maintain turbine speeds and thus avoid turbo lag. This technique ensures that maximum power can be reached the instant the brake pedal is released and the accelerator fully depressed. Rowing is the
