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 <
Hay rake earliest hay rakes were nothing more than tree branches, but wooden hand rakes with wooden teeth, similar in design to a garden rake but larger, were prevalent in the 19th and early 20th centuries, and still are used in some locations around the world. The typical early horse-drawn hay rake was a "dump rake", a wide two-wheeled implement with curved steel or iron teeth usually operated from a seat mounted over the rake with a lever-operated lifting mechanism. This rake gathered cut hay into windrows by repeated operation perpendicular to the windrow, requiring the operator to raise the rake, turn
