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 around and drop the teeth to rake back and forth in order to form the windrow. In some areas, a "sweep rake", which could also be a horse-drawn or tractor-mounted implement, could then be used to pick up the windrowed hay and load it onto a wagon. Later, a mechanically more complicated rake was developed, known as the "side delivery rake". This usually had a gear-driven or chain-driven reel mounted roughly at a 45-degree angle to the windrow, so the hay was gathered and pushed to one side of the rake as it moved across the field. A side delivery
