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 <
The Gullet The Gullet The Gullet is a narrow channel between the eastern extremity of Adelaide Island and the west coast of Graham Land, Antarctica, separating Hansen Island and Day Island and connecting the heads of Hanusse Bay and Laubeuf Fjord. This area was first explored in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot who, though uncertain of the existence of the channel, sketched its probable position on the charts of the expedition. The channel was first visited and roughly surveyed in 1936 by the British Graham Land Expedition under John Rymill. It was resurveyed and given this descriptive name
