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 <
Ten and a quarter inch gauge seaside coaches. However the more growth in narrow-gauge style railways shows that fully enclosed coaches seating two adults side by side are possible and preferable for commercial railways. Ten and a quarter inch gauge Ten and a quarter inch gauge (or X scale) () is a large modelling scale, generally only used for ridable miniature railways. Model railways at this scale normally confine the scale modelling aspects to the reproduction of the locomotive and with steam locomotives the accompanying tender. Rolling stock is generally made to carry passengers or maintenance equipment and is not to scale. There are also a
