A great many tools are on the market for setting saws; some of them oniy bend the teeth and do not " set " them, that is, force the metal to the support of the tooth in its new position.

Others are liable to slip on the tooth after the pressure is applied, so there is no certainty in the distance from the point that the tooth will be bent, and consequently the teeth will not stand in line.

Others have gauges that are liable to slip; still others set the thick end of the saw (where there is a difference in thickness) more than the thin end, thus increasing the amount of set by double the difference of thickness.

Probably the greatest fault of most of these tools is that they injure the side of the tooth by cutting a fine groove or crease, where it is bent. As a result the tooth is weakened and may break at the setting or. what is more likely to occur, when the tooth is filed, the point comes off and many a workman blames his saw manufacturer for what is reallv due to the fault of a saw set which is improperly constructed. Another fault of saw sets is that the blow or pressure, as the case may be, is applied first at the point of the tooth. This being the weakest part, it first curls it, then straightens it, and sometimes breaks it. A tool producing any of these results should not be used. The Taintor Positive Saw Set was especially designed to obviate all of these defects. The teeth when set by this tool conform to the side and face of the anvil on which the setting has been done. The faces of the anvil are numbered so that any setting may be returned to, but these numbers have no reference to the number of the saw or number of teeth to the inch.

A saw should be set according to the work to be done, and not according to the number of points to the inch, in fact, the same saw might need to be set differently for different purposes. Face No. 4 of the Taintor Saw Set mav be used as a trial face for a saw for ordinary work in dry wood. Set a few teeth, then look across the face of the saw to see if the teeth have been moved the right amount. If they have not, find the anvil face that will give the desired amount of set, then complete the setting.

After filing, the teeth should be in line on both sides of the saw, and the groove should be perfectly straight when looking down the length of the saw from heel to point. These two ways of examining the setting are better than either wav alone.

This saw set may be used with the saw held in the hand or in the hand with one end resting on the bench, or in the clamp. In either case the tool will easily adjust itself to the work to be done, as all parts work in unison. If the setting is done in the clamp the teeth of the saw should be placed high enough above the edge of the clamp so that the saw set will not touch.

Work from heel to point on both sides of the saw and raise the saw set as it passes from tooth to tooth. By setting from heel to point the tool is not so likely to catch on the teeth.

In filing great care is necessary. In case one's eyes are not strong enough to see the points of the teeth clearly, glasses should be used while filing.

Carefully choose your files. They should be straight and evenly cut and straight in the handle. If too large they obstruct the view of the points of the teeth.

When filing keep the teeth of the saw regular in size. The tendency is to make those on the farther side, on the first filing, too large, the bevel misleading the eye.
