Fig. 25 shows the student modeling a rosette, using the rest, set at right angles with the bed or parallel with the face plate. Prior to the modeling a shearing cut should be taken with the skew chisel to face off the material to an even surface.

The illustration in Fig. 26 shows the use of the dividers. The student is marking off to a uniform scale the position of the various corrugations in the rosette he is turning.

57. The Universal Saw.—The operations that can be performed on the universal saw are so many that no attempt will be made to illustrate them all here. But enough are given to show the characteristic operations involved in cross-cutting, ripping, and dadoing,—the three basic uses of a circular saw.

It is a more dangerous tool than the lathe and the guard should be kept over the saw at all times, except of course, in dadoing when it can not be used.
