Fig. 203 illustrates the common tee bevel. In this style the blade is held in position by the thumb screw at the end of the handle. The screw on which the blade slides sometimes requires adjusting in order that the thumb screw may hold properly. While adjusting the blade it should be just loose enough to move freely but not so loose that it will move without some force.

There are many ways of determining the angle at which to set the blade. Probably the best method for the inexperienced is to first draw a line of the required angle as in Fig. 116. Another method is to set the blade by the carpenter's steel square by laying the head against one edge and, for a square miter, adjusting the blade until its edge is equally distant from the corner of the square on both the body and the tongue. The head may be placed as shown in Fig. 204A or 204B. You may have at hand the triangles used in drafting. These are excellent standards for use in setting the tee bevel to any of the angles found on them.

There are many other ways of get-ting angles and setting the tee bevel, but the above will be found sufficient for all ordinary work. After the blade has been set at the desired angle it is used very much as the try-square is used as shown in Figs. 19. 20, 32, 33.
