Setting The Bevel. To set the bevel at a miter (an angle of 450), place the beam against one leg of the square and adjust the blade so that it will agree with equal distances on both legs, as 4" and 4", Fig. 39. Any distance may be taken, but it must be the same on both legs.

The carpenter frequently describes an angle to which the bevel may be set as "1 in 2" or "1 in 4," by which is meant that while the beam is applied, as shown by Fig. 39, the blade corresponds to the 1" mark on one leg, and the 2" mark on the other; or to the 1" mark on one leg, and the 4" mark on the other.
