145. Bending or Twisting Wrench.—[Fig. 131]. This should be made from the same quality of steel of the same dimensions as the preceding tool.
Fig. 131.—Bending or Twisting Wrench.
Fig. 132.—Scroll Bending.
The bending wrench is used in connection with the bending fork for shaping a scroll, as shown in [Fig. 132]. When the wrench is placed over the material so that its jaws will grip the sides and the handle of the wrench is pulled in the direction indicated by the arrow, bending will take place at e. If the straight end of the scroll were pulled in the same direction, bending would occur at f. Sometimes when scrolls are being connected with the band, they are sprung out of place. By the use of this wrench they can be brought again into position by bending them close to where the band was put on.
These tools may be used together for twisting light material, when the vise and monkey wrench could not readily be utilized.
