ABSTRACT:
The method of making an adjustable circular wedge which includes the steps of deforming a flat strip of metal by embossment to form a blank having a base side and a longitudinally extending tapering bead presenting a linear wedge surface, with the bead stopping short of the ends of the strip to define flat end portions. The end portions are bent sharply away from the base side of the blank at an angle of 90 degrees. The blank is wrapped about a cylindrical mandrel so that the base side of the strip is formed into a circular inner wall and so that the presented surface of the bead becomes a spiral outer wall to define, with the inner wall, a circular wedge. The flat end portions are then secured rigidly together by welding in face-to-face engagement to form a radially extending arm on the circular wedge for adjustment purposes. It is preferred in the bending step that the bending is along bend lines which intersect the respective ends of the bead for reinforcement of the bent corners.
