ABSTRACT:
A device of utility in precisely setting the angular relationship of a circular saw blade of radial bench type power saw, which includes a special protractor defined by removing adjoining segments of the linear leg and the curved leg thereof, and a modified T-square including a head piece having a curvature matching that of the curved leg of the protractor and a connected ruler blade extending radially toward the center of said protractor, said T-square being improved in that the thickness of the head piece is greater than that of the ruler blade and the location of the ruler blade is such that the blade can be located on either face and still use an upper and lower lip for sliding contact with the circular edge of the protractor, whereby two T-squares are not necessary as in my prior U.S. Pat. No. 5,632,096.
