ABSTRACT:
A gauge assembly for checking the alignment of radial arm saw blades relative to the saw table includes a base engageable within the saw fence guide slot with a vertical post extending upwardly from the base. A support arm is frictionally held upon the post for vertical sliding movement therealong and supports an indicator pointer pivoted to the support arm intermediate the ends of the pointer. One end of the pointer registers against an indicating plate or dial and the other end is provided with a saw blade contacting portion which is adjustable for contact with the blade surface. The gauge assembly can be used to check the perpendicular positioning of the blade relative to the table and the fore and aft parallel relationship of the blade to the table when the blade is vertical. It can also check the horizontal parallelism of the blade with respect to the surface of the table when the blade is turned horizontally.
