Abstract:
Verification apparatus for checking the accuracy and alignment of the arbor and cutting blade of a table saw relative to the guide groove in the work supporting table of a table saw which extends transversely of the longitudinal axis of the arbor, wherein said guide groove has a bottom surface and a pair of opposed side surfaces and said arbor has a free end and a stop which is spaced from said free end, said apparatus comprising:(a) a reference plate which has a flat reference surface and an aperture for enabling the reference plate to be mounted on the arbor of a table saw, said reference surface having markings at predetermined angular intervals relative to the aperture of the reference plate; (b) a cap having a bore for enabling the cap to be mounted on the free end of an arbor of a table saw, said cap having visual indicator means located at predetermined angular intervals relative to the arbor; (c) locking means for removably fixing said cap to the free end of the arbor; (d) a compression spring for mounting on the arbor between said cap and said reference plate for biasing the reference plate against a stop on the arbor of a table saw; and (e) an alignment gauge apparatus comprising: (1) an elongated guide bar for slidable mounting in the groove of a table saw, said guide bar having a generally rectangular cross section which includes a bottom surface, a first vertical side surface and a second vertical side surface which is opposite said first vertical side surface; (2) a cross bar which is mounted on said guide bar so that said cross bar extends substantially transversely of said guide bar; and (3) a dial gauge which is mounted on one end of said cross bar, said dial gauge having a housing which contains a dial face, a dial and a feeler rod which is operatively connected to said dial, and which is slidably mounted on said housing for movement longitudinally of said cross bar, said feeler rod having a free end which extends beyond the end of said cross bar to which said dial gauge is attached.
