ABSTRACT:
A folding workbench (20) comprises a top portion comprised of two parallel spaced boards (12 and 14) with an adjustable work holder (17) mountable along each board. One corner of the top has a vernier vise (16) attached thereto; the vise can grip work itself and can cooperate with the adjustable work holder for wide work or a fixed stop 80 at an adjacent corner for gripping very long work. The vise is mounted on a swivel plate (101) which has a quadrant shape and is surrounded by a groove (100) cut in the top of the bench to give unrestricted pathway to the vise's locking plate. The top is supported by two pair of legs (38 and 40), one pair at each end of the top. Each pair is hingedly attached (45) to the underside of the top, with one pair being hingedly attached at a lower position (spaced from the top) by the use of a spacer block (32) so that the legs can be folded against the top in a compact arrangement. Each pair of legs is braced by a strut (62) which has its lower end hingedly mounted to a midpoint (60) of its pair of legs and extends to the center of the underside of the top. A side platform (106) can be attached to either pair of legs rapidly and adjustably by means of a pair of brackets (108) under the platform.
