Abstract
A worktable having an adjustable height using a manual hand crank includes a table top, base section and a support leg extending between the table top and base section. One or more jacks are configured within the support leg and are adjustable in length. A bearing assembly is used for rotating the jack(s) to raise and lower the table top in relation to the base. The bearing assembly includes a shaft for rotating the jack(s) where the bearing assembly is configurable between a retracted and extended position for concealment under the table top edge when not in use. The hand crank may be enhanced so that it is optionally rotated using an electric drill or air tools.
