Abstract
Present invention teaches a height adjustable rest having four main parts: a base, a cylindrical knob, a cylindrical post and a snap ring. The cylindrical post has a vertical straight groove to guide the up-and-down height adjustment when the knob is turned relative to the base. The base holes and the knob holes, along with the corresponding rods, provide increased torque when larger and/or heavier workpiece is being supported. The matching inner thread portion (on the inside of the cylindrical knob) and the outer thread portion (on the outside of the base) is a desired feature to make the product less susceptible to damages or work debris compared to other products with exposed threads.
