Wedge Operated Jig
Move the wedge horizontally to change the height of a roller mounted at the right end of the lever. The other end of the lever can be used to work on an object.
A jig is a template or a guide that helps to automate certain tasks by controlling the motion of a tool or workpiece. The location and movement of the tool at the left end of the lever can be controlled as the wedge moves horizontally or changes angle.
