ABSTRACT:
A hinge jig having three longitudinal members and two transverse members all relatively adjustable to the each other with respect to angle and distance. Stop flanges delineate the outer limits for movement of the router bit when cutting a door hinge. The router base is rested directly onto the planar surfaces of the longitudinal and transverse members, which are adjusted to the particular size and shape cut-out desired. The jig can be adjusted to define cut-outs having other than right angles.
