Hinge pocket jig

I created this to use with a router to cut hinge pockets on the door frame. It uses two small brads that you drive into the frame through the two small holes. The holes my need to be cleared with a drill. You still need to layout where the hing should be placed and carefully align the jig but it works pretty well I used it when I replaced my hollow core doors with solid doors and needed to add a third hinge.
