So my french doors have arrived. They are bifold doors, but they use a track. We don't plan on using the track, and i want to install traditional hinges. The door frame/jamb is new and oak so i need to recess the hinges for the door and the jamb. What is the best jig for a router to do this on both the door and jamb? I assume if you use square hinges that you just chisel out the small radius from the router to make it square. I don't really want to attempt to chisel out the entire hinge area , i'd rather rout it out.
