Routing the hinge recess in the edge of a door can be downright dangerous without a jig or clamp to hold the door still, and even then you can still make a real mess of it if you aren’t legendary for your steady hands. This router jig from Trend Routing Technology quickly adjusts to the correct size, using the hinge itself as the pattern, and it provides the guidance needed for fast work with the router. It also features four cutouts for fire door hinges.
The downside: It runs $265. That’s not bad for a production floor or for a tool guy who hangs doors all the time — however it looks like I’ll be living with sloppy but thankfully hidden hinge recesses on my doors.
