Finding the holes for European-style hinges isn’t particularly troublesome, especially if you take the time to make a simple jig, but the makers of the Hingemark think you can do it more quickly and accurately with their jig.
The jig has two stops that you fold down to catch the edge of the door when marking the holes for the hinges. When the jig is in position you just tap the spring-loaded punch labeled door. To mark the mating holes in the carcass you just fold the stops up, slide the jig into place, and tap the two punches labeled “cabinet.”
Hingemaker provides a video on their site, but it requires Windows Media Player (or a suitable plugin) to watch. Let me just begin loading Netscape Navigator… They need to get with the program and post a video everybody can easily watch, like this YouTube video I’m linking to from CabinetmakerFDM.
The Hingemark will cost you $30 before shipping.
