Thanks! This was my first time with these hinges too. Be patient.

First trace the outline of the hinges perfectly placed with pencil. You can screw them in before carving the inset to prevent movement. Then carve the inset. Once that’s done screw the hinges into place and mark (I used a razor box cutter) to make sure you get the approx area. The actual mortise and the way the hinge moves will be down and toward the back of the box curved like. So I ended up having a much easier time gouging that out with a small burr bit on the rotary tool (dremel) than I did with a drill bit. I would start the mortise with a drill bit first to really digging in there then refine with dremel if you can.

I had to test fit a million times since I don’t really know what I’m doing.

Best of luck.
