In order to get the hinges in, I super glued the hinge in place using a card scraper for spacing from the side of the case. Once I had the hinge outlined and marked using my marking knife, I knocked the hinge off the wood. Then I used my router, chisels and finally the router plane to remove the wastes. I used this same process to install the knife hinges in the wall cabinet with good result.
Cutting mortises is probably my least favorite task to perform. I’ve been trying out a new jig. I found this jig on the Fine Woodworking site. Unfortunately, a subscription is required to access it, but its a subscription I’ve found to be well worth it. You can find the video here (subscription also required).
Basically, its a big piece of squared up maple with a track to run the router fence in.
