Buy a Jig or Build One
Euro-style cup hinges consist of two parts. A mounting bracket screwed to the cabinet and a hinge arm with a cup-shaped mounting plate that attaches to a round mortise on the door. The round mortise is cut with a 35-mm Forstner bit and a special European hinge-mortise jig, which is available commercially or can be made in the shop.

BUILD ONE: Use a plywood jig and your router to cut accurate round mortises. (subscription required)Read more…
