180° HINGES WITH ROUTER-MADE GROOVES
When the width of the workpieces are too wide for a drill
bit to make the hole, use this method.Two boards compose
each hinge half. Make a half-round dado at the end of the
workpieces. When you glue the boards together, these two
dados make the hole for the hinge pin.
Step 1 - Use a router to make a half-round dado near the end of each of the four boards. Make the diameter of
the groove equal to the diameter of the hinge pin, and the depth of cut half the diameter of the hinge pin
(Fig. 48A).
Step 2 -
Insert the metal rod (long enough to stick out of both ends of the board) in one of the dados.
Step 3 -
Glue a second workpiece to the first (Fig. 48B).
Step 4 -
Repeat Steps two and three for the other half of the hinge.
Step 5 -
After the glue dries, remove the metal rod.
Step 6 -
Round over the ends of the glued boards.
Make the rest of the hinge the same as you would with the 180
