270° HINGES WITH ROUTER-MADE GROOVES
This method uses two pieces of wood glued together for each
hinge-half. One of the pieces is very short.
Step 1 - Use a router to make a half-round dado near the end of a board. 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. 49B).
Round over the ends of the boards (Fig. 49C).
Step 2 -
Cut off the ends of the boards. The length of the cut-off should be twice the thickness of the board (Fig.
49D).
Step 3 -
Repeat Step 1 for the remaining longer boards.
Step 4 -
For both hinge halves, glue the short board to the long board with the metal hinge rod in the grooves and
sticking out both sides of the wood (Fig. 49E)
Step 5 -
After the glue dries, remove the metal rod.
Step 6 - Make the rest of the hinge the same as you would with the 180
