8-2 Let’s look at how to make a simple square box. When you
assemble the finished pieces with the faces properly oriented, any
one of the pin ends will fit any one of the tail ends. In fact, the
box can be put together in six different ways …each of the four
corners will fit two ways!
8-3 Make five identical boards

⁄4"x 5
1
⁄2"[20x140mm] about
8"[200mm] long. Mark the inside faces of the two tail boards and
outside faces of the three pin boards (you may not need one of the pin
boards). Use Leigh e7 or

- No. 80-8
1
⁄2"[12,7mm] x 8° dovetail bit and
- No.140-8
