This simplified version can be built with limited tools and a basic skill level. The drawing is included in the video description. Note that the drawing units are in inches verses millimeters shown in Make Magazine.

Tools:

• Saw
• Drill & bits
• Hammer (optional)
• Sander
• Tape measure
• Pencil

Materials:

• 4 foot long 1x6
• 4 inch long 2x4
• 3/8” and 1/4” dowels
• Screws or Nails (optional)
• Glue
• Wood filler
• Paint or Stain

Refer to these images during build.

Cut bottom to 8.25” x 5.125”. Cut two sides to 8.25” x 2.75”

Cut ends as shown. Add blind hole to T-shaped end. This will be the locking feature for the top.

Cut fixed top and rotating top as shown. Note that this piece should start from the same size piece as the bottom (8.25” x 5.125”). Add thru holes as shown.

Cut slotted top as shown. Add blind 3/8” hole to end. I used a drill and wood file to make the slot.

Cut block from a 2x4. Add blind hole as shown.

Cut dowels as shown.

Attach sides and ends to the bottom piece. This can be done with glue, nails, screws, etc. I used a pocket hole jig and glue.

Add inside block and pins. The block can be attached as desired. The pins are glued into these pieces.

Attached fixed top and slotted top as shown. I used glue and wood screws from the inner side.

Assembly as shown. Insert locking pin as the final step.

I added a 3D Print version which includes design improvements.
