For this tutorial we will use:

  • Width: 9.5″
  • Depth: 3.5″
  • Height 7.375″
  • Thickness(s): 0.5″ thick wood. 0.0625″ thick plexiglass and 0.125″ plywood
  • Inset: 0.125″ from front and back edges and 0.25″ deep

It is also necessary to determine the orientation of the box --- this particular case is envisioned as standing up, or hanging on a wall, more as a shadow box.

Launch Carbide Create and choose a stock size with reasonable proportions for your monitor and which is comfortably larger than all the parts involved:

It is probably also helpful to go into Document Background | Edit and set the grid spacing to and integral value of the box dimensions --- 0.125" should be fine enough:

Draw in rectangles for the top, bottom, front, back, and sides:

  • 7.375″ × 3.5″ (top/bottom)
  • 3.5″ × 9.5″ (sides)
  • 7.375″ × 9.5″ (front/back)

Rearrange and rotate the rectangles as desired:

As depicted in the video (see the stills at: ) some parts must be inset / smaller than the nominal dimension of the box to allow for joinery. This becomes clear as one draws in the pockets for the joinery.

The shadow box which we envision making will have the orientation of the boxes from the video being set on their left side as viewed above. Therefore:

  • the left side will be full depth so as to function as a stop
  • the right side will have its depth reduced to allow the front of the box to slide in place
  • the top and bottom will have dadoes for the front and back, and rabbets (rebates) for the side (please see the Glossary if unfamiliar with any of these woodworking terms.)
  • the front and back will need to be reduced in dimension to fit --- we will not be routing rabbets in them due to the thinness of the selected stock
