This custom creation consists of two large storage boxes closed by a single lid that forms the table top. The bottom rests on glued cleats, to reinforce the part in contact with the ground.

Use plywood

To make this piece of furniture, it is advisable to use marine grade plywood. From five folds and beyond, these panels are called "plywood". They are stronger and lighter than the medium or chipboard, which explains the difference in price with these. The resistance obtained is not only due to the quality of the material used.
The corners of the boxes are cut in miter to increase the bonding surface and hide the edge of the panels. The bonded assembly is reinforced with No. 10 lamellae (19 x 53 x 4 mm). Indeed, on panels 15 mm thick, it would not have been possible to place slats of current size No. 20 (19 x 56 x 4 mm) or another type of pigeon (domino or trunnion). A machining template has been manufactured to perform the miter cuts with all the necessary precision.

Opt for a painted finish

The rather monotonous aspect of the multiplis, here obtained from okoumé wood unrolled, can receive a satin painted finish.
The paint can be spread by brush, roller or spray gun by diluting the aqueous paint with 10% water. After the first coat of paint, the wood fibers rise up under the action of moisture. It is therefore necessary to squeeze (sanding) the extra-fine sandpaper, before passing a second or even a third layer.

Preparation of assemblies

Machine the miter cuts at the router.

  • 15 mm thick panels are dimensionally controlled before machining miter cuts to the router or ripper.

Make a machining template to cut the slots of the assembly slats.

  • To cut the slots of the assembly slats in the thickness of the miter cuts, make a machining template to back the 45° inclined piece.

Place a shim under the tool to achieve the same centering for all milling.

  • A wedge (thickness 8 mm) screwed on the template and placed under the tool allows to obtain the same centering for all millings.

Mark the centering marks of the assemblies on the table top.

  • Mark the centering marks of the assemblies on the table top and on the frame cross members.
  • The markers are spaced 10 to 15 cm apart.

Make the cuts on the frame rails of the table top.

  • Another machining jig makes it possible to vertically support the crossmembers of the tray to machine the cuts.
  • On the whole piece of furniture, the milling machine is set to install slats n° 10.

Use the machine height guide to cut the edges of the tray.

  • To cut the edges of the board, use the machine's height guide, set so that the frame rails are flush with the top.

Assembly of elements

Glue the parts to be assembled.

  • Prepare two dormant clamps in the length of the tray and some clamps for the width.
  • Glue the two parts to be assembled and introduce the strips n° 10.

Hold the panels with clamps.

  • Tighten moderately after placing shims to distribute the clamping force and avoid marking the panels with the clamps.
  • Blot off excess glue before drying.

Tighten the casing gradually.

  • Tighten the box gradually and at the same time widthwise and lengthwise, so that the ends of the miter cuts meet to form regular angles.
  • Check the squares.

Sand the panels forming a slight bevel at the top edge.

Trick
After complete drying of the glue, sand the panels forming a slight bevel at the upper edge, to facilitate the establishment of the tray on the boxes forming the base of the table.

Glue the spacers against the boxes.

  • Place the tray and the boxes upside down.
  • Paste spacers against the caissons.

Insert a strip of cardboard.

  • Insert a strip of cardboard to obtain a slight clearance and prevent overflow of glue.

Glue-nail cleats to the base of the cribs.

  • Glue-nail cleats to the base of the cribs. They serve as a support for the melamine bottom laid after finishing the plywood panels.

Sanding and finishing

Soften the edges of the tray to the router.

  • With a quarter-round pilot cutter, soften the edges of the tray to the router.
  • Avoid corners, which may cause splinters, but finish with sander.

Machine the hollow handles at the router.

  • Machine the hollow handles to the router. The cutter is guided by a template and a guide ring.
  • Sand all together with medium grain glass paper.

Apply a coat of spray paint.

  • Apply a coat of satin paint in aqueous phase, preferably with a spray gun.

Pass the second coat of paint.

  • Spread (extra fine grain) before passing the second coat of paint.
