Why make it complicated when it can be simple? This is probably what Serge Laurence said by making this child's desk. With few means and simple solutions, he came up with an interesting result. This piece of furniture can be transformed perfectly into a side table for a telephone corner.
Realization: 2 to 3 weekends
Cost: 80 euros
Mini equipment: Circular and jumping saws, ripper, vibrating drill or orbital drill.

To make this desk, Serge Laurence has not machined tenons or mortises: the assemblies use trunnions and lamellae. And the materials chosen are commonly available: planed pine, glued pine panels, 5 mm plywood. Heavy equipment is not necessary (like a planer-jointer), the electro-portable is enough. With a nice stained finish, the trick is played.
This pretty piece of furniture consists of two elements: the office itself, and its enhancement. It has two identical trays, whose front edge is rounded half-moon. Three partitions intersect the volume between the trays in two lockers, closed at the back by two independent funds.
■ The central partition is longer to follow the rounded shape. The partitions and trays are in laminated pine, and the plywood bottoms (preferably pine plywood).
■ The set is placed on a solid pine base. The four legs are connected by seven sleepers, forming two belts. The upper belt is flush with the top of the feet, just below the lower plate. The lower belt runs 25 cm above the ground and does not have a front cross member. Its side rails are surmounted by two glue-laminated shelves.
■ Notched to fit between the feet, these shelves have their outer corners rounded to a radius of 12.5 cm. Feet and crosses are decorated with moldings on leave, stopped at 40 mm from the ends of the pieces and assemblies.
■ The riser is entirely made of glulam except for its plywood bottoms. It consists essentially of two shelves and two cheeks that connect them to the office. The upper faces of the shelves are respectively arranged at 338 mm and 456 mm from the upper tray of the office.
■ A bottom closes the volume at the back, between the desk and the lower rack. Chanted in the shape of a very flattened policeman's hat, a bandage runs from one cheek to the other above the upper rack. A floral motif, engraved with the router, adorns the cheeks and the headband.
■ The space between the shelves of the riser is divided into three by two intermediate partitions. The central volume thus delimited is a locker, closed at the back by a bottom. The two side volumes are occupied by two small drawers. These are composed of two sides and a back assembled by 45° chamfer, a facade abutting the sides, and a bottom. The handles are simple semi-circular notches cut into the upper edge of the facades.
■ The drawers are wedged between slides formed of two pairs of 10 x 30 mm section battens fixed flat on and under the drawers, and two 10 x 10 mm battens ensuring lateral stalling. A small plywood key, located at the back of each drawer, avoids the excessive output of the latter, in combination with an abutment disposed on the lower shelf.
■ Given the small size of the drawers, keys and runners are not essential if there are no plans to store fragile items. While simplifying the manufacturing, their removal would allow to expand the drawers by 2 cm and use their full height of 95 mm; it would be enough to change the height of the back and sides of drawers, and the length of the first.
The author uses simple trunnions to assemble the parts of the base, and the latter to the plate, as well as lamellae to connect the laminated elements between them. These slats can be replaced by other pins if you do not have a lamelleuse. As for the plywood bottoms (furniture or drawers), they are all inserted in 5 x 5 mm grooves on all four sides, including between the desk top and the back up.
Assemble with trunnions
If the cuts are square, trunnions are sufficient to firmly assemble the base. This principle, proven in industrial manufacture, would be suitable for panels in the absence of laminator.
The ornaments of the base are machined after preparing the assemblies, but before gluing. Mark out the moldings and then work freehand at the router with a rolling mill.
Cut and sand
The glue-laminated elements are cut with a circular saw for linear plots, with a jigsaw for curves.
The cuts are then sanded, simultaneously for identical pieces.
Glue and indent the lower shelves
Only glued laminated parts of the base, the lower shelves are glued to the cross members with slats. They are indented to give way to the feet. Their edges are rounded.
Assemble the base
The base is assembled in stages, ensuring squaring: each pair of legs is assembled to the side rails (shelves included), then the whole together with the front and rear rails.
Assemble trays and grooves
The edges of the glulam panels are rounded to the router. After grooving, the trays and shelves are assembled with their respective partitions, not to mention the funds.
Report the base
After drying the glue, the base is attached under the tray. The assembly is indifferently by slats or trunnions, or even by a discrete screwing (by drowning the screws in a chambering).
Reproduce the pattern
The floral pattern (or other simple decor), cut from a template of MDF or plywood, is reproduced on the cheeks and the headband with the router equipped with a copying sleeve and a throat cutter.
Prepare the cheeks
The cheeks are prepared as trays (rounded, groove, quarter-round), then assembled at the office by inserting in the background, the block of shelves equipped with drawer slides, the headband.
Adjust the background
The assembly of the riser is put in press, making sure to squaring. The latter poses little problem: the bottom, plywood can hardly play, it is adjusted to the exact dimensions.
Assemble the drawers
The sides and the back of the drawers are assembled by 45° chamfer, which supposes precise cuts. But do not worry, it's easy to replace them with a square bracket assembly.
Equip the drawers with a stop
The drawers, mounted on wooden runners, are equipped with a stopper, simple assembly of small pieces of plywood. Such a device is almost a luxury for such small drawers!
