The oak buffet by Mathieu Pont skillfully combines craft furniture and designer furniture. With its drawers arranged in staggered rows and its large storage capacity, it has the advantage of being completely removable.
Cost: € 1,000
Time: 15 days
Equipment: drill, sander, router with jig and cutter for straight shanks, minicombinée (Hegner MK4), varnishing gun.
See the plan of this realization (in pdf): A removable buffet in solid oak: The plan
For a successful piece of furniture, the quality of wood and machining is crucial. If Mathieu Pont left the flow and the planing of the solid oak to a carpenter, all the assemblies (tenons, mortises, straight tails...) by against it was realized by his care, with a minicombinée with wood and the power tools. If you do not have a workshop machine, it is possible to design this buffet from planed wood. Grooves and joints can be made with a router.
To differentiate itself from conventional models assembled with tenon and mortise, our reader wanted a piece of furniture completely removable. To achieve this, he used screw-in inserts (or double-threaded nuts) and screws. cross head ". Thus, this buffet can be easily transported, even in a small vehicle. On the other hand, this solution multiplies the assemblies, by the back of the furniture, of the crosspieces and slides of drawers. Machining is therefore more difficult because they require great precision.
Mathieu Pont sought to break the monotony due to the repetition of doors and drawer fronts. With an odd number of drawers, underlined by the handles, the furniture has a dynamic line. Their staggered offset also highlights the proportion of the facade of 161 on 94cm; a ratio of 1,713 close to the square root of the number 3 (1,732). Our reader admits to having fumbled, but unwittingly found one of the subtle and harmonious proportions used by designers: the square roots of prime numbers.
The choice of a noble wood
For craft furniture, oak is used because of its longevity. However, this essence contains tannin that can produce brown spots on the wood. They sometimes appear by reaction to an alkaline product such as limestone water. To remedy this phenomenon, there is a radical solution: to react the wood on all its surface, with a mixture of water and lime (a handful diluted in a bucket is enough). It remains to sand and protect the wood with a finishing product. In the end, the appearance is darker, more "rustic But changes over time with more regularity. Another solution, chosen by our reader: multiply layers of waterproof varnish to ensure maximum protection.
Oak wood planed according to flow card, plywood veneered oak thick. 8mm (approx. 1,5m²), 8 beech racks, 7 stainless steel shell handles, 8 x 8 * 45 mechanical screws with washers, 8 x 8mm inner screw inserts, 4 x 20 wood screws, 4 x 50, 5 x 60mm, 4 push latches, 8 invisible hinges without brake, transparent matt varnish in aqueous phase
The oak blades are grooved with a router equipped with a cutter (thickness 10mm). The grooves of the slats receive false tabs of 10 x 20mm section to form the panels. The grooved sleepers are equipped with 22mm panels with a peripheral rebate.
Stagger the grooves
The grooves of the sleepers are shifted to the outer face to make room for mortises false studs (or pigeons), machined in a false tongue. Beforehand, the corners are rounded to the router or hand plane.
Fix the wedges
Inserts are glued flat on the inner faces of the sleepers. Breakthroughs, they are equipped with screws tocross head "Equipped with washers, which are anchored in screw inserts, installed in the uprights.
Mount drawers: precision work
Mechanical screws are placed on the back of the drawers as an adjustable stop. The notch provides access to the screw head to adjust the depth of the stop.
Fit slides and sleepers
The guide slides have a cross member equipped with lateral cleats. The assembly is done by pigeon or double trunnion and a screw completes the fixing.
Assemble the drawers
The sides of the drawers are assembled with a straight shank (straight milling cutter). The inner side of the sides is grooved to integrate the bottom of plywood 8mm.
Lay the facades
The drawer fronts are adjusted in the front of the buffet, leaving a peripheral clearance of 1 to 2mm. Their final installation, by screwing and gluing, is carried out after the adjustment and the setting up of the drawers on the slides.
Before mounting the added facades, grooves are machined on the sides of the drawers at the location of the slides. To avoid splinters of wood at the end of the pass, a martyr wedge is placed at the output of the tool.
The buffet is completely assembled in white (without glue) to control the good assembly of the different parts. The handles shells of drawers are put in place inbowls Machined in the center of the reported facades.
Finishes and interior fittings
The shelves are supported by classic beech racks and trapezoid cleats. They are nailed to the sides of the cabinet with fine points with a human head. The shelves are adjusted by notching in the corners.
The doors, frameless, consist of solid wood panels butted. To prevent the wood from "tiling", cleats are embedded across the wire on the inside.
Authorized by the use of push latch, the installation of invisible hinges preserves the furniture line. Their assembly requires the installation of shims placed behind the central upright and on the sides.
To varnish and to shred
All the parts are protected by 6 layers of matt varnish in aqueous phase. It is spray applied to obtain thin layers. Between each pass, 400 grit sandpaper ginning is essential for an impeccable end result.
Buffet: the final result
Straight tail or dovetail?
The same template for ripper allows to realize these two types of assembly, determined only by the strawberry used. The right groove cutter can indeed be replaced by a tapered "dovetail" cutter that provides a self-tightening assembly that requires no bonding.
In this embodiment, the rear panel may work and cause a slight displacement of the anchor points of the sleepers, hindering the handling of the drawers. It is preferable to assemble the drawers in rear crosspieces arranged symmetrically to those on the front. In this configuration, they are located under the drawers, which allows the addition of a cleat to laterally guide the drawer. This traditional technique avoids grooving the sides of the drawers and doubling their facade. It is also less sensitive to the natural wear of wood due to friction.
