THE TABLE GREW UP IN THE BOOKCASE

Since the story of the design and manufacturing of two pieces of furniture: shelves and coffee table, I note that these needs (and even necessary) things that we have in the house are next to each other and together as a small Suite of furniture. All because they are made of the same materials (or rather their remnants), the same pattern and, most importantly, in the same style.

You do not want to Preface the narrative edification, but, starting to manufacture, it is necessary to understand that the shelf is not a shelf in the garage and the quality of the furniture for the house should be at the level of industrial samples. Otherwise you’ll have not only to contemplate his creation, but also to blush in front of home and especially in front of guests for all admitted flaws.

The story will lead from the shelf as the subject more complicated to manufacture, although the “warm-up” started with a coffee table (that and all the advice).

The Foundation of shelves that’s four racks, material for which was pine boards rankings with a width of 90 mm and a length of the entire height of the wall units is 1800 mm. stand Height was selected on the basis of ease of access adult members of the family to literature, lying on the very top shelf without a stand in the form of a stool or chair.

The upper ends of the uprights all have the rounded, folded blank into the package, handled jointer their longitudinal edges and equalized in length. Have a pair of rear pillars at the bottom in one corner still drank sectors of the same radius as the height of the baseboards in the place determined for shelves Then otfugovat both sides and edges of each rack and laid them before the time aside.

After that started manufacturing the shelves. Material for them was the remains sanitized (lined both sides of the race a polymeric film with a texture “pine”) chipboard thickness of 16 mm. trim bought in DIY store.

Suddenly the question arose: whether to install the shelf on the shelf at the same distance from each other (as is done traditionally) – because books that are different sizes and yet there is a binder magazines. And unless they have a place in this open step-lager? Well here will look and vase with flowers, and oversized stuffed toy, and large size figurine. Decided and the gaps between the shelves to do a variety.

All the shelves except one — upper, the same. They have sizes 400×350 mm. Top shelf — 400x 400 mm. Looking ahead, I note that the extra 50 mm was not redundant. Ledge shelf makes this different from the rest, defining the role of cap, and gives the bookcase a finished look. Speakers the front corners of the top shelf rounded with a radius of 50 mm.

The next problem that had to be addressed. is the finishing of the edges of the shelves. Suitable texture utovich edged ribbons are not found at home or in stores. Then decided to use the “ennobling” a film from scraps. However, just detach it from chipboard. Therefore, cropping soak overnight in water, and the next day easily separated the film from the swollen hardboard. Now, cut out from the film 20-mm strips, covered their rear is quite “fat” layer of polyvinyl acetate (PVA) glue, which dried with a hot hair dryer (one dryer no, you can just leave for a day or two in a warm room). Next, put strips on the edges, and smoothed using a blank sheet of paper with a hot iron. Trimmed only the front side visible (between the uprights) edges of the shelves. The back and invisible parts coated with fast drying paint. But this is done more for reassurance: many people think that exposed particle Board is isolated from the binder resin is harmful to a living organism phenol. However, this is not felt, and the invisible edges produced by the furniture industry has long been nothing not covered.

Options Assembly design was two. First — has long been mastered and proven, though relatively time consuming – on the furniture corners with screws and threaded bushes. By the way, this option had all the necessary fixtures. But in such an open furniture, like a bookshelf, corners threatened constantly eyesore. The second option is more modern, so-called screw evrotekh with the trade name “confirmat”. It promised ease of Assembly and the practical invisibility of fasteners, and therefore a more attractive appearance. And if the latter quality was apparent, the first did not come immediately — it took a GAK to say, the process of development, and without an assistant it was difficult to do. In addition, for the preparation of the holes in the two parts for each node required a threefold tool change in the electric hand drill, two drill bits (different diameters) and a countersink bit.

Bookcase:

1 — rack (pine Board s20 4 pieces); 2 — shelves (laminated chipboard s16, 5 PCs); 3 — cover (laminated chipboard, s 16); 4 — screw coupler (32 pieces); 5 — thrust bearing (nylon, 4 PCs); 6 — rear panel (laminated MDF); 7 — fastening of the rear wall (screw 3×20, on demand)

Here I note that in the journal “modelist-Konstruktor” No. 6 in 2003 was the publication of the application for the furniture Assembly of helical ties. It was given and some useful technological advice. However, one of them. where consulted to drill a hole in the pull details with a diameter greater than the diameter of the depressions of the screw was in doubt, because it’s obviously weakens the connection! Decided to check and drill the hole minimum diameter. But when screwing the screw coupler hook rasper hole that the stove in this place cracked. Then the hole diameter is slightly increased, but the result did not change until I brought the hole diameter to the recommended. For clarity and bring the drawing turnbuckle from the mentioned publication it is not every interested reader will be this issue at hand.

By the way, in the same article and drawing a special drill bit, simplifying and unifying the technological operations for the preparation of the holes in the joined parts, which is useful for those who want to develop such an Assembly as craft.

Finishing pine stands common: first, remove scratches and hitch medium-grained emery paper, then polishing with fine paper. Lacquer coating double — layer. The first layer is a hot impregnation.

The Assembly of the product when no fixtures or bench is good to make together. In the attachment of racks and shelves, preparing holes for pentavia ties. For each tie will have to first drill holes with a diameter of 5.6 mm: end-to-end in racks and at a depth of 40 mm in the shelves. Then in the shelf slightly razzenkovku it at the entrance, and the rack to drill out hole to 7 mm and razzenkovku from the front side.

Coffee table:

1 — leg (pine gloss s20, 4 pieces); 2 — top worktop (laminated chipboard s16); 3 — lower worktop (laminated chipboard s16); 4 — screw coupler (16 PCs.), 5 — bearing (polystyrene, 4 PCs.)

The node connecting the racks and shelves:

1 — screw coupler; 2 —stand; 3 — shelf

Top and bottom flange bonded with each stand two screw cable ties — to secure the rigidity and load distribution, Other (intermediate) shelf — only one tie.

Later I found a suitable sheet of fiberboard (hardboard), is also facing texture under the “pine”, and made it the back wall — it has significantly increased the rigidity of products, but most importantly — became an obstacle for sliding and falling the shelves of pens, pencils and other small items.

In conclusion, under the heel of each stand is planted and secured with a nylon bearing.

Coffee table, as noted above, made “in the image” stack. But this is only for comparison, because the table did before. Some of the differences one piece of furniture from another, there are both shelves of the coffee table (let’s call them better countertops – upper and lower) protrude from the stands (and will call them legs, as it should have stops) on both sides. The angles at the ends of the legs are rounded, and placed under the heel and attached unseemly glide, but: — fact table, in contrast to the shelves, have often to move from place to place, especially since sometimes it serves as a serving.
