Wooden nails and pins to repair broken furniture

The crack in the supporting frame of the furniture is actually causing the need to put the compound where it was not provided – in places that were originally intended for large loads. After repair cracks broken part must be as strong as before, and capable of supporting the load; At the same time he repairs should be, if possible, invisible. Some types of fractures can be very successfully corrected with a single glue . However, since the cracked wood in many cases the dry and brittle glue enter its pores in an amount necessary to absorb after it is left on the surface it is sufficient to form a good bond. Some fractures require additional support in the form of keys or a quadrangular fastening blocks . Inserted or attached to the place of rupture, these key blocks and make the connection rigid, providing more space on the surface for the glue setting.

The keys to hide in the broken part or inserted into holes drilled from the outside; in the latter case the end of the key will be noticeable. If any item is split in two, and in the centers form part of the holes can be drilled to accommodate keys, the best option will repair hidden key . However, if the rupture occurred at a large angle or is at a point of bending this portion, it is easier to insert one or two keys on the outer side – repairs will be no less strong. The diameter of the dowel, as a rule, shall be equal to half the thickness of the repaired parts, and its length is twice the thickness, though if you want a firmer grip, key can be longer.

To repair breaks in thin flat pieces of furniture, such as infill chair back or frames sofa , used < strong> spacer . In the visible part of the binding unit to be inserted into the slot, cut out so that it overlaps the gap, but in the hidden parts, such as a steering wheel, a spacer can be installed through the gap without this slot. The thickness of the spacer should be equal to half the thickness of the broken part, and the length — approximately twice that part.

As the key and struts hold up better and last longer if they fit snug but not tight – too weakened fastening leave glue gap and divide too tight gap and may even cause the splitting of the surrounding trees. This gain must be done from hard wood and cutting along the entire length of the structure for strength and flexibility. Short keys of solid wood can be bought off the shelf; keys of any length can be cut from the keyed bar the correct diameter. Solid wood for the spacers can buy materials in warehouses or choose from solid unnecessary furniture. Sometimes you can get pieces of a suitable hardwood of the hidden parts of the broken furniture, for example glued blocks or drawer runners. In all cases where the adhesive is critical appropriate compression. The clamp must be installed so that the compressive force was perpendicular to the line break to pull the ends together, not pulling them out of alignment. Since the production of furniture strictly perpendicular angles in the 90 & deg; are not respected and tears do not always occur on the exact straight lines, you may need a certain ingenuity in the selection of a specific ways of fastening furniture for each case of repair.

G-shaped clips , for example, can be used for accommodation in the middle of the gap having a large angle, or indentation of the fastening blocks in the slot. G-clamp can also be attached to the bending portion as the anchor point for the band clamp , which goes by G-clamp to the end of the broken section perpendicular to the rupture. Herpes clamp that can not be set so that it is perpendicular to the compression exerted break, will pull the broken elements of alignment, causing this part to bend the line break. Is a second encircling clamp one end of the first clip to another part of the furniture, can be achieved bias compressive force so that after drying will be a direct connection.

The three common types of fractures of the tree

The wooden parts may occur " clean " fracture (Fig. top left). In such fracture sites, which can cause the adhesive are small. Repairs necessary to reinforce by means of a spacer or dowel. The tree may break down to form the notches (Fig. Top center). This creates a large fracture uneven surface that provides an effective adhesive bond. This type of repair becomes the equivalent of Connection " tongue and groove " . The tree which breaks through the structure (Fig. Above right), creates a long corner gap , which has a large portion of the surface, but not a lot of " teeth " for curing the adhesive. When repairing the angular gap may require strengthening the connection by adding tabs or spacers.

Drilling holes for dowels

Set the furniture (in the example described - a chair with a broken leg) to a comfortable height, the broken end up. Attach it to the bench or goats if it is unstable, and pinch the broken part in a vice, and broken ends up. If the fault " clean ", it will be enough to drill holes with a drill exactly in the center, using the keyed jig , as shown in the figure. If the shape of the fracture (fracture) or by the use of furniture keyed jig can not have these centers to determine visually. Using a small drill bit to drill in every element of pilot hole ; then drill the final drill hole exactly the same size as the key to be inserted into the hole. Clean the hole from debris generated during drilling, vacuuming or turn these elements upside down and knock out the pieces.

How to make a keyway peg

Insert the key into each of undersized keyed hole and mark them with depth (see. fig. left). Cut the key correct diameter for a tight fit of a length slightly less than the total depth of holes. Slightly bevel the ends of the dowel with a file or sandpaper and do on its sides slots for channels, which will spread the glue.

Connection elements

 

Put the glue in one hole on one end of the key; type in the key in the hole with a hammer until the very end (see. fig. right). Then put another broken item on projecting the key without glue, to check to see whether the broken ends are aligned. If not, treat one side of the key with a file or kromkoobrezayuschim knife , the elements to align. After realignment put the glue on the other end of the dowel in the hole and another on the broken ends, and then bring down the elements firmly together. Wipe off any excess glue.

Fixing clamp

 

Install the band clamp on one end of the broken section perpendicular to the fault of another, as far as possible (fig. left). If the clip can not be set strictly perpendicular, and it draws elements from the section line, set the same second clip at right angles to the first, combining a new clip from a piece of furniture, located in front of him to drag items back to the target (Fig. Right) .

Repair corner fault visible keyed

Drilling keyed holes

 

Apply PVA glue on the broken edge and squeeze the elements together using two strips of wood and two G-clamp to hold them in place. In an inconspicuous area to drill a pilot hole for the hole through the first keyed broken item, and partly through the second (at right angles to the fault). Using the pilot hole as a guide, drill a hole the same size as the key to be inserted into it. Clean the hole of chips.

How to insert the key

 

Take the key with grooves applied to it make it a little longer than the depth of the hole. Put glue in the hole and on the key; type in the key in the hole with a hammer. Remove the clamps and supports and wipe off any excess glue.

Bond bending

 

In order to create such a compression perpendicular to the fault, the fault attach about G-clamp and use it as a bracket to create compression using band clamp. Attach the band clamp so that it was by G-clamp to the end of the broken portion, blocking fault and remaining perpendicular to it. After the glue shrinkage treat protruding end tabs saw and sandpaper, so that it is flush with the surface of the broken part.

Installation of furniture

 

Set the furniture on bench or put it on the floor or the rear side of the least visible portion of the horizontal broken up. Apply glue to the broken edge and connect them together. Connect the fracture site through two G-shaped clamps (one on each side of the fracture) to secure the strip of wood, overlaps the lower side of the fault. If you want to prop up the broken part of the bottom of the second strip, as shown. Use the Combined Norma check the nest edge so that they are on opposite sides of the fault, at right angles to the length of this section.

Cut nest

 

Cut the ends of the socket on the mark to the planned depth, using the Shipov saw . You can use the chisel , holding it vertically, sloping side to the fault. Tap it with a hammer. Holding a chisel angle and sloping down, make the notches (the area between the slits) every 10 mm to a depth slightly less than the intended depth of the slot. Change the direction is reversed to remove the chips. Exactly trim the bottom of the nest: Spend a chisel on it, holding it sloped down. Smooth out the bottom of the slot with sandpaper or a file to the tree.

Mount backup

 

Cut hardwood backup firmly included in the socket, then put glue into the slot on the back side and the ends of the props. Insert it into the socket, wipe off the excess glue and without having to remove the previously installed G-shaped clamps and strip wood, tighten the backup in the slot with additional G-clamp. When the glue is dry, remove the clamps and sand the backup to make it fit exactly to the shape of the part.

 

Hidden backup on the screws

A simple amplifier (binder)

 

Identify as many hidden broken parts; If the spill is under the upholstery, remove the tack or staple the fabric and remove about 200 mm from each side of the fault, taking care not to damage it. Apply glue to the broken edge and squeeze them together band clamp, reaching from one end of the frame member to the next. Drill guide holes through the corners of the rectangle wooden thickness 6 to 12 mm, which covers the open side of the fault on the broken part. Apply this backup glue and attach it with screws. When the glue is dry, remove the clips and re-attach the fabric.
