Assembly accessories in carpentry

The classic assemblies of solid wood parts are made only by cutting (sawing, scissors cuts, etc.) and gluing. However, there is increasing use of wood assembly and reinforcement accessories such as dowels and pins. The use of wood panels more or less friable put on the agenda the use of various accessories that allow to assemble quickly and firmly these materials that sometimes lend themselves badly to conventional assemblies (particle board in particular). They also make the furniture removable.

Ankles in carpentry

They are square for cabinetmaking, and round for carpentry. They serve to block the assemblies. We can very well cut the ankles in hardwood falls. The dowels are used in particular for the assembly of removable old furniture elements such as cabinets.

Cruciform pegs in carpentry

Blocking an assembly by a cruciform metal pin. This type of assembly, sometimes decried by professionals, allows the reinforcement of an elementary assembly.

Cross-shaped metal dowel

For quick assembly of small pieces of wood, metal cruciform dowels. They hammer down like nails and allow for solid assemblies without complicated cuts. They are invisible when properly placed on the pieces.

The carpentry trunnions

They are small cylinders of hard wood, with generally grooved barrel, which serve to strengthen the assemblies. Trunnions can also be made from round and smooth bars of different diameters. They are commonly used forassembly by recessing the panels. The introduction of the trunnions involves a prior drilling with a wood drill bit of suitable diameter (we also sell trunnion kits with the drill corresponding to the trunnions). The splines of the ready-to-use pins allow a better distribution of the glue when pushed into their housing.
Marking tips allow drilling holes in the two parts to be assembled in perfect alignment. These are small metal cylinders with points that are inserted into the hole drilled in the first part to be assembled, and which marks the location of the hole to be made in the second part, when it is placed in position assembly.

A depth marker on the drill bit allows drilling to the desired depth. In the absence of a marker of this type, a piece of colored tape will do the trick.

Drilling with depth mark

1. A mark placed on the drill bit allows drilling to the desired depth. Marking tips will identify the drilling to be performed on the second part to be assembled.

Trunnion joints must be glued with vinyl glue. It is necessary to immediately wipe the glue overflows.

Placing and gluing trunnions

2. After gluing, the pins will be hammered. The splined pins allow a good distribution of the glue and avoid its accumulation at the bottom of the hole.

After gluing the overflowing trunnion portion, the two pieces can be joined together. It is usually necessary to gently strike the opposite edge of the part to be assembled.

Interlocking assembly

3. If the holes were made correctly, the pins of the two pieces fit together easily and precisely.

The shelves of a storage cabinet are here assembled by trunnions.

Shelving assembly

4. The trunnions allow the assembly of the shelves of a rack cabinet. The positioning of both parts requires great precision.

Assembly blocks

Formerly reserved for factory-assembled furniture, the assembly blocks allow the assembly of the furniture panels in kit, but also of all those which you can be led to associate for different equipments. It can be blocks made of plastic or metal with screw or eccentric system that ensure both the connection of the elements together but also their clamping and blocking. These systems are particularly suitable for particle board which, as we know, hold the screws badly. Assembly blocks are available for almost any type of joint, at an angle or in the extension.
