This tool was made Alexey Vagin from Berezniki. The Soviet shelving system was used as the source material, which long years laying around in the garage.
It is represented by several long racks that were placed from floor to ceiling. The thickness of the metal is quite decent - 2 mm. The length of each profile reached 1220 mm. The pitch between the holes was 35 mm. 
Stops for the shelves were attached to them with hooks; the shelves themselves were not preserved over the years. The photo shows a shelf support with hooks. 
In the process of becoming familiar with the wisdom of carpentry, the idea was born to make a clamp from these profiles for gluing furniture panels.
In principle, everything is already ready: take it and use it, except for one thing. The holes in the profile were not along the entire length. The 330 mm ends were deprived of these holes, which significantly reduced the length of the wedge. 
I had to improve it. Given the absence of a grinder, I had to work with my head and then with a drill. Drilled several holes in a row 
and removed the jumpers between them with a washer, which he hit with a hammer. 
Not very aesthetically pleasing, but angrily, the main thing is that the stops are fixed.
To begin with, for testing, the wedge principle of clamping was used, that is, the parts were placed on the frame between the clamps that were most suitable in terms of distance. And then, using wedges, they pressed them against each other and left them to dry. 
The wedges were moved using a pistol clamp, which turned out to be a fairly convenient method. 
Subsequently, it is planned to simplify the clamping process by welding nuts into the holders into which the bolts will be screwed. By tightening the bolts, high-quality clamping will be achieved.
The design in this (wedge) configuration has already been tested. The results were considered satisfactory.
Natural wood and how construction material, and as a material for making furniture does not lose its relevance. Unfortunately, there are not many places left on the planet where trees grow, from the trunks of which one can make solid door leaves, countertops, or even wide window sill boards. Such a simple device as a wedge allows you to make glued blanks for home and garden furniture with your own hands.
Technology for the production of laminated wood panels
Even if the material (log thickness) allows for the production of wide products, their further use raises a number of questions. Things made from one piece solid wood Well, they are very capricious in operation. Those who have worked extensively with wood know very well what a “propeller board” is.
In order to wooden product solid wood has not been deformed, the material must first be thoroughly dried and, preferably, kept for at least a month in the room where it will be located. This condition is practically impossible to fulfill when we are dealing with door leaf or a window sill board - humidity, temperature changes will inevitably lead to deformation of the product.
Elements made from laminated wood do not have these disadvantages. Bars are taken from the same or different ones, assembled into a single block and glued. In order to wooden blanks become one, is used special device- vayma. With your own hands you can do it without special labor assemble a fully functional device.
A simple wema, assembled “on the knee”
Sometimes there are situations when some type of work needs to be done once. Suppose it is decided to arrange a table made of laminated spruce in the gazebo at the dacha. Does it make sense to buy expensive factory-made clamps? In such cases, a simple, in a sense disposable, wedge is made with your own hands. Drawings of the device are shown below.
In order to glue an array of blanks together once, you will need long self-tapping screws, a screwdriver, a hacksaw and a carpenter’s hatchet.
Workpieces are stacked in a row cross beams(beam every 40...45 cm). On both sides of the workpiece, parallel to it, long longitudinal beams (equal in height to the workpiece) are laid and attached to the crossbars with self-tapping screws. On top, again, the upper transverse bars are fastened with self-tapping screws. That's all the vayma, made with your own hands.
To compress the workpiece, all that remains is, as shown in the diagram, to wedge it with specially planed wooden wedges. After the product is ready, the clamp can be disassembled and the material can be used at your discretion.
Steel profile wedge
But sometimes craftsmen assemble wires no worse than factory ones. Here's one option:
The clamping screw is first unscrewed until it stops. The slats are glued and placed on the clamp, starting from the clamping unit. After the array blank has been assembled, it is covered with the top profile pipe, a mating unit is secured with bolts into one of the pairs of holes (depending on the width of the future array).
By rotating the clamping bolt, the workpiece is compressed from the sides. The design of the clamp is made in such a way that the upper and lower pipes are also strongly pressed against each other when the screw is tightened, which makes the future workpiece perfectly flat. This kind of banding, made with your own hands, allows you to make any products - from cutting boards to the door panels.

Characteristics of weims for gluing boards
Modern assembly tools wooden structures using the compression method, they are produced in a wide range of varieties, the purpose of which is determined by the type of product being created. In the serial production of frame and panel products, it is possible to buy clamps for panels, special devices for strong bonding of material using side pressure.
Machines for adhesive assembly of parts under pressure are necessary type equipment at manufacturing plants furniture facades, entrance and window groups. Uniform distribution of pressure along the plane of the package makes it possible to produce products with high performance qualities and decorative characteristics. The main purpose of the wedge for gluing panels is to create clamping force with optimal level pressure, which provides:
- no gap between joined elements;
- extremely precise position of the parts to be connected;
- clear geometric parameters of a given shape;
- dense and durable joining of elements.
Compact installations do not require a special base and occupy a minimum area of production premises, are economical to use and easy to maintain. Productive and reliable machines guarantee the production of products in full compliance with the technical requirements for laminated laminated wood. The costs of purchasing a press wire are quickly returned to the enterprise, and the increased quality of products contributes to increased sales and growth in real profits.
Operating principle of the installations
Weights for furniture panels have a fairly simple design, including units for basing, fixing and pressing a package of blanks. Stops are fixed to a stable metal frame, which serve to prevent distortions when laying the package and are made in the form of stably fixed and movable rulers. The ability to quickly change the position of the basing elements ensures rapid reconfiguration of operating parameters when working with workpieces of different sizes.
The force of hydraulic or pneumatic equipment drives the clamping elements, with the help of which the structure is assembled. The technological strength of the connection is achieved due to the force applied to the parts and exact date holding time of the package during pressing. In devices with heating elements processing time is reduced due to thermal effects on the workpiece, accelerating the glue polymerization process. Changing the pressure parameters in the system is done from the control panel.
Classification of shield wires
The capabilities of the installations are determined by the power power block, dimensions of the processed material and the presence of functions that allow you to set the most effective operating mode when using raw materials with specific characteristics. Each type of product corresponds to a device with design features. Weights for gluing furniture panels are divided into 3 categories according to the type of load created: 
- hydraulic;
- pneumatic;
- rotary.
The machines are produced in horizontal and vertical version, have a different number of working sections and differ in pressing force. Devices with a vertical layout take up small area and are the best option for rooms with cramped conditions. Equipment with hydraulic system characterized by increased power and the ability to produce smooth and uniform pressure on the surface of the batch workpiece.
Selecting a unit with optimal characteristics
Shield clamps with pneumatic drive are more suitable for use in small-scale production. Hydraulic or rotary machines have high performance and provide effective results during the continuous operation of large woodworking or furniture enterprises. If it is necessary to glue workpieces with large dimensions, it is possible to combine several modules to increase the working length of the equipment.
When choosing a clamp for gluing timber or making panel structures should be considered specifications settings that affect the functionality and performance of the device:
- dimensions of products proposed for production;
- number of installed hydraulic cylinders or pneumatic chambers;
- indicators of the total pressure on the surface of the workpiece.
For large production volumes, a machine with a double-sided design, which has independent working zones for simultaneous processing of material, allows you to increase the speed of the process. Depending on the model, the assembly table design is made in a stationary design or is available with wheeled carriages, which allow convenient movement of prepared parts when loading and unloading a package.
