Using this device you can glue wood panels different sizes. The clamp itself is easy to use and has a fairly simple design. In the presence of necessary materials making such a clamp for a home workshop will not be difficult.
For the manufacture of homemade clamps(they are also called weims) you will need a stud with M10 nuts, a 20 mm steel strip and two rectangular profile pipes with sides 40x20 mm, 80 cm long. These materials can be bought inexpensively at a hardware store.
Clamps for gluing panels: stages of work
On profile pipes We make markings and drill through holes every 15 cm, using a regular or stepped drill. We cut the steel strip with a grinder into pieces 150 mm long. In these plates we drill two holes of the required diameter.
We connect the profile pipes to each other using plates. You will also need stops - movable square shape and a fixed T-shaped one, welded from a profile with side dimensions of 20x20 mm. We screw a pin of suitable length into the movable clamp.
Features of using a clamp
It is good because when gluing wooden panels it clamps the workpiece on four sides in two planes. Thus, the gluing is of very high quality. By rearranging the T-shaped fixed stop, you can adjust the length. Watch the video on our website for the process of assembling a clamp for gluing wooden panels.
Over the hundreds of years that people have been processing wood and making various products from it, it seems that the craftsmen have tried all possible tools and devices. Meanwhile, the creation of all kinds of devices continues to this day. It is likely that all this was already invented by someone in past years, but each master tries to make devices that are suitable for him.
Wooden picture or photo frames are compressed when gluing, probably hundreds in various ways. I myself can offhand offer at least a dozen options; here is one of the devices for this work from White Myers, Workbench website.
Tape ties are most often used for compression when gluing square or rectangular products. Such as chairs, stools, boxes and small tables. The use of this mechanism is convenient because you can compress the entire product at once by applying glue and assembling the legs, drawers and legs of the chair. But when gluing wooden frames, a tape tie in its usual form is not suitable. The fact is that during compression it is impossible to maintain angles exactly 90*, due to uneven contraction.
In order to use a tape tie when assembling frames, you need to make four corner blocks. The blocks have an outer rounded edge, which helps to compress the product evenly and sawn internal corner, exactly under 90*. It is imperative to drill a hole at the starting point of the corner to prevent the frame from sticking to the blocks. More options for frame clamps in the article.
Small parts clamp
Every craftsman who works with wood uses for processing parts grinding discs And grinding drums. Sometimes you have to process a large number of small wooden parts. It can be difficult to hold them in your hand, and there is a risk of catching the drum with your hands.
To make the clamp you will need two wooden blocks 150-200 mm long. and cross section 30/15 mm. . The bars can be made by sawing a round piece with a diameter of 30 mm into two parts. . Holes are drilled in the center of the bars for a clamping bolt with a wing and several washers.
During operation, the required gap between the platforms is immediately established, and compression is carried out using a wooden wedge in the tail section. The process is quick and simple: insert the part, push in the wedge and work. We take out the wedge, change the part and again clamp it with the wedge.
Auxiliary devices for gluing wood products
The use of wood glue is mandatory for most joints used during the manufacture of various wood products. The connection must dry under force, and the amount of force can be created and adjusted using special devices. The most widespread are clamps and clamps; they can be purchased ready-made or made independently. The second option, in our deep conviction, is preferable. Why? Firstly, something received “almost for nothing” is always much nicer for us than something bought in a store for relatively more money. Secondly, during manufacturing you can take into account your own needs to the maximum extent; in a store it is very difficult to choose the desired option.

How to make wooden clamps
Clamps are very often used during the manufacture of individual small furniture parts. The advantages include ease of use and manufacture, reliability of fixation and small sizes. The disadvantages include the inability to work with parts that have large linear dimensions. This is especially true for clamps industrial production, it is very difficult to find large clamps; they are only available in large specialized stores. And there are such stores in big cities, but many craftsmen do not have the opportunity to often travel to the city in search of the right tools and accessories.
The solution is to make a clamp yourself, especially since the matter is not so complicated. To make it you will need several blocks or slats of wood hard rocks And minimum set carpentry tools.
The thickness of the bar is within 30 mm, the thickness of the slats is within 10 mm. Cut out the front stop of the clamp in the form of a hammer, a clamping element and a device for fastening the screw handle from the block. Make a ruler from a thin strip, firmly connect the front stop to the ruler into a tongue/groove, be sure to use wood glue. The other two parts should have holes in which the ruler can easily move. As a clamping device, you can use any metal bolt of a suitable diameter with a large thread. The larger the thread and the longer the thread section in the screw stop, the greater the force that can be created when clamping parts.
Exists great amount various types clamps, we settled on the simplest and most reliable. Other special clamps should be manufactured only by those specialists who are engaged in production large quantity identical products. Then you need to have special clamps for clamping corner connections"mustache" and ordinary ones, for clamping very small elements of wooden structures, etc. For most craftsmen, it is enough to have simple clamps, they can be used to make most carpentry joints.
How to make weims
Vyma is a device in which you can make glued joints on large areas. They are used during the manufacture of windows and doors, furniture panels and other products with large overall dimensions. Industrial wires are quite practical, but they are not always available, and the price of these devices may scare off some consumers. We will tell you how to make a rim from metal and wood.
Simple metal wedge
You will need a corner measuring at least 50x50 mm, several bolts and threaded stops. A frame is made from the angle, drill holes on it symmetrically at regular intervals, stops will be fixed in these holes to adjust the length of the parts to be glued. The picture shows how to weld metal screw clamps. We used standard ones, but you can use large bolts with permanently welded nuts. To increase stability to the guides, you need to weld the footrests, make them from scraps of corner. The principle of operation is very simple - after installing the part to be glued using wrench you need to tighten the bolts. Don't forget to put between wooden product and metal gasket stops.
The advantage of such a clamp is that you can clamp different sizes wooden structures. The disadvantage is the unevenness of the pressure along the length. You need to make several pieces or use very strong and rigid gaskets in the form of metal channels or I-beams.
Wooden wedge
Even more simple design, it can be made in just a few hours from waste lumber. Manufacturing material - wooden blocks 50×80 mm, length depends on the expected length of the elements to be glued. Select the number of bars taking into account the width of the products; the distance between the bars should not be more than 20 centimeters. The figure shows the manufacturing diagram; we will only describe some of the features of using a homemade wooden wedge.
There are two options for clamping the product: metal screws or wooden wedges. In order to use the first option, you need to find or purchase metal screws separately, but we do not recommend bothering with it. Clamping works well with wooden wedges. To do this, you need to prepare them first; during manufacturing, do not make the wedge angle very large - it will be difficult to hammer in and the risk of the clamps spontaneously falling out will increase.
Insert the part into the made fixture, using slats or boards of various widths, first reduce the gap between the part and the top strip of the wedge. Drive wedges into the small gap formed between them. If you wish, you can slightly improve the device we offer. To do this, you should vertical racks drill through holes at regular intervals, they will make it possible to automatically adjust the gap between the workpiece and the upper horizontal bar, the wedges will be easier to select, and the fixation will be more stable. Another, simplest, clamping method is to use rubber bands and wrap them around the parts with tension.

This device allows you to securely fix wooden blocks after spreading with glue.
To make a clamp I needed:
- 10 mm plywood,
- M10 studs and 1 meter long,
- wing nuts,
- washers,
- glue "Moment-joiner".
Making a clamp
First I made four corners from plywood. I cut out 12 squares measuring 100 x 100 mm. I made a cut of 60 X 60 mm for eight squares, and then glued three pieces together, 2 sawn to one piece.
Then I drilled two holes in each corner:
The first through with a diameter of 10 mm. To prevent the drill from moving to the side when drilling, drill from both sides.
The second is blind at 60 mm with a diameter of 8.5 mm. I made a thread in it with an M10 tap, and then screwed in a pin with glue. It turned out that in each corner one pin goes right through, and the second is tightly fixed.
Making a clamp for gluing photo frames with your own hands.
Initially, I wanted to saw off the studs, since the design turned out to be cumbersome, but then I decided to leave it in case I needed to make a frame measuring meter X meter.
Testing and modification of the clamp
Tests have shown that the frames stick together normally, but there is one drawback: When dry, excess glue remains at the bottom of the corners. Therefore, the frames were skewed. To eliminate this drawback, I made holes on the bottom side of each corner using a Forstner drill to remove the remaining glue.
Modification of a clamp for gluing photo frames using a Forstner drill.
As a result, I eliminated the distortion of the frames, and the results were good.
Any frame - large or small - has a “strict” design: it places serious demands on the squareness of the corners and their careful execution and connection. To simplify production and obtain high-quality frames with less labor, the French magazine System D offers two simple and convenient devices, which you can make yourself: a tablet for sawing bars or baguettes and a press for gluing workpieces.
Angle - not by eye
When making frame blanks, the most difficult thing is to cut them strictly at an angle of 45°. The tablet is designed to help, which will serve as a good addition to a small circular saw or a jigsaw and will replace the traditional device - a miter box, which is used when working with a hand hacksaw.
The tablet consists of a small wooden shield– a base and two thrust slats installed strictly at an angle of 90° to each other. The base of the tablet is a hardwood board with a thickness of 25 mm and dimensions of approximately 400x250 mm. Instead, furniture board or chipboard can be used.
A small cut is made on one side of the base - a gap into which the saw blade or jigsaw blade. On both sides of the cut, with an indentation equal to its width, two thrust bars are attached, the opposite ends of which are sawed off strictly at an angle of 45°. That's the whole tablet device. It is convenient to use it on a saw table, on which two parallel grooves are milled for this purpose, and two corresponding guides are attached to the bottom of the table. Thanks to them, the tablet can slide with slight friction along the guide grooves, strictly maintaining the direction of its feeding.
1 - base; 2 - guides; 3 – cut; 4 – thrust bars; 5 - screws
1 - tie with holes; 2 — locking square; 3 - protective gasket
The picture shows how the tablet with the frame blank is installed and how it is fed for sawing when the tablet moves along the guide grooves towards the saw.
In order to cut a baguette onto one side of the frame, you need to mark it inner dimensions pencil. The baguette is then pressed (from the outside) against the corresponding stop block so that the length mark is opposite the slot. Now, when the tablet moves towards the saw blade, the baguette is cut at an angle of 45° automatically. The ends of all other slats forming the frame are cut in the same way.
Gluing press
However, preparing the frame parts is still half the battle. The next task is to securely glue them together. A very simple press for assembling them will help out here. It consists of four ties - wooden slats made of hard wood with a cross section of 30x30 mm, with holes drilled in them with a diameter of 4 mm. The couplers are connected in pairs with each other using a loop - a connecting bar with dimensions of 100x30x30 mm and bolts and nuts (flush). In addition to the ties, four fixing angles are made. They are cut from hardwood blocks 30 mm thick. Each clamp has a spike at the bottom - a screwed-in screw with a diameter of 4 mm, with a cut off head.
1 — couplers (perforated slats); 2 - connecting loop; 3 — clamping angles; 4 - clamp
In order to activate the press, the couplers are placed on flat surface(table) in the form of the letter X. Depending on the size of the frame, clamps are inserted into the corresponding holes of the ties. All that remains is to apply glue to the joints of the baguette slats to be joined “on the miter” and place them in the clamps. Now you only need one single clamp. With its help, the connecting bars of the ties are pulled together, and therefore the baguette ends in the clamps, ensuring their tight connection and holding them in the desired position until the glue sets.
