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 should dry out under force, and it is possible to create and regulate the amount of force 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, always a thing received "almost for free" is much nicer for us than one bought in a store for relatively big money. Secondly, during manufacturing, you can take into account your own needs to the maximum extent; it is very difficult to find the desired option in the store.

How to make wooden clamps

Clamps are very often used during the manufacture of individual small pieces of furniture. The advantages include ease of use and manufacture, reliability of fixation and small size. The disadvantages include the inability to work with parts that have large linear dimensions. This is especially true for industrial clamps, it is very difficult to find large clamps, they are available only in large specialized stores. And there are such shops in big cities, but many craftsmen do not have the opportunity to often travel to the city in search of the necessary tools and accessories.

The way out is to make the clamp yourself, especially since this is not so difficult. To craft, you will need a few hardwood blocks or slats and a minimal set of joinery 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 a clamp in the form of a hammer, a clamping element and a device for attaching a screw handle from a bar. Make a ruler from a thin strip, firmly connect the front stop to the ruler in a tenon / groove, be sure to use wood glue. The other two parts should have holes in which the ruler will move easily. Any metal bolt of suitable diameter with a coarse thread can be used as a clamping device. The larger the thread and the longer the thread section in the screw stop, the more force can be generated during clamping of the parts.

There are a huge number of different types of clamps, we settled on the most simple and very reliable. It is only necessary to make other special clamps for those specialists who are engaged in the production of a large number of identical products. Then you need to have special clamps for clamping corner joints on the "mustache" and ordinary, for clamping very small elements of wooden structures, etc. For most craftsmen, it is enough to have simple clamps, with their help you can make most joinery joints.

How to make clamps

Vayma is a device in which glued joints can be made over large areas. They are used in the manufacture of windows and doors, furniture boards and other products with large dimensions. Industrial clamps are quite practical, but they can not always be found and, for the price, these devices can scare off some consumers. We will tell you how to make a clamp from metal and wood.

Plain metal clamp

You will need a corner of at least 50 × 50 mm, a few bolts and threaded stops. A frame is made from the corner, on it, symmetrically at regular intervals, drill holes, 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 bolts, but you can use large bolts with fixed welded nuts. To increase the resistance to the guides, you need to weld the footrests, make them from corner pieces. The principle of operation is very simple - after installing the part to be glued with a wrench, you need to tighten the bolts. Do not forget to put spacers between the wooden product and the metal stops.

The advantage of such a clamp is that you can clamp wooden structures of various sizes. The disadvantage is the unevenness of the clamp 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.

Wood clamp

An even simpler design, it can be made in just a few hours from lumber waste. Manufacturing material - wooden blocks 50 × 80 mm, the length depends on the expected length of the glued elements. Choose 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 a manufacturing diagram, we will only describe some of the features of using a wooden homemade clutch.

You can clamp the product in two ways: with 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 advise you to bother. The clamping is also excellent with wooden wedges. To do this, you need to pre-prepare them; during manufacturing, do not make the angle of the wedge very large - it will be difficult to hammer it in and the risk of spontaneous clamps falling out will increase.

Insert the part into the made fixture, using rails or boards of various widths, first reduce the gap between the part and the upper clamp bar. Drive wedges into the small gap formed between them. If you wish, you can slightly improve the device we offer. To do this, through holes should be drilled in vertical posts 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 pick up, the fixation will be more stable. Another, simplest, clamping method is to use rubber bands and wrap the parts with tension.
