Convenient clamps for gluing boards made of wood. Angle Clamps Wood Frame Bonding Tools

Any frame - large or small - is a "strict" design: it makes serious demands on the squareness of the corners and their careful execution and connection. To simplify production and get high-quality frames with less labor, the French magazine System D offers two simple and convenient devices that you can make yourself: a tablet for sawing bars or a baguette and a press for gluing blanks.

Angle is out of sight

When making frame blanks, the most difficult thing is to cut them strictly at an angle of 45 °. In scrap, the tablet is designed to help, which will serve as a good addition to a small circular saw or electric jigsaw and replace the traditional fixture - a miter box, which is used when working with a hand saw.

The tablet consists of a small wooden shield - the base and two persistent rails, installed strictly at an angle of 90 ° with respect to each other. The base of the tablet is a hardwood board 25 mm thick and approximately 400 × 250 mm in size. Instead, a furniture shield or chipboard can also be used.

On one side of the base, a small cut is made - a slot into which a saw blade or jigsaw blade will pass. On both sides of the cut, indented to its width, two thrust bars are attached, the opposite ends of which are sawn 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, and two guides that respond to them are attached to the bottom of the tablet. Thanks to them, the tablet can slide with slight friction along the guide grooves, strictly maintaining the direction of its feed.

1 - base; 2 - guides; 3 - propyl; 4 - persistent bars; 5 - screws

1 - coupler with holes; 2 - angle-lock; 3 - protective gasket

The picture shows how the plate with the frame blank is installed and how it is fed for sawing when the plate moves along the guide grooves towards the saw.

In order to cut a baguette on one of the sides of the frame, you need to mark its internal dimensions with a pencil. Then the baguette is pressed (outside) against the corresponding stop bar so that the length mark is against the slot. Now, when moving the tablet towards the saw blade, the baguette is cut at an angle of 45° automatically. In the same way, the ends of all other rails that form the frame are cut off.

Gluing press

However, preparing parts of the frame 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 screeds - wooden slats made of hardwood with a section of 30 × 30 mm, with holes drilled in them with a diameter of 4 mm. The ties are connected in pairs with each other using a loop - a connecting bar with dimensions of 100x30x30 mm and bolts with nuts (solid). In addition to the ties, four fixing brackets are made. They are cut from hardwood blocks with a thickness of 30 mm. Each latch has a spike at the bottom - a screwed screw with a diameter of 4 mm, with a cut head.

1 - ties (perforated slats); 2 - connecting loop; 3 - squares-clamps; 4 - clamp

In order to actuate the press, the ties are laid on a flat surface (table) in the form of the letter X. Depending on the size of the frame, clamps are inserted into the corresponding holes in the ties. It remains to apply glue to the joints of the baguette rails to be connected "on the mustache" and lay them in the clamps. Now you need one single clamp. With its help, the connecting bars of the screeds are pulled together, and hence the baguette ends in the clamps, ensuring their tight connection and holding them in the desired position until the glue seizes.

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 under force, and it is possible to create and adjust the amount of force using special devices. Clamps and clamps are the most common, they can be purchased ready-made or made independently. The second option, in our deep conviction, is preferable. Why? Firstly, a thing that we received “almost for free” is always much nicer for us than something 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 stores in big cities, while 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 a clamp yourself, especially since this is not so difficult. For the manufacture, you will need several bars or slats of hardwood and a minimal set of carpentry tools.

The thickness of the bar is within 30 mm, the thickness of the rails is within 10 mm. Cut out from the bar the front stop of the clamp in the form of a hammer, the clamping element and the device for attaching the screw handle. Make a ruler from a thin rail, 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 easily move. As a clamping device, you can use any metal bolt of a suitable diameter with a coarse thread. The larger the thread and the longer the thread section in the screw stop, the greater the force that 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 necessary to make other special clamps only 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 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 connections.

How to make wyms

Vyma - a device in which glued joints can be made over large areas. They are used during the manufacture of windows and doors, furniture panels and other products with large overall dimensions. Industrial clamps are quite practical, but they are not always available and for the price these devices can turn off some consumers. We will tell you how to make a wyma from metal and wood.

Simple metal wedge

You will need a corner with dimensions of at least 50 × 50 mm, a few bolts and threaded stops. A frame is made from a corner, drill holes on it symmetrically at regular intervals, stops will be fixed in these holes to regulate 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 the stability of the rails, you need to weld the footboards, make them from scraps of a corner. The principle of operation is very simple - after installing the part to be glued, use a wrench to tighten the bolts. Do not forget to put gaskets between the wooden product and the metal stops.

The advantage of such a clamp is that it is possible to clamp wooden structures of various sizes. The disadvantage is the uneven clamping 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 wyma

An even simpler design, it can be made in just a few hours from lumber waste. Production material - wooden bars 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 the manufacturing scheme, we will only describe some of the features of using a home-made wooden rim.

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 separately purchase metal screws, but we do not advise you to bother. The clamp is perfectly performed with wooden wedges. To do this, you need to pre-prepare them, do not make the angle of the wedge very large during manufacture - it will be difficult to hammer it in and the risk of spontaneous loss of clamps will increase.

Insert the part into the fixture, using slats or boards of various widths, first reduce the gap between the part and the top lath of the clamp. Drive wedges into the small gap between them. If you wish, you can slightly improve the device we offer. To do this, it is necessary to drill through holes at regular intervals in vertical racks, 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, easiest, clamping method is to use rubber bands and wrap them around the parts with tension.

With this device, you can glue boards made of wood of different sizes. The clamp itself is easy to use and has a fairly simple design. With the right materials, making such a clamp for a home workshop will not be difficult.

For the manufacture of home-made clamps (they are also called clamps), you will need a stud with M10 nuts, a 20 mm steel strip and two rectangular shaped pipes with sides of 40x20 mm, 80 cm long. These materials can be bought inexpensively at a hardware store.

Clamps for gluing shields: stages of work

On profile pipes we make markings and drill through holes every 15 cm, using a conventional or stepped drill for this. We cut the steel strip with a grinder into segments 150 mm long. In these plates, we drill two holes of the desired diameter.

Profile pipes are connected to each other using plates. You will also need stops - movable square and fixed T-shaped, welded from a profile with side dimensions of 20x20 mm. We screw a hairpin of a suitable length into the movable clamp.

Features of using a clamp

It is good because, when gluing wooden shields, 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. See the video on our website for the assembly process of the clamp for gluing wooden shields.

This device allows you to securely fix wooden bars after spreading with glue.

To make a clamp, I needed:

• 10mm plywood,
• studs M10 and 1 meter long,
• wing nuts,
• washers,
• glue "Moment-joiner".

Clamp manufacturing

First, I made four corners out of plywood. I sawed out 12 squares measuring 100 X 100 mm. For eight squares, I made a cut 60 X 60 mm, and then glued three pieces, 2 sawn with one whole.

Then I drilled two holes in each corner:
The first through with a diameter of 10 mm. In order to prevent the drill from pulling to the side during drilling, I drilled from both sides.
The second is deaf at 60 mm with a diameter of 8.5 mm. I made a thread in it with an M10 tap, and then screwed the pin with glue. It turned out that in each corner one hairpin passes through, and the second is fixed tightly.

Making a clamp for gluing photo frames with your own hands.

Initially, I wanted to saw the studs, because the design turned out to be cumbersome, but then I decided to leave it, suddenly I need to make a frame measuring meter X meter.

Clamp tests and modifications

Tests have shown that the frames stick together normally, but there is one flaw: when dried, excess glue remains at the bottom of the corners. Therefore, the frames were skewed. To eliminate this shortcoming, I made holes on the underside of each corner with a Forstner drill to remove glue residue.

As a result, I eliminated the distortion of the frames, and the results were good.
