Clamps quick-clamping with your own hands. Do-it-yourself clamp facilitates the work of the master and saves him money

A clamp is a tool that allows you to fix a part during processing. Masters often use different kinds clamps at work. Whether it is a carpenter, or a metalworker, there is always a need to use it.

This device is available in different options from universal to specialized. Relatively recently, a new modification has appeared: a quick-clamp clamp. Develops compression force up to 450 kg.

The task for all types is common - to fix the workpieces for processing or connecting to each other.

Like any other tool - clamps can be purchased at the store or made independently. The second option is often chosen by professionals. It’s easier to come up with your own design than to look for an option for individual tasks.

Homemade clamps - varieties and manufacturing technologies

Angle clamp

Such devices are used to fix two objects (not necessarily of the same size) at a right angle, to connect them together in any way. These can be wooden blanks when gluing, or assembling with the help of corners and confirmation.

However, most often, an angle clamp is used as a jig for welding. metal parts at a right angle.

For manufacturing you will need:

• steel corner 40 mm, 3-4 mm thick;
• steel plates 40-50 mm wide;
• threaded studs, preferably hardened;
• bars for collars;
• nuts for the worm mechanism;
• welding machine;
• drill, taps.

We weld the corners to steel plates strictly at an angle of 90 °.

We attach a worm structure to each side by welding. This is the same corner with a welded stop nut or thickening, in which the thread is cut in accordance with the hairpin. The width of the working gap is selected for potential workpieces.

IMPORTANT! If the range of workpiece sizes is too wide, it is better to make several clamps. Too much stroke of the knob does not contribute to a strong fixation.

A stud-knob is screwed into the working nut, after which an emphasis is assembled at its end. As a rule, this is a design of two metal washers. different size. The stop should scroll freely on the hairpin.

In this article, you can familiarize yourself with detailed instruction for the manufacture of homemade wooden clamps.

This auxiliary tool will be useful for fixing any parts, for example, for processing parts or for holding tightly when gluing several parts together.

In this project, the author decided to make several clamps at once, a kind of set for fixing parts of various sizes. But you may not need that many clamps, so for simplicity, the amount of materials used will be indicated per clamp, and if you want to make exactly the same set as the author’s, then simply multiply the amount of materials by four.

Materials used:
- Hardwood timber 1.9 cm thick and at least 2.5 cm wide
- steel bar 12mm
- hairpin 6 mm 20 turns per 2.5 cm
- inch nuts 12mm 2 pcs.
- inch spring pins 2.38mm, length 19mm 2 pcs.
- tap 6 mm 20 turns by 2.5 cm for cylindrical nuts
- drill for tap 5 mm.

Description of the manufacturing process of wooden clamps:

Step one: preparing the wooden parts.

To begin with, the author decided to divide the wooden blank into two parts. The first part should be wider, clamp sponges will be made from it, measuring 25 by 19 mm. The second part of the workpiece will be square in shape with a size of 19 by 19 mm, it will be necessary to make clamp handles from it. Dividing the initial wood blank in this way will allow you to cut the necessary parts faster and easier.

Step two: Cutting out the handles for the clamp.

At this stage, a band saw was used.

In order to cut the blank for the handles to the desired shape, an angle of 33 degrees was set on the machine. A 12 mm nut was used as a separator to obtain the required thickness and shape orientation.

Thus, making cuts with the help of a machine, turning the workpiece in turn, the author cut off layer by layer, obtaining a hexagonal shape of the workpiece, following the example of the used nut.

After a hexagonal shape and optimal thickness was obtained, the machine parameters were transferred to a cut of 90 degrees. Further, the author, using the same machine, cut the required number of handles 64 mm long from a hexagonal blank.

Step three: Cutting the jaws for the clamp.

Further, the author began to process the second workpiece and cut sponges for the clamp from it. The tilt angle on the jaws is not mandatory, but rather serves for greater convenience. Therefore, the amount of inclination can be determined by yourself based on your preferences. The author made this part longer, after which he used it to cut an oblique angle for other parts and other blanks. An angle of inclination of 15 degrees, he considered the most versatile.

When using a joiner's corner, it is necessary to take into account the fact that the slope of the line is 50 mm by 70 mm. The corner piece should be set 12mm apart or centered in a 25.4mm wide workpiece. With this approach, the author recommends first cutting off the corner, and then cutting the jaws for the clamp to a length of 102 mm. These preparatory stages will allow you to reduce the chances of making any mistakes and ruining the workpiece, which means they will save materials and your time.

After cutting the blanks for the jaws of the clamp, the author divided them into two groups: he marked one group as sponges A, and the second as sponges B.
The division into two groups is necessary, since the sponges will have different attachments. Therefore, the work on drilling holes for them will also be different, it is easier to understand the difference between fastening from photographs of a ready-made clamp.

Step four: work on the sponges B.

To begin with, markings were made for drilling sponges from both groups. It is necessary to mark two holes with a diameter of 6 mm for the pins that will tighten the jaws. Two holes with a diameter of 6 mm should be located on the inner and upper surfaces of the jaws, passing through them. The first hole is 19 mm from the rectangular edge of the jaw and is located 9.5 mm from each side. The second hole is marked at a distance of 44 mm from the rectangular (rear) wall of the sponge and is also located in the center relative to the other sides. After which sponges B are laid aside.

Step five: finishing sponges from group A.

Jaw A is somewhat different from jaw B. Jaw A has two additional holes for cylindrical nuts, through which rods will pass to tighten the jaws of the clamp.

Therefore, in each jaw A, two holes with a diameter of 12 mm were drilled through one side, as shown in the picture. The first hole, 12 mm in diameter, shall be located 19 mm from the rear wall of the jaw and equidistant from the top and bottom faces of the jaw. The second 12 mm hole should be located 44 mm from the rear wall and equally spaced from the top and bottom edges. Thus, a set of jaws should be obtained with two holes along the center line of the outer planes of the jaws, as well as with two holes for pins with a diameter of 6 mm with inside sponges.

Step Six: Threaded Studs

Using a hacksaw, the existing stud with a 6 mm thread was cut into blanks of the required length. There should be two blanks from the hairpin for each clamp. One blank is 114 mm long, and the second is 127 mm long. After that, they were put aside until the stage of making handles for clamps.

Step Seven: Making Cylindrical Nuts.

In this case, cylindrical nuts are round steel parts with side holes drilled in them with a thread for a 6 mm stud. Probably, such nuts or something similar can be bought, but the author decided to make them himself.

For the manufacture of cylindrical nuts, a metal round blank with a diameter of 12 mm was required. Cylinders 19 mm long were cut from it, under the thickness of the jaws of the clamp. Then, holes were made in each cylinder on the side in the center, which, when the cylinders were placed in 12 mm holes on the jaws B, should coincide with the 6 mm holes on the same jaws B. After that, threads were cut in the holes of the steel cylinders at an angle of 90 degrees by 20 turns with a 6 mm tap.

Step Eight: Chamfering the Clamp Handles

In order to make it easier and more convenient to hold and tighten the clamp handles, each of them will have chamfers. In addition, such a detail makes appearance tool more attractive, according to the author.

To begin with, the blank for the handle was fixed, in this case in another ready-made clamp. After that, the author made a marking in the form of a hexagon on the outer surface of the workpiece, as well as a marking was made in the form of bounding lines on the sides of the future handle at a distance of 3 mm from the outer plane of the handle, as shown in the picture.

After that, with the help of a sharp cutter, chamfers were cut off and a handle blank with chamfers was obtained.

Step nine: creating a ledge on the clamp handles.

In order to be able to screw a 12 mm nut onto the handles, the handles must be cut to a diameter slightly larger than the hole of the nuts. In this way, the threads of the nut will securely engage with the wooden ledge of the handle, providing enough reliable connection. It would be convenient to process handles on lathe for creating desired diameter ledge, but you can also do it manually.

To do this, the author pressed the stop block to the saw guard, and used the 12 mm nut as a limiter for the depth of cut, as well as to ensure the required distance from the guard. After which it was taken wooden blank for each handle and made all the necessary cuts.
Thus, we got a picture that you can see in the picture above. Then cutting off all the extra protrusions, you should get a handle with a ready-made protrusion for the nut.

Step ten: turning the protrusion of the handles.

In order to put 12 mm nuts on the handles, it is necessary to cut off all the corners of the protrusion and grind the protrusion to the desired diameter. It is best to practice before this on some failed workpiece in order to understand to what extent it is necessary to grind off the protrusion and not spoil other workpieces.
To do this, the workpiece must be rigidly fixed and ground to an ideal cylindrical shape. After that, carefully, so as not to damage the workpiece, you need to screw the nut onto the ledge.

Step eleven: the final stage of making handles.

Clamp is an important tool for any craftsman. At the same time, the specifics of his work does not play a special role: a carpenter, a locksmith. This device is indispensable, therefore it is often used. For example, when gluing wood blanks to secure a sheet, slab, board, etc.

On the market you can find a large selection of clamps. They differ in the material from which they are made, sizes and other characteristics. Despite this, as practice shows, it is difficult to choose the best option for work. Most tools have their drawbacks, which provoke difficulties during use. One of the most important is associated with a low strength indicator. This is explained by the fact that the manufacturer wants to save costs on the manufacture of products, therefore, uses low-quality materials.

If you want a durable and reliable device, then the most the best way is to do it by hand. Such a tool will be an excellent assistant when working with wood and will last for many years. At the same time, it will save money on purchasing a new one, which is expensive. The design invented by you will help to solve individual problems quickly and easily.

A clamp is a device that is simple in design, but very important when processing wood. It is used to fix in one position a board, a plate and other things that need to be cut. It is very important that it be comfortable for its owner. This will allow you to complete the work quickly and efficiently.

You can get a tool that will meet your requirements only by making it yourself. To do this, the first thing you need to start with is to decide on the type of structure. The tool can be made of both metal and wood. Their scope is extensive. It can be both universal and specialized device.

If we talk about varieties, then we can distinguish tape, pipe, edge and others. As for the clamps, the mechanism is represented by the type of angular, screw, mounting, manual, quick-clamping. Last option is relatively new. It appeared quite recently, but is already actively used by masters, as it is convenient and practical.

Preparation of drawings

Making clamps is a simple process. Despite this, it requires attention and responsibility. In order for the resulting product to be of high quality and reliable, it is necessary to think through everything to the smallest detail.

First of all, you need a drawing. On a piece of paper, you can reproduce the device as it will be in the future. You can prepare it yourself. But here it is necessary to have certain skills in solving such problems.

And, of course, the best option is the help of a professional. He will take into account your wishes, prepare an individual drawing. But for his work you will need to pay a certain amount.

What is necessary?

Depending on the purpose for which the tool will be used, the material from which it can be made is selected. The highest quality and most reliable products can be obtained from wood, metal, corners, pipes and other things. These materials are great for making a clamp. It is also worth considering them high rate strength and durability.

In addition, you will need studs, nuts, plywood boards, slats. Their size is determined based on what the device will be. They are indicated on the drawings.

Manufacturing process: instruction

The process of manufacturing a clamp consists of several stages. It can be started after the drawings are prepared and necessary materials. At the same time, it is necessary to work carefully and accurately.

The first step is to fix the bars on the surface of the table. These will be used to secure the clamp to the workbench. To do this, you need to make holes on them by drilling. Then, using nuts with studs, press them tightly.

The second stage involves work with the lower beam. It must be stable on the surface. To do this, it is placed horizontally. The next one is placed on top. It should be edge to the countertop.

After that, you need to install plywood boards. A bar is placed on them, and everything is attached to the table. In this case, the bottom edge of the plank should protrude slightly. It will be enough three centimeters relative to the bar. After the elements are correctly laid out, they must be drilled through and fixed with studs. In this case, each board performs its role. One is responsible for how the lower beam is fixed, the second acts as a clamp.

At the same time, it is important to equip the structure with a plywood strip that moves. Studs for fastening are used different. They differ in length. So, long ones are responsible for the working stroke, short ones - for fixing the device to the table. As for nuts, their role is also great. They fix the part of the tool that moves and regulate the clamp itself, its strength. Thus, they act as leverage.

Do-it-yourself quick clamp

Quick clamp do-it-yourself - one of the most common types of construction. She happens different types: angular, lever, manual and other. Its main difference is that the device provides a quick clamping of the material to be processed.

It is not difficult to make such a clamp with your own hands. To do this, it is necessary to take into account some of the nuances of the case. The first is related to a good clamp. A lever is excellent as it, which helps in working with the tool. Such a device will be convenient and practical to use.

If the tool is used for welding, then it is necessary to choose an angular model. She will allow necessary work perform quickly and simply, as it is a universal fixative.

Every craftsman who deals with products and details made of metal or wood cannot do without homemade clamps. Previously, such a tool was produced in various modifications, from specialized to universal. The main task is to fix the workpiece for processing and joining operations. We will analyze how a do-it-yourself quick-clamp clamp is made in various variations.

Angle clamp

This type of do-it-yourself metal clamp is designed to fix two objects at a right angle and connect them to each other by any means, however, the main purpose is a jig for welding metal parts at an angle necessary for work. To make it properly you will need the following components:

Corners should be welded at a 90 degree angle to metal or steel plates. We fix the worm structure by welding, and screw the stud-knob into the working nut in order to assemble the stop at the end. The stop must be free to rotate. Then with reverse side it is necessary to drill a hole where we insert a metal rod as a lever. Incredible simple design and practicality of use have become the key to the popularity of such a clamp among all those who work with metal and products made from it.

Joiner's clamp

Such designs used in carpentry are of the following types:

• Standard clamp, which is the most popular or simple;
• In the form of a caliper for parts small size and operational fixation;
• Self-clamping clamp for milling processes and working with workpieces of various heights.

The first type is made from two pine blocks, lock nuts, rods, threaded lamb nuts and thrust washers. The manufacturing process is very simple:

1. We cut out working pliers from the bars, drill holes for the studs, taking into account a small backlash;
2. We screw the studs and counter them in the appropriate ways;
3. We provide convergence with nuts, made either in the form of wing nuts or standard nuts for improved tension.

The second option is used when prompt fixation of small parts is necessary. Production is carried out from small bars and thin-sheet plywood. The worm system is nuts for furniture and studs-collars. One stop is fixed, we fix it at the end of the guide rail, in which we cut out recesses to fix the moving mechanism.

There is both a portable and a stationary version of this design, where grooves are cut for movement with fixed stops fastened. The clamp is a furniture nut, a hairpin and a knob. Due to this, it is possible to work with blanks of any dimensions.

The self-clamping design has a lever with an eccentric at the swivel end. We turn to a certain angle, a quick clamp is automatically obtained. The height is adjustable with a pin on the workbench. It is made individually for each matrix, depending on its purpose and the purpose of the work being carried out.

Pipe clamp

Welding metal pipes butt to butt is a complex operation. It is considered simpler to weld the pipe to the finished system. The design for such cases is made of metal corner and steel plates. The halves of such a device should be fixed traditional method, namely threaded studs. As a result, a fairly simple and efficient design can be obtained, which will greatly facilitate the work when welding pipes with various designs.

There are other types of designs, including cams, belts and wire clamps, that can be useful for working with specific designs, including especially fragile and thin ones. However, their production is the subject of separate master classes and articles on specialized resources.

Homemade clamps are indispensable assistants for any craftsman working with metal and wooden details and products. To make them is quite simple and very exciting. It is important to follow the manufacturing technology, find the best instructions and videos. You can buy clamps, but they may not be suitable in the end due to the specificity of the blanks or work. That is why you should make clamps yourself. Good luck working with various blanks and making homemade quick-clamp clamps!

Buying clamps is very expensive. Therefore, in order to avoid unnecessary expenses, it would be useful to know how to make a clamp with your own hands. Quite often, in the manufacture of furniture or wooden products, clamps are required in in large numbers. Especially if wooden crafts produced professionally. To make clamps on your own, you will need primitive improvised materials that everyone has available. In addition, the work process itself is not complicated and does not require professional skills, which will allow you to quickly create the necessary auxiliary tool.

Clamp scheme: a - parts, b - assembled, 1 - rectangular hole, 2 - pusher, 3 - body wall, 4 - ledge, 5 - hole in the body, 6 - clamping screw, 7 - movable jaw, 8 - lever, 9 - ledge, 10 - threaded holes, 11 - screws.

What is a clamp, and is there any point in making it yourself?

A clamp is an auxiliary tool that is used to fix the boards when they are connected (using glue, fasteners, etc.) or, if necessary, to compress them. Usually clamps are made of metal or wood. A clamp is also used to cut boards evenly, to make wiring for a hacksaw, to connect various parts and elements, etc. At the same time, homemade clamps are in no way inferior to purchased ones. To understand the principle of making a clamp with your own hands, you should understand its design.

Such clamps consist of 2 elements - a “body” (frame) and a fixing element (movable clamp). There are clamping jaws on the movable element and the frame, and for better fixation, the movable element is equipped with a lever. Sometimes there are lever clamps, but they are rare due to their complexity in production, both in industrial enterprises and at home.

The operation of the clamps is simple: parts (or material) that require processing are inserted into the body of the tool, then the working material is clamped with a moving element (clamping occurs with sponges), after which you can start processing or working with parts or material.

In most cases, the number of clamps required for a particular operation is not limited to 1 pc. For a tight fixation of the hacksaw, use 2 pcs, for fixing wooden planks- from 2 or more (depending on their length). In addition, if you want to connect parts, it is recommended to use a pair of clamps. Many people forget to take them off after work is done, which often leads to the loss of the tool. And primitive factory-made metal clips are not cheap, which makes it cost-effective to make such tools yourself. Below we will consider how to make carpentry clamps from wood and metal, and how an angle clamp is made by hand.

Making a wooden clamp

It is much easier to make a wooden clamp than all other types of such a tool. Such clips are very convenient when performing various carpentry work.

To make them you will need:

• pieces of boards (you can plywood);
• studs (which should be pre-threaded);
• nuts (for threaded studs);
• slats.

For the manufacture of the clamp, two studs 200 mm long with pre-threaded threads and 2 studs 120 mm long should be prepared. It is important that all 4 studs have the same diameter. Next, nuts are selected under the thread of the studs, two rails are prepared. Reiki should be prepared from hardwood. Oak is ideal, but beech, birch or ash slats are also suitable.

Then the slats need to be made the same in size. To do this, saw off all the excess and produce grinding. Then 2 holes are drilled in each rail. The holes must be at the same points on each rail. The diameter of the holes must match the diameter of the studs.

The next step is to stick plywood (as sponges) on the surface of the slats. When the plywood is glued, all the protruding parts are cut to the size of the battens, and the plywood sponges themselves are drilled through the holes in the battens.

Then long slats are inserted into the resulting holes. They will act as guides.

After the guides are installed, they are fixed with nuts to the rails. 2 nuts are screwed onto each guide.

Next, insert short studs. To make them immovable, the studs are riveted on one side. It is important that one stud is riveted from the back of one rail, and the other from the back of the other. Nuts are used as clamps. In order to make it more convenient to tighten them, lamb nuts are used. In this case, it is important to cut the threads on the fixing studs along their entire length.

This completes the manufacture of the wooden clamp.

How to make a screw metal clamp

To make such a clamp, you first need to prepare the materials. For the body of the clamp, you can use a sheet of steel about 1 cm thick or even and straight metal cuttings of the same thickness. The length of the workpiece depends on what working distance the clamp will have. For manufacturing, you will need long screws or bolts M8 or M10.

At the beginning of the manufacturing process, markings of the future tool body are applied to the workpiece material. Often the body of the instrument looks like the letter "C". In this case, the thickness of the workpiece can be different. It depends on the required length. working area. When the markup is applied, the part is cut out. To do this, at home use gas cutters, acetylene torches or a grinder. The grinder is used for workpieces of small thickness, it is problematic to use it when cutting out small curly elements.

When the workpiece is cut, it is polished with files, sandpaper. Grinding is important process, if you do not grind the part, then there is a chance of cutting yourself on sharp edges when working with the tool.

Then, on one side, fasteners are made for the movable element. To do this, M8 or M10 nuts are welded to one of the sides of the clamp body. If there are no bolts or screws of sufficient length, hexagons or rebar of the desired length can be used. They should be threaded first. A flat flat part (on the working side) is welded to the end of the screw, which will act as sponges. A lever is welded on the opposite side (studs can be used as a lever), which should simplify the clamping process. This completes the manufacture of the clamp.

Another option is to make a clamp like a caliper. For this, a sliding frame made of steel strip is used. The end of the strip is flattened, and sponges are welded to it. Further, a movable element is made from the same strip, to which nuts are welded and a screw is screwed in for fixation.

It is more difficult to make such a clamp, but it has a longer stroke and, accordingly, a larger working area.

Angle clamp

In order to manufacture angle clamp, you need to accurately maintain the angle of 90 o. To do this, you need a square. Corners and steel strips can be used as materials.

To make such a clamp, you should install a square, to which the corners are applied so that the legs of the resulting rectangle are equal. Next, the corners are fixed on the square with improvised materials. Metal strips are applied to them. The strips should be fixed and then welded.

Nuts for moving elements are welded to the corners. It is advisable to use 2-3 nuts for this. Their task is to provide the best fixation. As fixing elements, you need to use long bolts or metal rods with threaded threads. At one end they should be welded on a flat plate as sponges, and for more convenient operation, a welded lever is used. This work is completed.

Angle clamp is the most difficult to manufacture, however, for some jobs it is simply irreplaceable.
