Do-it-yourself corner carpentry clamps in Mozyr. Making carpentry clamps for welding yourself

A do-it-yourself clamp is made according to a pre-prepared pattern. The tool is presented in the form of a clamp, which is used to fix various parts. Carpenter's clamps are used for sawing, spreading saw teeth or sharpening them.

A quick-release clamp is a type of hand vice that is used to firmly secure workpieces or parts.

Principle of operation

A quick-release clamp is a type of hand vice that is used to firmly secure workpieces or parts. The main elements of the device include the frame, moving part, lips, and valve. Experts recommend making tools from iron.

The quick-release tool can be locked using one hand. The object is inserted between the jaws, pressing it with the movable system. Then the product is fixed with a valve. Experts include the following advantages of the design under consideration:

• light weight;
• ability to fix large parts;
• high strength;
• transportation;
• fast completion of work.

A quick-release clamp is used for release. To do this, you will need to dismantle the stops and lips, turning the last elements over. Using this tool you can process glass.

Components

Do-it-yourself clamps made from light metal quickly fail. The parameters of such units do not exceed 2 m. To press the dimensional sheets of plywood, you will need to make a sliding homemade clamp.

Experts include the following components of the design:

• frame;
• clamping jaws;
• movable part;
• lever component.

The movable design changes the pitch between the jaws using threads. From a constructive point of view, the lever device consists of levers and eccentrics. This tool is difficult to make at home.

To make a wooden clamp, use a diagram and the following tools:

• threaded studs;
• slats;
• nuts;
• plywood.

The length of the studs should be 120 and 200 mm, and the diameter should be 5 mm. The size of the plywood boards is 15x150x200 mm, and the parameters of 2 slats are 20x40x240 mm.

Step-by-step instruction

The production of homemade clamps involves the use of wooden blocks made from oak, beech, birch or ash. Such tools are fixed to the working surface. In the bars with which the clamping part is attached, 2 holes are made. This technology ensures tight fixation of the nut with the stud.

To obtain a stable and reliable structure, it is recommended to place the bottom bar flat.

The next step is to install the plywood boards. A block is attached to them. The bottom edge of the plywood must be positioned 3 cm below the block. The blanks are drilled. Pins are inserted into the resulting holes.

Plywood is used as a clamping element. Such clamps grip parts with a movable strip. The tool is fixed to the surface of the tabletop using short pins. Long analogues determine the working stroke of the clamp. Nuts are a lever that secures a moving element by adjusting the clamping force.

A homemade clamp for welding can be made from a hacksaw, 2 threaded rods and a nut. The last elements are inserted into the clamp connectors. The nuts are put on from the inside of the device. The resulting tool has 2 standard sizes. To prevent the body from breaking into 2 parts, the folding element is wrapped with electrical tape. The versatility of the resulting device lies in the possibility of turning it back into a hacksaw. Steel fasteners are used to secure the sliding structure of the tool. It is not recommended to use a homemade clamp to the limit of its capabilities. Otherwise, it will quickly fail. The universal clamp is made from a channel.

Its length depends on the maximum dimensions of the material being processed. The thickness of the channel is selected taking into account the frequency of use of the future tool. Places for holes for bolts are placed along the axis of the channel. The last fasteners are welded to the thrust structure. The holes are cut with a welding machine. To achieve a tight fit of the stop, the nest is made in the form of a drop. A bolt is welded to the channel. The size of its head must correspond to the diameter of the socket.

A clamp is a tool for fixing parts during processing. Experts from the publication tell you today how to make a good clamp with your own hands and save money.

What types of clamps are there?

A simple carpenter's clamp is simply an irreplaceable thing in the woodworking process. A clamp is used if you need to secure a board, sheet, or slab when cutting. Those who work with wood quite often prefer homemade carpentry clamps.

IMPORTANT! The quick-release clamp is capable of developing a compression force of up to 450 kg.

Typically, homemade clamps are made from wood or metal. Not a single master can do his work without this tool, which is produced in various versions - from universal to specialized.

There are different types:

According to clamping mechanisms:

Like any other necessary household tool, clamps can be purchased at any construction or hardware store, but homemade ones made at home will be in no way inferior to factory clamps.

IMPORTANT! Before making even a simple tool design, take care of the drawings.

Pipe clamp

High-quality and reliable clamps are obtained if they are made:

• made of wood;
• made of metal;
• plywood;
• pipes;
• channel;
• profile pipe;
• corners and bolts.

How to make a clamp with your own hands: step-by-step instructions

Manufacturing process:

1. for production you need: a pair of studs, the thread length of which is 200 mm and Ø about 5 mm; another pair of studs with the same Ø, but with a thread length of 120 mm, nuts, a pair of plywood boards measuring 15x150x200 mm, a pair of slats measuring 20x40x240 mm;
2. homemade clamps are attached to the surface of the work table: we use bars prepared for fastening the clamp to the workbench; several holes are drilled on them to tightly press the nuts and studs together;
3. For stability, the lower beam is placed tightly (flat) on a horizontal surface, and the upper beam is placed with its edge towards the tabletop;
4. Next, plywood planks are installed, and a block is attached to them, which is attached to the surface of the table. It is important to ensure that the bottom edge of the boards is 3 cm below the block;
5. all three elements are drilled through, and pins are fixed in them a little later;
6. one board is fixed to the bottom bar, the second board will serve as a clamp;
7. the clamp is made using a movable plywood strip;
8. short pins secure the clamp to the table surface, long pins determine the working stroke. Nuts - for fixing the moving part and adjusting the clamping force; in the design they act as levers.

Step 1 - The simplest wooden clamp is made from two wooden blocks (pine will do). Wood that is too hard will leave marks on the workpiece if held tightly Step 2 - Furniture nuts with wood locking Step 3 - Steel studs, they do not have to be hardened steel Step 4 - Wing nuts with threads that match the studs Step 5 - Thrust You can use regular washers. Working pliers are cut out of the bars. Holes for the studs are drilled strictly in parallel with a slight backlash. The studs are screwed into furniture nuts. Toe-in is ensured by wing nuts or regular nuts with an open-end wrench (if a strong grip is required) Step 6 - Finished clamp

How to use homemade clamps?

Lever clamps do not require any special force from the master at all: to clamp the part well, you just need to use a lever that does the work for a person. The remaining types of quick-release tools have different clamping mechanisms, but they are all convenient.

For welding, an angle clamp is used, thanks to which welding work is performed much faster and easier. It is the universal fastener that securely fastens the processed surfaces at the required angle during welding (from 30 to 90 degrees).

A pipe clamp is used when welding metal pipes end to end, since the task is quite complex, requiring not only skills, but also precise orientation of the workpieces in space.

Typically, pipe clamps are made from ½- or ¾-inch water pipes onto which a fixed stop and a movable jaw are screwed. The clamp can be of any length; you just need to cut a thread at one end of the pipe and then screw the stop onto it.

The clamp can be moved to a pipe of a different length or removed at any time.

DIY pipe model:

Wooden clamps are much easier to make than other types:

A wide range of tape clamps are designed for convenient gluing of frames and drawers; they are used in the repair of wooden chairs, frames, table tops, and aquariums.

The clamp is based on a belt, nylon or leather. It is with its help that the clamping force is transmitted to the mating parts. Provides any workpiece with uniform pressing force and strong fixation.

Manufacturing process:

Carpentry clamps include f-shaped clamps, which are a combination of a fixed jaw at the end of a flat steel base and a sliding adjustable jaw. They have a deep mouth that allows you to fix the part far from its edge.

An eccentric lever or an adjusting screw may be installed on the clamp jaw at the sliding head.

There are two types of clamps:

• Light duty (for easy use) - thin and narrow, do not take up much space and are characterized by low weight;
• Heavy duty (for heavier work) are characterized by simplicity and low cost.

IMPORTANT! The latter are not very convenient to use, since you have to hold them with both hands and then twist them.

In the manufacture and for fastening furniture panels, doors and windows, a clamp is used.

Divided into two types:

1. open ones are used for gluing boards into a shield and tightening tenons when assembling wooden doors and windows;
2. closed ones are used only for gluing panels.

Closed-type clamps consist of two tires, while the shield is clamped from below and above between the tires, which prevents the shield from warping when tightened.

A hand vice (clamp) is used to securely hold various parts when gluing, cutting or processing. It is thanks to the hand vise that it is possible to obtain a stable position of the desired part.

IMPORTANT! A hand vise is not a regular vise that screws onto a table. They consist of two main parts - a fixed one (rod frame) and a movable one, with the help of which the clamping distance is adjusted and the part itself is fixed.

Pressing clamps are perfect for circular saws, used for precise and accurate sawing of small pieces of material, bending and other operations with wood.

What else are carpentry clamps used for?

• for fastening various elements during furniture assembly, for gluing boards, directly furniture boards, gluing boards;
• attaching the echo sounder sensor to the end of the boat. Clamps are also used for tying flies;
• The clamp can be used to mount a table lamp. A lamp with a clamp is a lamp that is attached to a table. It has a clamp that is firmly fixed to the surface. The column of the table lamp has a flexible design that allows you to adjust the light source in any desired direction;
• the saw blade for the grinder is secured with clamps;

IMPORTANT! If there is no pipe or shelf on which to attach the clamps, you should consider a small holder for storing them. To do this, just attach two triangular planks to the wall panel, and place the clamps themselves between them. Perhaps it will be a pair of holders - short clamps can be hung on one side, and long ones on the other.

• The belt model, which serves to secure large or complexly shaped objects, is most often used for gluing frames. The device body can be made of nylon and metal, which guarantees a long service life;
• for screeding floorboards;
• for repairing car fenders;
• for the manufacture of floor stocks, miter saws;
• for binding documents in office work and for archival binding;
• to close the watch cover. When cleaning, replacing batteries and doing other work with chronographs on your own, you are faced with the problem of how to close the back cover of your wristwatch. This is not easy to do if it is an expensive Swiss watch, since the mechanism is secured quite tightly to avoid leaks;
• in a shoe workshop they use special shoe clamps that you can actually make with your own hands. With these devices, shoe repair occurs much better and faster.

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, when making furniture or wooden products, large quantities of clamps are required. Especially if the wooden products are made professionally. To make clamps yourself, you will need primitive materials at hand, which everyone has in stock. 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.

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

A clamp is an auxiliary tool that is used to secure boards when connecting them (using glue, fastening hardware, etc.) or if it is necessary to compress them. Typically clamps are made from metal or wood. The clamp is also used to cut boards smoothly, make routing for a hacksaw, 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 - the “body” (frame) and the fixing element (movable clamp). There are clamping jaws on the moving element and the frame, and for better fixation the moving element is equipped with a lever. Lever clamps are sometimes found, but they are rare due to their complexity in production, both in industrial enterprises and at home.

The way clamps work 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 (the clamping occurs with jaws), after which you can begin processing or working with the parts or material.

In most cases, the number of clamps required for a particular operation is not limited to 1 piece. To tightly fix a hacksaw, you should use 2 pcs., to fix wooden boards - 2 or more (depending on their length). In addition, if you need to connect parts, it is recommended to use a pair of clamps. Many people forget to remove them after completing work, which often leads to the loss of the tool. And primitive factory-made metal clamps are not cheap, which makes it economically profitable to manufacture such tools yourself. Below we will look at how to make carpentry clamps from wood and metal, and how to make a corner clamp with your own hands.

Making a wooden clamp

A wooden clamp is much easier to make than all other types of such tools. Such clamps are very convenient when performing various carpentry works.

To make them you will need:

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

To make the clamp, prepare two pre-threaded studs 200 mm long and 2 studs 120 mm long. It is important that all 4 studs have the same diameter. Next, nuts are selected for the threads of the studs, and two slats are prepared. The slats should be made from hardwood. Oak would be ideal, but beech, birch or ash slats are also suitable.

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

The next stage is gluing plywood (as sponges) onto the surface of the slats. When the plywood is glued, all protruding parts are cut to fit the slats, and the plywood jaws themselves are drilled through the holes in the slats.

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

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

Next, you should insert short pins. To make them motionless, the studs are riveted on one side. It is important that one pin is riveted from the back side of one batten, and the other from the back side of the other. Nuts are used as clamps. To make it easier to tighten them, wing nuts are used. In this case, it is important to cut the threads on the fixing studs along their entire length.

This completes the production of the wooden clamp.

How to make a metal screw clamp

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

At the beginning of the manufacturing process, markings of the future body of the tool 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 only on the required length of the working area. When the markings are 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 when cutting out small shaped elements.

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

Then fasteners for the moving element are made on one of the sides. To do this, M8 or M10 nuts are welded to one side of the clamp body. If there are no bolts or screws of sufficient length, you can use hexagons or reinforcement rods of the required length. They must first be threaded. A flat flat part (on the working side) is welded to the end of the screw, which will serve as jaws. A lever is welded to the opposite side (studs can be used as a lever), which should simplify the clamping process. This completes the production of the clamp.

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

Such a clamp is more difficult to manufacture, but it has a longer stroke and, accordingly, a larger working area.

Angle clamp

In order to make a corner clamp, you need to accurately maintain an angle of 90 degrees. To do this, you will need a square. Angles 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 using 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 better fixation. Long bolts or threaded metal rods should be used as fixing elements. A flat plate should be welded onto one end of them as jaws, and for more convenient operation, a welded lever should be used. At this point the work is completed.

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

The clamp is an auxiliary tool , which is used to fix the boards when they are connected in a given position. The clamp is also suitable for holding boards while sawing them, for routing the hacksaw blade, and connecting various elements. Parts that require machining can be inserted into the tool. Then, using a movable element, they are clamped with jaws and begin to work. To securely hold parts in the desired position, it is recommended to use two or more clamps.

Homemade clamps are often made of metal or wood, and in terms of their characteristics they are not much inferior to purchased, factory-assembled ones. Since the design of the clamping device is simple, it will not be difficult to understand the principle of its operation in order to make it yourself.

Making a metal screw clamp

Before starting work, you will need to prepare the necessary materials. For the base of the structure, a steel sheet one centimeter thick, or any even trim of the same thickness, is suitable. The length of the workpiece is arbitrary, but they try to choose it taking into account the working distance of the clamp.

Main materials of manufacture:

• steel sheet;
• long bolts;
• nuts

A drawing is being drawn up. The future body of the tool is marked on the workpiece material, which in appearance resembles the letter “C”. Instead of a steel sheet, you can use a section of profiled pipe, bent in the shape of the letter “C”. There are no special requirements for the thickness of the workpiece, but the design must be reliable. The choice of length is made taking into account the dimensions of the working area and the parts being processed.

After marking is applied, the part is cut out of metal. At home, small pieces can be cut using a grinder. But when making clamps of large dimensions, it is recommended to use a gas cutter or an acetylene torch. The next stage is processing and polishing the workpiece. All sharp edges and sagging formed when working with gas welding equipment are knocked off with a file, and the surface is sanded with sandpaper. This must be done so that when clamping the workpieces, you do not cut yourself on sharp edges.

Having prepared long bolts M 8, M 10, proceed to fastening the moving element. Why are nuts welded on one side of the workpiece under the selected bolts? If there are no bolts, you can select hexagons or steel rods of the required length with pre-cut threads.

At the inner working end of the screw, a flat, even part is welded, on which the function of the jaws is assigned. On the reverse side of the screw, a lever is attached by welding from scraps of a stud. Its presence will speed up the process of clamping workpieces , further reducing the amount of effort applied. This completes the assembly of the clamp with your own hands.

Corner clamp device

When making corner tools for furniture assembly, it is important to accurately maintain a right angle of 90°. The main materials available are angles with steel strips. To work you will need:

• 40 mm steel angle 3-4 mm thick;
• steel plates 40-50 mm;
• threaded studs;
• rods for gates;
• nuts;
• welding machine;
• electric drill, taps.

The corner clamp is the most difficult to manufacture, but when carrying out some types of work you cannot do without it. At the initial stage, corners are welded to the steel plates at right angles, and nuts are welded to each corner, which will serve to create a worm-type structure. Another option is to drill a hole in the corner and cut an internal thread in it using a tap. The width of the working gap is selected taking into account the size of potential workpieces, but too large a stroke of the clamping wheel reduces the strength of their fixation.

To process parts of different sizes, it is recommended to prepare several clamps!

The stud is screwed into the welded nut. At its end, a stop is assembled from metal washers of various diameters, which should rotate freely when the pin rotates. On the back side of the knob, a hole is drilled for a metal rod. Used as a lever, it will transmit more force, so it will hold workpieces more reliably.

Wooden clamp - made from leftover boards

The most popular is a wooden quick-release clamp, but a tool of a similar design can also be made of metal. Despite the simplicity of the design, it is very convenient when performing various tasks.

The presence of two identical clamps expands the scope of their application!

For assembly you will need to prepare the following materials:

• pieces of boards;
• studs with pre-cut threads;
• nuts and wings corresponding to the threads of the studs;
• slats.

First, two studs of the same diameter with threaded threads are prepared. They must be 200 mm long. The nuts are matched to the threads of the studs. Two slats are prepared, preferably from hardwood. The best choice would be oak, beech, birch, ash. The slats are adjusted to the same size. To do this, the excess length is sawed off and the cut is sanded. After this, two holes are drilled in each of the slats with a small tolerance. Moreover, the locations of the holes on each of the workpieces must match perfectly, and their diameter must correspond to the diameter of the studs.

Strips of plywood can be glued to the surface of the slats. They are adjusted to the size of the wooden blanks and holes are drilled. The studs are inserted into the resulting holes and securely fixed with nuts on one of the rails on both sides. To prevent material from pushing through, washers are placed under the nuts. This bar will always be stationary, but the other one will be able to move freely along the guides in the form of pins.

Another bar is installed. To do this, thread it through the studs and push it into place. The clamping is carried out using ordinary nuts and an open-end wrench, but for convenience and increased performance it is necessary to install wing nuts. Check the movement of the fastener; if it is difficult or additional adjustment of parts is required, or other defects are found, then they are eliminated. The work on assembling the wooden clamping device can be considered completed; all that remains is to test it in action.

Properly assembled clamping devices allow you to securely fasten wooden parts during carpentry work. The designs of the listed types of fasteners are popular and are so simple that they can be made independently from scrap materials using a minimum number of tools.

Beginning craftsmen, perhaps, at the first stage of their work, make do with only two tools: a hammer and a hacksaw. But as you gain experience, their number no longer becomes enough. You always need to glue two parts together and secure something in a vice or clamps. Making a clamp with your own hands is very easy and simple.

Using the tool, types and its structure

There are no clamps that would one hundred percent meet our needs when carrying out work around the house. Clamps come in different shapes, models and sizes. As a rule, there are not enough of them. Below is a short list of devices for solving assigned tasks in wood and metal processing:

• wooden;
• metal;
• F-shaped;
• C-shaped;
• corner;
• cam;
• G-shaped;
• wire clamps;
• ribbon clips.

Making a clamp yourself is quite simple. Of course, when carrying out work, this is not a tool that is constantly needed. But it doesn't hurt to always have it on hand.

Wooden clamp for screed

One of the most accessible and inexpensive examples to make yourself. It is easy to do and easy to use. For its production, maple or pine planks are taken. Their minimum width can be 5 cm, thickness not less than 0.6 cm. A metal rod with four nuts is used as a lock. To make a handle, you will need any hardwood that does not have visible external defects. The moving part is completely dried and can easily be moved along the metal rod.

At the ends of the rod there are two nuts that are tightened to prevent divergence. You can use a simple locking nut, as well as the original nut with a stationary lock. Additionally, two more nuts and washers are screwed on both sides. These nuts lock each other. Be sure to leave an opening for the rotating pin.

Wooden and steel clamp

It is also shaped like the letter F. Its key difference is the use of metal parts. The durability and strength of the metal plays an important role in this case. The most difficult part is the plate itself, into which the bar will later be inserted. Several holes need to be drilled. When finished, you can clean the metal using a grinder. The plate must move easily on this plate. A gap is drilled at the opposite end of the plate, which should match the thread of the screw stud.

The end should be made at an angle to fully match the cutouts. This is done easily by grinding on a machine. How to make the remaining parts was discussed above.

DIY F-shaped clamp

It is made from both wood and metal. It is shaped like a caliper. It is made from durable wood or plywood sheets. You need to cut recesses on the rail to fix the movable device itself. Typically a worm system for moving the bar is used. The parts are secured with a holder, which is secured with a few turns of the nut. When the holder is released, the part is easily removed from the clamp.

The principle of operation of the clamp

When a specialist works with wooden and metal workpieces and needs to fix the product for precise processing. This can be done using clamps.
Ancient models allowed it to be fixed with one hand, modern models free both hands of the master. Not only are they quick-release, but at the same time they allow you to use both hands. The following types of clamps are known:

1. Assembly.
2. Manual.
3. Angular.
4. Screw.
5. Lever.

Lever clamps are based not only on the worm-screw principle of operation, but also on the lever mechanism. They are also called clamps. They make it possible to accurately and instantly fix the part. The use of enormous force is not required here; all the main work is done by levers. These clamps have a very simple design, so you can make them yourself at home. This principle of operation allows not only to fasten the part, but also to calculate the compressive force. This is important, for example, when gluing.
Other types of clamps differ only in the method of fastening the parts.

We make carpentry clamps

When working with wood, you often have to fix it, so you can’t do without a carpenter’s clamp. You will definitely need it when you just need to fasten boards or glue together pieces of wood or sheets of trees.
Undoubtedly, such models are commercially available. But they are made from softer alloys, so manufacturers reduce the cost of goods. And they don't always fit in size. A DIY clamp is the best option.
There are a huge number of modifications of clamps on the market. Some of them can be universal, and some are completely disposable and they are made for one technical operation. You just need to understand the principle of operation, then making any option with your own hands will not be difficult. There are no manufacturing standards.

The simplest option is from a hacksaw for metal. She gets ready quickly. But its use is limited. Although this functionality is sufficient for working with small objects.

The fastening elements are bolts, at one end of which there is a nut, at the other end there may be a removable handle or open-end wrench.

Since the frame can be adjusted in length, this will allow you to work with workpieces of different widths. Mainly used for gluing parts. It will not be possible to attach it to the table, since the design does not allow it. But if there are no other suitable tools, then this option will come in handy as always.

Manufacturing of bench clamps

Locksmith work in an unequipped room always has one constant problem that locksmiths have to face, this is the fastening of workpieces. It is impossible to exclude movement of the workpiece on the table if the table is not equipped with fasteners. One of these affordable and very simple means is a DIY bench clamp.

In order to make a clamp with your own hands, you need to have minimal skills in plumbing. For its production, wood, studs, rolled metal, pipes, and wooden beams are used. It also wouldn't hurt to have a welding machine. The most important thing when carrying out any work is to follow the instructions and observe safety precautions.

Consider the option of making a clamp from wood. You can choose the size yourself, which one is most suitable for the type of work. The end result should be a screw type clamp.

1. Transfer the templates of wooden blanks to a sheet of cardboard. The sizes are selected independently.
2. Next, transfer the blank templates to a wooden board. A variety of hardwood is ideal for these purposes.
3. The part is cut out using a hacksaw or jigsaw. The contour of the part is processed with a file and sanding paper.
4. In the center of the workpiece, mark the location for the hole. The bolt axis will pass through it. The hole in the upper part of the fixing jaw is widened with a round file to dimensions 1.5 or 2.5 times wider than the size of the bolt itself.
5. Drill a hole in the handle for the nut. The diameter must match the number of the wrench. Use a rasp or file to shape the hole into a hexagon. We seat the nut in the hole with epoxy resin and, alternatively, any other solid adhesive.
6. The clamp is assembled, the bolt is secured with glue in the lower part of the fixing jaw. Loops are attached at the back to open the fastening jaws. Place the upper jaw on the bolt and tighten it with a handle.

In fact, there are a large number of examples for making clamps at home. For these purposes, for example, it is possible to remake metalworking hacksaws.

Making a clothespin clamp

One of the simplest and most popular clamps is the clothespin clamp. Making a clamp with your own hands is very simple. The principle of operation of such a clamp is similar to the principle of a clothespin. Only the sizes here will be larger.

First you need to cut out blanks from plywood. In total you need to prepare 10 such parts. Five out of ten should have a rounded bulge in the center. The length of each jaw of the holder is 15 cm.

It should be noted that if you need a larger model, then you need to use stronger and thicker plywood.

We begin to glue the profiles of the blanks one by one. First there should be a profile with a convexity. There should be two such clamps. We connect them together so that the ridges fit into the grooves.

If everything is done correctly, then such a clamp will be movable and work like a clothespin. We wrap an elastic band around a clamp. That's all, the DIY clamp is ready.

How to choose a clamp when purchasing

The clamp is a fairly simple device and there should be no problems with the choice. The main thing before buying is to check its serviceability so that the body does not have cracks. The screw part should be easy to screw in and out. See how tightly the lips fit. They should be even. If the kit includes rubber gaskets, try them out. They are needed in order not to leave marks on soft materials during fastening. The device must also be lightweight and durable.
