Do-it-yourself repair of large vise locksmiths

In detail: do-it-yourself repair of a large locksmith's vice from a real master for the site my.housecope.com.

It is not difficult to make a reliable and easy-to-use vice with your own hands. The need for this may be caused not only by the desire to save money on the purchase of a serial model, but also by the need to use a clamping device, which will more efficiently solve the tasks assigned to it.

Simple homemade vise from the corners

Serial vise models, although they are universal, are not always able to provide high accuracy of fixing parts, they are rather bulky and are distinguished by significant weight.

Homemade vices, used mainly in a home workshop, can be made more adapted to perform certain technological operations, and therefore more efficient and convenient.

Homemade locksmith vices may differ little from factory ones both in appearance and in reliability.

Anyone who spends a lot of time in their home workshop will confirm that it is quite difficult to do without such a device as a vice. Without a clamping device, it is difficult to perform various operations with parts made of metal, wood and plastic. The use of a vice guarantees not only high accuracy and efficiency of drilling, milling, etc. operations, but also the safety of the machine operator. If there is no desire or opportunity to purchase a serial model of such a device, then it is quite possible to make a vice with your own hands, spending very little time and effort on it.

Excellent strong locksmith vices can be made from shaped pipes yourself. Below is a detailed instruction in the format of a photo compilation, supplemented by a detailed video. Unfortunately. video in English, but this is unlikely to prevent a competent master from understanding the essence of the process.

Homemade vise from profile pipes

Homemade vise does not require complex design developments and calculations. You can use the numerous photos and drawings of such devices, which are easy to find on the Internet. A fairly simple, but at the same time very effective design is created on the basis of metal pipes.

As you know, pipes used for the installation of water and gas pipelines are produced in such a way that a product of a certain diameter fits tightly into a pipe of a subsequent standard size. It is this feature of pipes that allows them to be used for such a device as a homemade locksmith vice. A visual drawing, a photo and a description of the manufacturing process will help you make these vices yourself.

A drawing of a homemade vise. Below are two photos with the finished product

The structural elements of which the homemade vise will consist are:

a piece of metal pipe, which will act as the inner movable part of the device;
a piece of metal pipe of the next standard size, which will serve as an external fixed part;
a running nut with a thread diameter M16;
lead screw with thread diameter M16;
a knob, due to which rotation will be imparted to the lead screw;
front and rear supports, due to which the stationary pipe will be fixed on the base;
pieces of rectangular pipe (future vise clamping jaws);
two lock nuts with thread diameters M16 and M18.

Two main parts of the vice (movable and fixed)

They begin to make such a vice with their own hands by welding a flange to the end of a section of a pipe of a larger diameter, which will act as a fixed element. An M16 threaded nut must be welded into the center hole of the flange.A flange with a central hole is also welded to the end of a section of a movable pipe of a smaller diameter, into which the lead screw will be passed.

At some distance from the edge of the lead screw, an M18 nut is welded to it (it will become a fixing element). After that, the end of the lead screw, to which the nut is welded, must be passed through the inner part of the movable pipe and inserted into the hole in the flange. In this case, the nut should press against the flange from its inner side.

Vise assembly (in the photo, a hammer is clamped in them)

A washer is put on the end of the lead screw, protruding from the outer side of the flange, and an M16 nut is screwed on, which is then welded to the screw. A washer must also be fitted between the inner nut and the flange face to reduce friction. To correctly complete this stage of making a homemade vise, it is better to focus on the corresponding video.

After the movable vise assembly is assembled, insert it into the fixed pipe of the larger diameter and screw the other end of the lead screw into the nut of the second flange. To connect the lead screw with the wrench, a nut or washer can be welded to its end protruding from the side of the movable pipe, into the holes of which the wrench will be passed.

The clamping jaws of such a vice can be made from pieces of rectangular pipes that are welded to the moving and stationary parts. To give the structure stability, two supports are welded to the bottom of the fixed pipe, which can be angles or rectangular pipes.

The inner tube can also rotate during the rotation of the lead screw, which makes the use of such a vice very inconvenient. To prevent this from happening, a longitudinal slot can be made in the upper part of the stationary pipe, and a fixing screw can be screwed into the movable pipe, which will move along this slot and prevent the moving part from rotating.In many photos of homemade vices of a similar design, devices are presented, the movable and fixed parts of which are made of pipes of a square or rectangular profile. The use of such pipes also avoids rotation of the movable part of the vise.The vice of the described design, by V. Legostaev, belongs to reliable and effective clamping devices, easy to maintain and repair, which makes them very popular with home craftsmen.If you do not plan to heavily load the vice, then it is quite possible to make them from wood according to a simple scheme

The simplest construction of a homemade joinery vice consists of the following elements:

a body made of a solid wooden block, which also serves as a fixed clamping jaw;
movable sponge from a wooden block;
cylindrical metal guides along which the movable jaw will move;
a lead screw to move the movable jaw;
a knob by means of which rotation is imparted to the lead screw.

Carpentry vice device

The body of such a vice, on which the metal guides are fixed, is attached to the surface of the workbench using long screws or bolts. Both the body and the movable jaw of the clamping device need to make three holes - for the guides and the lead screw.It is best to drill such holes in both bars at the same time so that they are located exactly relative to each other.

Securing the vice from the bottom of the workbench

After the guides are fixed in the housing, a movable clamping jaw is put on them. Then a screw is inserted into the central hole of both bars, onto which a nut is screwed from the back of the body. On the second end of the screw, which protrudes beyond the front surface of the movable jaw, it is also necessary to screw and weld the nut. To fix the drive screw on the front end of the spindle, a hole of the corresponding diameter is drilled in the screw (or a nut is welded to it).

The photo shows the principle of assembling such a vice.

Such a vice works as follows: while rotating, the lead screw is screwed into a nut fixed on the back of the support, thereby attracting a movable clamping jaw to it.

The vise is secured to the workbench and ready to go

One of the main tools in any workshop is a vice. At first glance, this is a fairly simple tool, but in fact, with the help of a vice, you can perform a fairly large number of operations. There are a huge number of varieties: carpentry, locksmith, chair, cross. It so happens that the vice may become unusable. In this case, you can make a vice with your own hands.

A vice can be seen in any carpentry workshop. It is often necessary to clamp parts in order to grind them or simply glue them together. Homemade vices can cope with these tasks, which can be made with your own hands, and the price of such a product will be quite low. Often the jaws at the vise are made of soft wood to prevent damage to the part being clamped.

For convenience, the vice can be screwed to the workbench. In the fixed part, it is necessary to fix the furniture nut, into which the hairpin will be screwed, which, in turn, will move the movable mechanism. A washer must be rigidly attached to the movable jaw, and the knob itself must be attached to the handle. As for the sponge tips, they can be made from pieces of plywood.

If you need to assemble a carpentry vice with your own hands, then this option is considered optimal.

First, you need to mark all the parts, then cut out three identical bars (the longer the length of the bar, the larger the product can be clamped). The bed can be made from thick planks or 3 pieces of plywood. Drill two vertical holes in two fixed blocks. Drill a hole in one of the bars for a pin, which will act as a clamping mechanism. The next step is to install the nut into the timber.

At the end of the hairpin, you need to weld a small rectangular patch and drill 4 holes in it for fastening.After that, screw the pin into the fixed jaw and screw its end to the movable jaw, and the structure itself to the workbench.

These vices are also called Moxon vices or bench vices, they are quite successful in clamping large-sized boards, plywood, and various panels. The advantage of this type is that they do not take up a small area in the workshop, but are made of wood.

The dimensions must be selected independently; do-it-yourself carpentry vice for a workbench can be made using a minimum of tools and material.

The construction looks like this:

For manufacturing, you will need two studs, four nuts, three boards. After the boards are prepared and cut to size, it is necessary to drill two holes in the fixed and movable part. Then, in the fixed part, insert the nuts into the drilled holes, having previously greased them with glue on both sides. A small nuance: the holes in the stationary part should be slightly smaller in diameter than the nuts themselves, in order to avoid the nut turning in the hole. First, you need to weld the studs with a knob for convenience or make a wooden handle. The base for the stationary part can be made in the form of a step. Screw the finished structure to the workbench with self-tapping screws or bolts.

If you often have to work with metal, then for these tasks you need a strong metal vise that you can make with your own hands.

In order to assemble a locksmith vice with your own hands, you need the following tools:

Welding machine.
Electric drill.
Grinder with a cleaning wheel.
A square to comply with the required angles.
Drills of various diameters.

In addition to the tool, you will need:

Steel channel with a diameter of 6 mm.
Sheet metal 5-6 mm thick, as much as possible.
Corner 70 by 70 or 50 by 50.
Twenty bolts and nuts.

If you have a 16 mm diameter pin, you can use it as a clamping screw that will move the moving part. It is rather difficult to make two nuts into which the screw will be screwed in, and besides, the rest of the parts are rather non-standard and it is rather difficult to find them, so it makes sense to turn to a turner.

Then weld the nut to the channel, this must be done coaxially.

The ends of the channel must be closed with a piece of sheet metal and a screw hole must be cut in the strip.

Using a grinder, cut two corners and a plate. Lean the corners against the channel on both sides and cover with a piece of sheet metal on top. You will get a kind of U-shaped design.

The bed can be cut from 7-10 mm metal and drilled four holes on each side, as well as 6 holes in the U-shape.

Weld one nut to the bed, and weld two metal stoppers on the sides of the nut.

From steel, you need to cut blanks for two jaws, movable and fixed. The stationary workpiece can be welded immediately.

Then weld the second workpiece onto the moving part. On the sponges themselves, you need to make a kind of heels of thick metal. They can be welded or bolted.

If desired, you can strengthen the jaws on both sides with corner gussets made of thick metal.

These vices are no worse than purchased ones, and a minimum of material costs will be required. By this principle, you can make another version of yews from a hand jack. The finished product can be painted to give an aesthetic look.

Anyone who uses a drilling machine probably knows how difficult it is to drill and at the same time hold a workpiece that just strives to scroll or fly off and injure the master. As a rule, in old machines there is no vice on the bed, which brings certain inconveniences. For more comfortable work, you can purchase a tool, or you can make a vice for a drilling machine with your own hands.

For a machine vise you will need:

Corner 30 by 30.
Threaded hairpin.
Stud nuts.
Small bearing.
If desired, you can paint the product.

The drawing looks like this:

First you need to saw off two corners. The size is selected depending on the dimensions of the drill bed. Cut two sponges out of thick metal with a grinder and make markings. Drill holes in them to attach the jaws to the base.

Take a piece of the angle piece and drill a hole for the stud. You can immediately weld on the bearing, as shown in the figure.

Opposite the mount with the bearing, weld a similar angle and drill a hole for the shaft.

Opposite the mount where the bearing is located, three nuts must be welded.

In order to make it convenient to twist the pin, you can weld a nut to its beginning, into which you can insert the knob. Homemade vices for a drilling machine are in no way inferior in design and quality to factory ones and are several times cheaper.

Most anglers prefer a homemade fly tying vise rather than a store-bought one. The device itself has a fairly simple design, which allows them to be made in a short time and without special tools at home. The most difficult step in making a vice is the jaws themselves. They are made of rectangular steel bar. In the finished jaws, two holes are drilled for attaching to yews and one for an adjusting screw. The holes must be tapped (M6) with a tap.

Next, you need to tighten both jaws with a screw. After tightening, disassemble the jaws and install the clamping screw, and choose the angle of dilution for yourself. On the lips, you need to make a small groove for the hook.

The yew support can be made from T-shaped or L-shaped steel bar. Sponges are welded to the end of one of the blanks. The bar must be welded to the support, and if you need to make the support adjustable, then a piece of trim pipe is welded to the workpiece, the diameter of which is equal to the diameter of the workpiece. It is recommended to make the length of the support about 20-50 cm high for more comfortable work.

If the vice has become unusable and there is no way to fix it, then you should not buy new ones right away, but try to do it yourself. Such a tool will serve for quite a long time and will cost several times less.

Our workshop "Varim Bai" performs repair welding of damage to various vices (locksmiths, machine tools and others) as well as various clamps.

The base of the movable vise jaw and the vise nut body are most often susceptible to destruction. The main reason why the vise fails is excessive tightening force and the use of the vise for other purposes, for example, for pressing in-pressing out bearings and various shafts. When the effort on the standard vise screw handle is not enough, a good pipe is usually used, and the force applied to this "extension" breaks the vise with a probability of 95%. Moreover, both the grandfather's Soviet vice (to which we have deserved respect for the fortress) and the modern "Chinese" ones are breaking.

There is an opinion that repairing a vice is a thankless task and they will not last long anyway. Yes, it is difficult, expensive and time-consuming to cook cast iron using TECHNOLOGY, but it is possible to make a high-quality repair of the vice. Good and big vices are expensive. We can restore your broken vice for a reasonable price (up to 40%) of the cost of new ones.

Below we give some examples of the work performed:
