Making a rack for a grinder with their own hands

Roasting machines (USM) – an indispensable hand tool. With their help you can saw, grind, cut almost any materials from wood to stone. But often arise tasks that require the use of machine park.

For example, when cutting pipes, profile or metal profile, quite ordinary is the problem of cutting a long vacuum on the segments of a certain length. At the same time, it is important that the ends of the segments were strictly perpendicular to the axial line.

When cutting a ceramic tile or bricks, observe the perpendicularity of the cut, holding the grinder manually, even more difficult. With a cut of fine and viscous material The slightest deviation of the tool from the cut line can lead to a jamming and tool breakdown.

In such situations, it is quite natural to do not buy a separate machine – it is usually economically impractical.

It is possible to expand the scope of applying a favorite hand tool, in any way rigidly fixing it.

Materials and tools

The first question faced by the homemade sample when designing a rack for the Bulgarian – what to do it. The answer to this question is elementary: what is, from that and do. If under hand there are water pipes – they will be useful for the manufacture of hinges and guides. If there is a metal corner – we bring the face from it.

The main and most complex knot of the pendulum cutting saw is the hinge node. It comes to him the greatest loads, while the pendulum lever should not be able to arbitrarily deviate left or right. Refer to the design of this node with the greatest attention. Ideal to use roller bearings. Pick up a couple of suitable sizes – and already “around them” build the rest of the construction.

It is best to make the fastening of the pendulum lever on the balls or roller bearings. It will provide the best accuracy and rigidity. But if there are no suitable finished products, it is quite possible to see the options for the homemade structures of this node.

If there are no finished bearings, pick up a pair of metal tubes and steel pins of suitable diameters. This will make not very high quality, but homemade bearings. For the “plywood” machine as a suspension of the pendulum lever, good loops used for fastening doors and wickets will fully come.

In any case, the pendulum lever itself is better made from a metal corner or metal profile. But the holder in which the ESM will be fixed will certainly be made from a wooden bar.

For reliable and tight fixation of the grinder in the holder of the bed, it is better to attach a soft and durable material. For example, leatherette. And press the ESM to the holder is more convenient than all flexible metal ties with a screw knot. Such widely used in plumbing and auto repair.

The bed is best made from a thick sheet of metal. Compromissions are possible, up to thick plywood, fixed on a wooden bar frame. It is good to provide on the desktop the possibility of fixing the stubborn angles under some standard corners to the axis of the cut. So we get a “troting saw”.

Do not forget to control the inclusion of the grinder on the machine in the usual way now will not work. Operator’s hand on control keys We can replace all the same screw screeds for pipelines. But the keyboard post control (which we will fix on the bed), the socket for inclusion in the chain of a fixed AVM and a wire with a fork of sufficient length for inclusion in the network of all the machine should be plucking.

If we have metal blanks at our disposal, connect them best welding. If you do not have such an opportunity, it is better to contact familiar masters of this case. Bolt connections over time are cleared and reduced all the advantages of a metal frame.

Of course, when making the machine, Bulgarian herself will come in handy. Cutting with its help workpiece for the rack, you can feel like a Munchhausen, pulling out of the marsh of myself for a pigtail.

Production options

Honestly, existing in many drawings of racks made by their own hands should serve more food for reflection. It is worth viewing to the design, standard dimensions of standard elements and general design principles. Then apply them in our particular case.

The fact is that the size of the design and individual nodes will be entirely dependent on what you have at hand. For a large corner car (for example, USM-230), it may be necessary to make a larger holder than specified in the drawing. This will necessitate to replace bearings and so on.

General principles are quite obvious. The simplest and most used machine is the transformation of the handmade grinder to a stationary pendulum saw. This design consists of a bed, racks and a pendulum lever, hinged on the rack.

Consider the options for manufacturing depending on the materials available.

Stanna from a rectangular profile

Very hard in itself, such a profile allows you to construct a hard and durable bed. More importantly, the pendulum lever made from such a material is almost no bent when working.

But the frame of the bed – it is only half. Over the frame, you must impose a “tabletop” – a plate on which the material processed will be placed under the grinder.

If the frame is collected from the metal, the best material for the desktop will be a metal sheet. However, the thick sheet of plywood or chipboard is also quite suitable. Just do not forget that directly under the disk of the grinder in the table top it is necessary to provide a fairly wide slot, providing a pass-through disk stroke through the cutting material.

Vertical rack is a very loaded node of the pendulum saw. The use of a metal profile will create a solid and hard design.

When using metal as a base element, the machine should be preferred by welded connections. Of course, metal products can be connected to bolts.

But such compounds do not provide the necessary rigidity.

Caria of pipes and shock absorbers

If plumbing pipes, a pair of car shock absorbers and a metal corner or profile – can be made of a remarkable tracing (it is “cutting”) a transverse horizontal carriage.

The pendulum node is still needed to bring the tool into the plane of cutting. But the carriage, moving along the pendulum lever, allows you to significantly expand the range of material sizes. Now you can cut off quickly and definitely not only pipes, profile and timber.

Horizontal carriage running allows you to carefully cut the leafy materials of such a width, which departure of the carriage we can construct.

To ensure smooth, but at the same time accurate carriage turns usually design complex rails with spring-loaded bearings. But you can use car shock absorbers. They have a very durable and accurate design. If you remove gas and liquid, excellent guides will turn out.

Rear shock absorbers VAZ have a row running near almost 200 millimeters. This will allow, for example, when fastening on the ISM-230 carriage, organize a line of cut line up to 400 mm. But even if you have a compact Bulgarian with a disk with a diameter of only 150 mm, you can still cut the sheets with a width to 200 mm. This is more than covered by most everyday tasks.

When designing a “guide – carriage” node, on the basis of car shock absorbers, it is necessary to take into account the fact that the shock absorbers themselves are quite thin and easily impaired. To the top lever of the pendulum, such “guides” should be attached to semicircular clamps. This will use water pipes.

Elements of wood

If there is no possibility to make the basic elements of the pendulum saw of metal, do not despair. Many structural elements can be made of wood. First of all it is a bed, a pendulum lever and the Holder of the USM.

The face can be made of any suitable lumber. Very good frames collected from solid and heavy wood bars of significant cross-section. They are durable and pretty heavy. This ensures the stability of the entire machine.

The bed, assembled from the oak bar with a cross section of 100×100 mm, of course, impressive. But it is too expensive. For the base of the desktop, thick bars of larch or even birch.

But for the manufacture of a pendulum lever, you can use noble varieties of wood, traditionally used in furniture production. Oak here will be quite appropriate.

Constructing a machine from a tree, do not forget about the overall rigidity of the design. Significant bed dimensions allow us to ensure the strength and stiffness of this part in the manufacture of not qualitative materials from.

Pendulum lever has a long, elongated design. If you do it from a tree, its geometry can be unstable when the temperature and humidity changes.

For this design element, it is better to use the so-called furniture shield consisting of several wooden elements glued together.

Details of plywood

An interesting solution of the problem of rigidity can be use in the wooden structure of plywood. The multidirectionality of the layer of veneer in this material gives a certain stability of plywood sizes. The fact that the product consists of a plurality of thin layers, connected by durable glue, provides strength.

Plywood is great for the manufacture of mills and desktops. When designing it is necessary to take into account that plywood is very strong and stable in the plane of the product. But the plane itself may experience deformations. Therefore, plywood products should be mounted on hard frames.

A good example of the design is the assembly of elements from many layers of plywood with intermediate sickness and tie bolts.

It turns out very durable, rigid and stable designs.

Safety technique

As with the handling of any electric tool, electrical safety rules should be followed. Cannot work in high humidity facilities. When installing the machine on the street, it is advisable to build over the workplace at least a temporary canopy to protect against precipitation.

Like any cutting tool, ESM, even fixed in the machine, requires strict compliance with safety. Completely unacceptable work without protective casing around the disk. As well as the use of protective glasses or transparent shield.

Many are neglected with gloves – and quite in vain. Sparks flying out from under the saw stone, only seem small and non-hazardous. Abrasive and processed material crumbs fly as bullets and can penetrate deep under the skin.
