Homemade wood turning and copying machine with your own hands

Lathes and copying machines are used to make many identical parts, for example, balusters for stair railings, fence posts, etc. You can make a functional design with your own hands, using devices that are unnecessary on the farm.

Making a lathe

homemade turning and copying machine

The most primitive model of a lathe is made from a conventional drill. But this is not the only solution. Main parts of the future device:

• bed;
• front and rear pillars (headstocks);
• electric motor;
• master and slave centers;
• tool rest.

The bed is the base for placing all elements and mechanisms. Therefore, it is made of thick timber or metal. The headstock is securely fixed to the base; the part will be attached to it. The front pillar houses a device that transmits movement from the electric motor to the driving center and then to the part.

The rear post (headstock) moves along a guide on the bed; it holds the free end of the workpiece. A tool rest is placed between the headstocks. The headstocks must be positioned strictly along a single axis.

For a do-it-yourself machine, an electric motor with a power of 200 - 250 W, with a speed of no more than 1500, is suitable. If you plan to process large parts, a more powerful motor is required.

A faceplate is placed on the electric motor pulley, which secures large workpieces. The faceplate contains points on which the part is pressed. The opposite end of the part is fixed with a corner.

To turn a regular lathe into a copying machine, an additional device is required - a copier.

Copier for lathe

The basis of the copier will be an unnecessary manual router. It is placed on a surface made of 12 mm plywood, the size of the platform is 20 x 50 cm. Holes are made in the platform for fasteners and cutters, and stops are installed - bars for fixing the cutter. The router is placed between the clamps and secured with a pair of large nails.

The remote part of the platform moves along the frame along a guide - a pipe. Its ends are fixed in wooden blocks. The bars are attached to the frame with self-tapping screws. When fixing the pipe, you must use a level and align the axis of the pipe with the center of the machine. Before installation, a pair of bars with holes are put on the pipe and can be easily moved along the guide. A platform on which the router is placed is attached to the bars.

The second important element is installed with your own hands directly on the lathe - a block in a horizontal position on which the templates will be attached. A 7 x 3 cm beam is suitable; it is attached to the vertical stands with self-tapping screws. The stands are screwed to the frame. The top surface of the block must clearly coincide with the axis of the machine.

When the copier is not in use, the block is dismantled, the platform with the milling cutter is moved back and the machine turns into a regular lathe.

The stop is made of thick plywood and is attached to the work surface. In fact, the stop plays the role of a copier in this design. It is fixed vertically and fixed to the end of the working surface on a transition beam made of wood. The copier can be removed, it is installed on the stand with self-tapping screws. The stand must be fixed firmly, without the possibility of removal.

The templates are made of plywood and are screwed to the front surface of the block using self-tapping screws. The upper surface of the beam should be aligned with the axis of the template.

Disadvantages of the proposed design

• The working surface with the router has to be moved with both hands, since during operation it warps and jams;
• You can only copy fairly simple elements, for example, it is impossible to repeat twisted patterns on posts;
• to move the cutter it is more convenient to provide a screw drive;
• It’s better to replace the cutter with a circular saw; such a device will be more universal.

Wood lathes

The design of woodworking lathes is similar in basic parameters to metalworking equipment. They also have a front and rear headstock, a caliper, and a spindle with cutters. The purpose of the equipment depends on its weight, equipment with additional devices and automated control systems.

Wood lathe

Construction of a woodworking lathe

The design of a wood lathe differs from that of metal lathes in that it does not require a cooling system; therefore, there is no coolant supply system. The power of a manually controlled woodworking lathe is less, but it has adjustable rotation speeds. To work on manually operated wood lathes that are not intended to produce one type of product, special devices are used - cutters and a removable faceplate.

The faceplate serves to securely secure material of the maximum permissible diameter, and the cutter is used for manual work on equipment that does not have a permanently installed support. They are more often used for making simple blanks for painting, turning cuttings needed on the farm for shovels, ax handles and other household utensils.

The school wood lathe gives a complete idea of ​​how you can make household items and beautiful souvenirs. A machine operating at low speeds will allow the novice master to understand the basic operating principle of all turning units and mechanisms. The skills acquired at school will help you master more complex CNC turning equipment.

One of the most common equipment in mass production in woodworking shops is a wood turning and copying machine. For its operation, devices are needed - stencils, according to the outline of which the outline of the object will be created.

Classification of woodworking machines

Many types of equipment are used in the woodworking industry. The main characteristics by which classification is made are the technological process and design features.

Equipment of different designs for performing the same operations may differ in operating technology.

• Processing 1 or many items;
• Number of threads;
• 1-axis or 4-axis;
• By the number of spindles;
• Along the trajectory of movement of the processed material;
• By the nature of the presentation.
• By cyclicality.

Wood lathe with copier

The scheme of operation on a turning and copying machine is as follows:

1. At the top of the frame, a stencil made of wood is installed on special fasteners - a copier.
2. The rolling roller moves along the outside of the copier.
3. By connecting the roller to the cutting tool using a rigid fastening method, the cutter accurately transfers the movement of the roller along the copier to the wood. Where there is a recess on the copier, there will be a convex element on the wood, and the protrusion on the stencil will appear as a notch in the finished wooden object.

For the production of identical elements of wooden decor, a machine with a copier is the most convenient solution.

A lathe, on which processing is carried out using hand tools: rayer, meisel, scraper, is not particularly accurate. When making several similar parts from wood with the same density characteristics, you have to rely only on the skill of the turner and his eye, but it is still very difficult to give a 100% guarantee that they will be identical. The use of different types of wood in the production means that cutters and devices will need to be different from each other.

The wood turning and copying machine is distinguished by the accuracy of reproduction of the stored data. The copier is a kind of CNC prototype. One copier allows you to make identical things an infinite number of times, which is necessary for the manufacture of balusters for railings or legs for cabinet furniture sets. In workshops where production is on stream, it is more advisable to use CNC-equipped copying machines.

When working with wood, there is always a manual process of bringing the part to perfection using sandpaper. Grinding is carried out at the stage while the object is secured between the lathe heads. Rotation is programmed at lower speeds than those at which cutting was performed.

Lathes are used to turn oblong-shaped wooden elements. The workpiece is mounted on a spindle with approximately equal weight distribution. To do this, holes are drilled in the center of the end ends of the wooden workpiece - this is necessary so that the rotation of the shaft is uniform. Most often, cylindrical wood or timber with planed corners are used. Cutting is carried out not only on the external, but also on the internal surface of the workpiece. The shapes of finished products can be complex, conical, cylindrical - symmetrical relative to the center of the product.

A desktop wood lathe equipped with a computer programming system has high precision in reproducing complex designs. It can be used to create very complex carving elements.

Classification

Lathes are divided into:

• center ones with mechanized feed. It is possible to perform work on this equipment using hand-held cutting tools (when installing a special tool rest on the frame). An oblong piece of wood is held by a spindle and a movable tailstock. The longitudinal feed of the caliper is mechanized. These machines can be used to work with a copier. When working with short, light workpieces, the tailstock fastening may not be used. During processing inside The wooden part is fastened with a faceplate. The moving elements in the operating mode on these lathes are the cutters moving along the piece of wood being processed and the rotating spindle.
• Lathes are used to produce parts on a flat, wide wooden base. Beautiful multi-level carvings, bas-reliefs, high reliefs - this is what can be produced on machines that work with a wide faceplate, on which the workpiece is mounted. Work is carried out only on the front part of the part. The rest of the revision will be done manually.
• round-sticks process wood, giving it a shape with a round cross-section. When working on this equipment, the workpieces do not rotate or move. The only moving parts of the machine are the heads with the cutters. There are also machines in this group for processing long products. Then they will feed the workpieces with rollers under the cutters.

Shaping wood occurs by rotating the material being processed and using a cutting tool.

Device and equipment

Woodworking lathes differ in the type of support feed and the shape of the items being manufactured.

1. Wooden blanks not exceeding 40 cm in diameter and 1 m in length, 60 cm, are processed on a lathe with a tool rest.
2. Power-feed lathes are designed to handle wood workpieces with the same size limitations as hand-cutting lathes.
3. The device for disc-shaped wooden blanks has the ability to place parts up to 3 m in diameter on the working surface. The thickness of the wood is limited by the parameters set by the machine manufacturer.

Diagram of a lathe with a mechanical support feed, equipped with an attached frontal device:

• bed on 2 pedestals;
• headstock and tailstock;
• calipers;
• spindle rotated by a 2-speed motor;
• V-belt drive connecting the 3-speed gearbox to the engine;
• a pulley mounted on the spindle drives the longitudinal slide;
• the cutters are mounted in a rotating holder;
• the main - transverse and additional - longitudinal supports set the direction of movement of the cutters.

When working with hand cutters, it is necessary to install a tool rest on the guides of the frame. At this stage of processing, the support is retracted outside the working area until it stops.

Accessories for lathes Tools for wood lathes

The head device also has a rotating holder. This device is used for processing workpieces with a diameter of up to 60 cm, fixed on one side to a faceplate connected to the spindle, and fixed by the tailstock of the machine. When processing a short workpiece, the clamp may not be used, which simplifies internal processing of parts.

The speed of cutting the edge of a tree at different points is different, which is determined by the distance of the cutter from the axis of rotation. This is most clearly seen when working with a copier. The spindle speed is determined by the diameter of the wood material being processed and its strength.

How to make a copier for a wood lathe?

In order to make a copier for a wood lathe, you will need the following components that will be necessary in the manufacturing process:

• electric motor with a power of approximately 800W;
• metal shaft with a nozzle for changing the saw blade;
• metal profile of square section, metal corners;
• wooden sheet;
• furniture guides;
• metal marker;
• fastening materials.
• welding machine, grinder.

First you need to make metal guides.

They will allow you to move the entire copier structure in the longitudinal plane. In this case, two metal corners are used, which are turned over with the sharp side down. The corners are welded together into pieces of metal profile.

This approach allows us to provide the necessary mechanical strength and eliminate the possibility of the guides bending under the weight of the copier. In practice, any other metal profile can be suitable for the manufacture of longitudinal guides, the main thing is that its mechanical parameters allow it to carry out the assigned tasks.

In this case, a wooden box and board were used to make the base of the future copier. The board is sized to allow movement inside the box in a perpendicular plane.

For fastening and subsequent movement, ordinary furniture guides are used.

The engine is attached to the board on top. In this case, the power of the electric motor is 800 W and the speed is 3000 rpm. Depending on your needs, you can use a motor with other parameters.

Next, the shaft should be secured to the board at such a distance that the belt drive normally connects two pulleys, one of which is located at the end of the motor shaft, and the second on the horse shafts of the saw blade. A homemade shaft with one bearing is used here.

A U-shaped structure must be made from a square metal profile. In the upper part of the U-shaped structure, a special metal holder of square cross-section is welded to the horizontal bar. The length of the holder must be less than the length of the marker.

To secure the marker in the holder, holes are drilled on the top plate. A metal nut is welded onto each hole and a bolt is screwed into it. Two bolts will be enough for reliable fixation. The adjustable marker is very convenient when changing saw blades of different diameters.

Simply install the desired disk and use a plumb line to align the marker with the edge of the disk. The marker mount must correspond to the position of the saw blade in all planes. This allows you to simply move the marker along the prepared template to coaxially move the disk along the rotating workpiece.

The entire machine is assembled from two channels and metal corners for the sheath. On which a motor is mounted that rotates a wooden piece. In this case, an electric motor with a power of 1200 W is used.

You can use an old frame from some other machine as a frame. For ease of operation, it is better to place the engine on a removable metal plate, which allows you to move the structure with the workpiece, both in the vertical and horizontal planes.

The clamping head is made of four metal plates in the shape of rectangular parallelepiped. Two nuts are welded into the end walls of the clamping head, into which a metal screw is screwed. A cone with a cartridge is installed at the end of the screw.

In cases where you need to eliminate the possibility of contamination of the surrounding space with sawdust from the operation of the machine or to minimize the percentage of contamination, you should make a hood.

The saw blade is covered with a metal casing, to which a flexible corrugated hose and a compressor unit are connected to create an air flow of a given power.

Do-it-yourself copying lathes for wood (video, drawings)

It is not so difficult to make a copier and a wood lathe with your own hands if you have an idea about assembling such equipment yourself. The copier function itself can be a pleasant addition to the machine, since it enables mass production of identical products. You don't have to cut out each piece based on the previous one. Using a copier, a lathe will do everything in the best possible way.

Lathe

Photo of a do-it-yourself wood copying machine

Before making a copier for a wood lathe, you first need to make the turning unit itself. Many craftsmen make simple models based on a drill. These large woodworking industries use professional equipment. At home, you can get by with a homemade copier and machine.

Standard lathe includes the following required elements designs:

• Stanin;
• Two headstocks (front and back);
• Electric motor;
• A pair of centers (master and slave);
• Stop for cutting tools.

Drawing of a wood copier machine

Let’s look at the design in more detail to make it easier for you to make a homemade wood lathe with a copier without unnecessary help, but only with your own hands.

1. Bed. The bed serves as the basis for installing all the necessary components and mechanisms of the lathe. Therefore, to make a frame with your own hands, it is better to use metal or a thick wooden beam.
2. The front pillar, also known as the headstock, is mounted on the base. The headstock is used to fasten the part to be processed. In the headstock there is a device that transmits rotational motion from the electric motor to the driving central axis, and then transfers it to the workpiece.
3. The tailstock moves along the frame using guides. The job of the back post (or headstock) is to hold the free end of the wood piece being processed.
4. Between the two headstocks there is a stop necessary for the cutting tool. In this case, it is important to ensure that the headstocks are located in a single axis.
5. The electric motor can be selected in a power range from 200 to 250 W. For a home lathe with a do-it-yourself copier, this power is quite enough. But if your plans include processing large items, you will need a more powerful engine with a speed of about 1500 or more.
6. A faceplate is mounted on the pulley of the electric motor of the future lathe. It will fix large-sized products. The faceplate has sharp elements on which the wooden blank is hammered before processing. The corner is responsible for fixing the opposite end of the part.
7. To turn a regular turning unit into a wood copying lathe, you need to equip it with an additional device - a copier.

A homemade wood lathe with a copier is no different complex design, so it’s quite possible to do it yourself.

You can use a device that is used by woodworking enterprises. But they are designed for large-scale production. Therefore, it is preferable to make a woodworking copier with your own hands if you already have a ready-made homemade turning device.

But how exactly do you make a suitable copier? Follow the instructions and additionally watch the video tutorial. Based on them, you can easily retrofit your woodworking lathe with an effective copier.

1. Take a hand router as a basis, which will become an excellent platform for making a copier.
2. The router is mounted on a surface made of a 12 mm thick plywood sheet. The platform is usually made with dimensions of 20 by 50 centimeters.
3. In this plywood area, drill several holes needed for the cutters and fasteners.
4. Next, stops are installed on the site. These are ordinary wooden blocks that will hold the cutters in place.
5. The router is installed between the clamps. It is advisable to secure it using self-tapping screws or large nails.
6. The guide pipe will move the remote part of the plywood platform along the frame. Its ends are fixed in wooden blocks.
7. The bars are mounted on the frame using self-tapping screws.
8. When attaching the guide tube, be sure to use a level to ensure perfect alignment of the guide axis and the center of the machine.
9. Before completing the installation of the guide pipe, two wooden blocks with holes should be placed on it. It is extremely important that they move easily along the guide.
10. A platform with a router placed on it is fixed to the bars.
11. Next, you need to make an equally important element of a homemade copier-lathe - this is a wooden beam located horizontally, which is mounted on the machine itself. This block will secure the templates. Use a beam measuring 70 by 30 millimeters. Secure it to vertical stands using self-tapping screws. The stands themselves are mounted on the frame. Make sure that the top surface of the horizontal block coincides with the axis of the turning device.
12. If you do not use a copier at certain stages of work, this block is simply removed, and the platform from the routers is moved back a little. This allows you to turn the copy-lathe into a regular turning unit.
13. To make the stop, use thick-walled plywood, which is mounted on the work surface. In fact, the stop will act as a copier in the machine design we presented.
14. The stop is fixed in a vertical position and mounted to the end of the working surface on a transitional wooden beam. The copier can be easily removed if necessary. It is held on the stand with self-tapping screws. In this case, the stand should be installed securely so that it cannot be removed.
15. The templates themselves are made of plywood. They are mounted with self-tapping screws on the front surface of the block. Be sure to align the upper surface of this wooden block with the axis of the template used.

Design flaws

A copier like this is an excellent solution for a home lathe used for woodworking operations. But in addition to significant advantages, the design has certain disadvantages.

• You will have to use two hands to move the work surface. This is due to the fact that during operation the surface with the router will jam and warp periodically;
• Using such a copier it is impossible to make complex elements. Therefore, you will only use it to copy the simplest elements;
• To move the cutting tool, it is still better to reconsider the proposed design and use a screw drive. It demonstrates higher efficiency;
• Instead of a milling cutter, it is preferable to use a circular saw. Thanks to it, your machine will become functional and multitasking.

It is quite possible to make a copying woodworking unit with your own hands. This will require a little time, certain skills and desire. For comparison, the price of a factory lathe copying device is about 10-20 thousand rubles.

Be sure to read these materials:

A variety of equipment, including machines, can be used to work with wood. Through the use of such equipment, it accelerates the process of mechanical processing of wooden blanks. A wood lathe with a copier is in great demand, which greatly simplifies the execution of assigned tasks: making furniture legs, door handles and balusters.

Many people decide to buy and install lathes in their own workshop because of their possible use in the manufacture of cylindrical products. There are quite a large number of different models; they can be divided into several groups:

1. Classic equipment, when the workpiece is located in a chuck or faceplate. A cutter is used as a cutting tool. The workpiece can rotate at different speeds. However, the equipment is not suitable for mass production.
2. Copying machines can be used to work from a template. By using a template, you can simplify the task of manufacturing similar products. For small-scale production, a manually operated machine is suitable, as it is low cost and easy to use.
3. Milling machines are extremely common today. This is due to the fact that they are widely used in the production of cabinet and flat parts made of wood and metal. There is also turning milling machine woodworking, which can be used to perform various operations.
4. Models with numerical control. In mass production or the manufacture of expensive products, equipment that has a CNC unit can be used. However, the use of a copier significantly reduces the cost of the product.

For a wood lathe, it has very attractive characteristics, due to which they began to be installed in private and other workshops.

Classic design

Industrial machines have a rather complex design, especially CNC versions, which can carry out processing automatically. The required product can also be obtained using copying equipment. The classic design is represented by a combination of the following main components:

A homemade copier for a wood lathe also allows for high-quality processing of workpieces.

DIY making

Industrial versions of machines are expensive. That is why many are considering the possibility of assembling the machine with their own hands. Recommendations for carrying out the work are as follows:

Most attention is paid to the production of the copier. This is what distinguishes a lathe from a copying machine.

Creating a copier

The copier is used to produce similar products. Due to its use, the productivity indicator is significantly increased. Among the features associated with creating a copier, the following points are noted:

The template is made of plywood and is screwed to the front surface of the beam. The upper surface of the previously installed beam is aligned with the axis of the template.

Disadvantages of the device in question

A homemade copying machine has a fairly large number of significant disadvantages. An example is the following information:

That is why it is recommended to install industrial machines to establish the production of complex wooden elements.

Wood cutting machine Proma DSL-1200

The model in question is intended for processing wooden products that can be used as decorative elements. Distinctive feature experts call the design the presence of two incisors:

This machine model can be used to work with large workpieces. For this purpose, the structure is equipped with a structure that is mounted on rods that act as guides. The installed faceplate allows processing multi-faceted products.

Main characteristics of the model:

The disadvantage of this proposal, like many others, is the rather high cost.

Copy model CL-1201

To produce wood products, a machine model CL-1201 or CL-1500b can be used. The first version has very attractive performance characteristics:

In addition, the manufacturer paid quite a lot of attention to the degree of protection of the machine from exposure environment. For example, the engine has a protection system against overheating or overload, all electronic parts are also protected from moisture and dust.

The only but significant drawback is the high cost of the proposal. A homemade design will cost several times less.

Copier for wood lathe with manual router

We suggest that you make your own copying device with minimal time investment; the machine can be put into “industrial production” of turned parts by the evening. The “cutting tool” will be a manual milling cutter; the technical characteristics of the parts being manufactured depend on technical characteristics wood lathe. Despite the fact that the copier is made using plywood, it can produce up to hundreds of products from one copier, you will agree that this quantity is quite enough to fulfill most wholesale orders.

The device does not look exactly “attractive” from a design point of view, but we did not set such a task for ourselves. We tried to make our “equipment” as simple to manufacture and more or less reliable as possible. Which is what happened in the end. How is a copier made? Let's get to know him better.

Copier device

An ordinary hand-held milling cutter is used for the cutting tool; the specific model does not matter. Place the router on the support platform, our platform dimensions are 500×200 mm, made of sheet plywood 12 millimeters thick. You can slightly increase or decrease the linear parameters of the site depending on the size of the hand cutter. On the site, make holes for the cutter to exit and holes for installing mounting bolts. In order to completely eliminate unauthorized spontaneous movements of the cutter during operation, we advise you to install additional stop bars around the perimeter on the site, secure the bars with self-tapping screws, the length of the screws is selected taking into account the thickness of the fixing bars.

The router must be installed between the stop bars, check the reliability of its fixation, any vibrations are completely eliminated. The far end of the platform should “ride” along the pipe the entire length of the wood lathe, we used a Ø 25 mm pipe, you can use other pipes for making. The main thing is that they can withstand the weight of the router without bending, that they are absolutely flat and have a perfectly smooth surface. Secure the ends of the pipe with two wooden blocks; in our case, 80x35 mm blocks were used. Screw the bars to the body of the lathe using metal screws; you do not have to cut threads for the bolts. If your machine design does not allow you to fasten the bars in this way, then solve this problem in your own way.

Installation of the main structural elements of a homemade copier

Strong advice - do not rush during the manufacture of equipment; turned parts for a copier do not forgive even the slightest violations not only of technology, but also of the location of the working axes. It follows from this that the axis of the pipe along which the milling cutter will move must be perfectly parallel to the axis of rotation of the lathe. We naturally found that the axis of the pipe coincided with the axis of the machine, but this condition is not necessary. The main thing is that the cutting tool of the cutter in its lowest position coincides with the axis of the machine, and this parameter can be adjusted by the level of the copier.

The pipe is fixed in the blind holes of the bars; before fixing it, you need to put two bars on it, on which the bearing platform of the router will be installed. An important condition is that the bars for the platform should slide easily along the guide pipe, but wobbling is prohibited. Check this parameter and, if necessary, manually lap the pipe and bars. Then attach the router support pad to the bars and install the router on it. Check the smoothness of sliding again, making sure that there is no wobble at all. Don’t be afraid of such “strict” requirements for gliding quality. If you have a pipe with a normal surface and completely flat, then achieving smooth sliding is not difficult.

Installation of a horizontal bar

This is the second “working” element of a homemade copier; in terms of installation accuracy, you must comply with all the above requirements. The profile template of the parts is attached to the horizontal bar. A 70x30 mm block is quite suitable for manufacturing; it is attached with self-tapping screws to vertical wooden posts; fix the posts in any convenient way to the lathe bed. The upper edge of the horizontal bar must be parallel to the axis of the machine and be flush with it. If the copier becomes temporarily unnecessary, the block can be easily removed, the mounting platform for the router tilts to the rearmost position and the wood lathe can be used for its intended purpose.

Attach a vertical stop to the working platform of the router; we made it from thin plywood; you can use more durable materials, even metal. This part will move along the copier during turning and set the spatial position of the cutter; fasten the copier as firmly as possible. There is a direct relationship in terms of thickness: the thinner it is, the more accurately the dimensions will be taken from the template. But there is another dependence - too thin a copier makes it difficult to move the device along the template, choose the golden mean. The height of the copier must be adjusted after the final assembly of the machine; during adjustment, all the listed conditions must be observed. One more thing. If you have a copier made of plywood, then you need to make it removable; this will allow you to quickly replace a worn-out copier with a new one while turning a large number of similar products.

How the template is made

There's nothing new here. Draw the outline of the part to be turned on a strip of plywood or OSB board, check all the dimensions again and carefully cut out using an electric jigsaw. The edges must be sanded to remove nicks and irregularities. Attach the template to the horizontal rail with self-tapping screws; when fixing, observe all installation dimensions.

Some features of turning

You will have to move the device only with two hands, otherwise it may jam on the pipe. Another problem is that the radii of curvature of turned parts are limited by the diameter of the cutter; this must be kept in mind when choosing the profile of turned parts. Practice shows the dependence of the feed speed on the diameter of the cutter: the smaller the diameter of the cutter, the less the feed should be and vice versa.
