TABLE OF CONTENTS

1. Relevance of the topic.

Rationale for the choice.
My choice of product is justified by the fact that I really like furniture, I like to repair it. So I decided to make my first product, a baby chair. There are a huge number of shapes, sizes and designs of baby chairs, but I decided to make my own creation. I created the form myself. At first I drew a sketch, thought out all the dimensions, and then began to carry out the drawings, after which I started the manufacturing process.
Goals and objectives.
In the manufacture of my product, I adhered to the following goals and objectives.
Goals:

Aesthetic look.
- Manufacturability.

Practicality.
Tasks:

Improve your knowledge of wood finishing.
- Improve your hand tool skills.
Originality and practicality.
My product has practicality, it is original in that I made it myself: I came up with the shape myself, drew up the documentation myself, prepared the material myself, cut out the contour myself, connected and adjusted all the details and elements myself. The finished product looks good baby chair or a gift. Manufacturing costs are not very high.

2.Historical reference.

The history of the chair goes back to ancient times. Even the ancients realized the need for this item, on which you can comfortably settle down. The chair of a primitive man was a piece of a fallen tree, or a large stone. Chairs, like other luxury items and furniture, were finished with gold and made from especially expensive woods. Every home has chairs. Their design at different times corresponded different design. These were massive chairs made of precious wood, children's chairs, chairs for the sick and the disabled. Time makes its own adjustments, at present chairs are made of light metal, plastic, as well as well-known computer chairs. At all times, people have brought something unusual to the design and design of chairs.

3.Requirements for the product.

The finished product must be:

necessary for use;

have a pleasant appearance;

convenient to use;

durable and high quality.

4. Bank of ideas. Choice of option.

Consider some options for children's chairs.

Of the presented models of children's chairs, option No. 1 seems to me the most suitable. That is what I will be doing.

5. Justification for the choice of materials.

I will make my chair from pine wood.Pine has soft wood. Plus, it's lightweight yet durable. It can be easily processed with a chisel, saw or cutter. Almost any product is cut out of it. In addition, I will need 6 dowels, glue, stain and varnish.

6. Choice of equipment, tools and fixtures.

To make a chair, I will need the following equipment and tools:

Electric jigsaw;

Frazier;

Hacksaw;

Drill;

Pencil;

Ruler;

4. After work, disconnect the power tool from the power source.

9.Economic reference.

In order to calculate the cost of making your product, you need to know the cost of all materials and electricity spent on its manufacture.

I did not take into account the costs of:

Depreciation of equipment, as he worked in a school workshop;

Electricity, as they worked during daylight hours;

Salary, as he did everything on his own;

I also made the dowels myself, so I did not take into account their cost.

Determine the cost of the feeder.

10. Ecological justification.

Natural wood products are environmentally friendly. They do not harm the environment and are fully subject to recycling. A small environmental problem can be created by the use of furniture varnish, but very little was used in the manufacture of this product. Therefore, we can conclude that the designed product turned out to be environmentally friendly, does not cause allergic reactions in humans and does not harm the environment.

11. Evaluation of work performance.

I believe that the manufactured chair meets all the requirements for it. It is small-sized, comfortable, durable, has a pleasant appearance and will fit well into the interior of a children's room. I think that I did well with my goal.

The stool is made of pine wood. Manufacturing technique - artistic wood processing. The product is varnished. The design of the product is reliable and stable. The seat has rectangular shape. The legs of the stool are not high, so it can be used as a footstool, and so that you can sit when you peel potatoes, for example, or put on your shoes. This beautiful, original chair can decorate any kitchen and be useful.

Selection and justification of the project topic

The house in which we live, work and relax should be comfortable, cozy and, of course, beautiful. To achieve this, there is no need to spend a lot of money, a lot can be done with your own hands.Wood for me is the most accessible material, which gives a wide opportunity for creative activity in the manufacture of original products in a school workshop. I have already made a few for my homedecorative items: cutting board, bookshelf, shoe rack.Unusual handmade products will not only bring warmth to the house and decorate the interior - they will give a piece of a fairy tale that will stay with us forever.

After studying the needs of my family, I came to the conclusion that we need a low stool in the kitchen.

I put in front of me target :

design and manufacture a beautiful and inexpensive stool from wood.

While working on the project, I decided the following tasks:

to develop an economical, technological, durable and reliable design of wood products;

develop a simple technological process for making a stool based on the studied wood processing technologies using equipment that I already know how to work with;

produce a product according to the technical documentation for a limited time.

When choosing a project topic, I took into account:

my skill level.

Necessity for me, work done.

The cost of purchasing materials and tools in the course of work on the project.

The amount of time required to complete the project.

Expected Result

So, the issue is resolved! I'm making a stool for the kitchen! That's just what? What to make the legs, the shape of the seat? What decor to use? On the Internet, I found several options for chairs that could suit me.

Having considered all the options, having studied their features, the need for materials and other components, it was decided: to make a stool with solid legs. You should get a beautiful, original product that can decorate any kitchen and be useful for many years.

Historical reference

Wooden art products are household items that organically combine beauty and usefulness. These include jewelry wooden houses - carved architraves, valances, skates on roofs; decorative elements in the interior - parquet floors, carved decorations of doors, ceilings, wall panels, etc.; furniture and lamps; household utensils - dishes, cutting boards; wooden toys and souvenirs (turned, carved, painted); clothing embellishments, etc.

Artistic products made of wood, in addition to expressive proportions, colors, shapes, often have some kind of decoration: an ornament or a revealed texture of the material. Modern artists of decorative and applied arts - folk, professional, amateur - in search of forms and means of artistic expression rely on the age-old traditions of national and world art.

Artistic processing of wood is one of the oldest crafts mastered by man. In our country, especially in Russia, wooden architecture, , furniture, various household items made of wood belong to one of the most important types of art and occupy a significant place in the national culture of the people.

Choice of material, tools, equipment

Having made a choice of the object of labor, I began to collect information about similar products manufactured by enterprises: materials used, sizes, types of designs, prices. For this purpose, I visited the shops, the market. But I did not find such a chair. Therefore, he himself chose the material, developed the design and method of manufacture.

Choice of wood. In the manufacture of this product, I used pine.Pine is the cheapest and most pliable material; bars and boards from it are used in the manufacture of many products.

The choice of self-tapping screws for assembly and varnish. The stool is intended for use inside a heated room, so I decided to use self-tapping screws to connect its parts..

Coating with varnish allows you to protect the surface of the product from moisture penetration and decay. I chose alkyd varnish brand PF-283

Tools and equipment:

1. When making a stool, you need hand tools: hacksaw, hammer, center punch, mallet, planer.

2. The seat of the stool and the legs are shaped, so it is better to cut them electric jigsaw.

3. Drilling holes is convenient and fast can be done on drilling machine.

4. For decorative finishes the edges of the seat of the chair and the legs, a hand mill is used, since it is difficult to do it manually and will take a lot of time.

Environmental justification of the project

Natural wood products are environmentally friendly. They do not harm the environment and are fully recyclable. The use of production waste in the manufacturethe tsarg of the chair will avoid their disposalwhich contributes to pollution environment. The varnish has a state certificate and is approved for use.

During the manufacture of the product, the following work may be dangerous:

Drilling, sawing, surface cleaning (wood dust);

Decorative finish (varnish smell)

If the safety regulations (work uniform, goggles, respirator, ventilation) are followed, these hazards are very small.

The product is also safe to use. Therefore, the manufacture and use of this product will not lead to violations of the ecological environment of society.

Economic justification of the project

Price utilities(energy costs when working with an electric jigsaw, milling machine, drilling machine) Total operating timeis approximately 2 hoursequal to the consumption of electrical energy in 4 kW. 2.26x 4 \u003d 9.04 rubles.

The cost of depreciation of equipment is not significant, it can be neglected.

The cost of a stool: 149 rubles

Conclusion: having studied the market conjecture, I came to the conclusion that the price of my product is significantly lower than the market price. Therefore, it is profitable to make products yourself.

3. Identification of the main parameters and limitations The product must meet the following requirements: 1. The product must be made accurately. 2. The product must match the chosen style. 3. The product must be beautiful. 4. The product must be durable. 4. Theoretical information The product that I decided to make, as indicated above, should be neat, beautiful and durable. I decided to make a stool from wood. In this case, it is best to make from linden wood. Linden - refers to deciduous wood. Linden wood is valued for various crafts and buildings. It is used for the manufacture of furniture, drawing boards, barrel containers. 5. History and modernity The history of chairs goes back to ancient times. Even ancient people realized the usefulness and necessity of such a thing, on which one could sit down and relax. The chairs of the primitive man were a flat stone with jagged edges. Subsequently, people began to improve the chair, adding some details to it. Gradually he began to accept, albeit remotely, modern look. In later times, chairs decorated precious stones and made from expensive materials have become a luxury item. Royal chairs (thrones) were hollowed out from a huge block of marble, inlaid with diamonds and other precious stones, and trimmed with gold.

Hunters and fishermen also use chairs, and a wide variety of objects can play their role: boxes, even stones, logs, etc. Every home has chairs. Their designs at different times were different and corresponded to different ideas of people about beauty and convenience. These were the chairs different varieties wood, ranging from cheap pine to extremely expensive mahogany. There are also several popular modifications of the chair chair, rocking chairs, sofas, ottomans. And although they look different, their purpose is exactly the same. In normal wooden chair designs with four legs are most commonly used, but specimens with only three legs can be found. 6. Bank of ideas Having studied the theoretical material, the history of the emergence and development of the issue, it was decided to make a product using the woodworking technique, with which it would be possible to make a stool from wood.

Safety rules during work Safety instructions for manual processing of wood Before starting work kerchief. At the same time, hair should be carefully selected and the ends of the kerchief should be tucked in). 1. Check the availability of inventory (seat, brush, scoop), serviceability of the workbench (clamping boxes, sawing stop, clamping wedges, drawing devices). 2. Lay out the tools for individual use on the workbench in the strict order established by the teacher. There should be nothing superfluous on the workbench. During work

1. Clamp the workpiece (wood) securely in the clamps of the workbench. 2. Use the tool only for its intended purpose, serviceable, well adjusted and ground. 3. Perform technological operations (sawing, drilling, joining parts) on a workbench in designated places, using fixtures, stops and backing boards. 4. Do not allow the workbench to be cluttered with waste, shavings. Return the shared tool to the teacher in a timely manner. 5. Do not be distracted during work, follow the correct working methods. 6. In order to avoid injury, it is necessary: to clean the plows (planer, sherhebel, jointer) with wooden wedges; in case of damage to the tool during operation, immediately replace it. After completion of work 1. Hand over the rest of the materials, unfinished products to the duty officer or teacher. 1. Check the condition of the instruments and put them in the order set by the teacher. 2. Clean up your workspace using a sweep.

4. Theoretical information

The product that I decided to make, as indicated above, should be neat, beautiful and durable. I decided to make a stool from wood.

In this case, it is best to make oak wood.

Oak - refers to deciduous ring-vascular wood species. Oak wood is distinguished by high strength and hardness, resistance to decay, the ability to bend, has a beautiful texture and color. It is used in carpentry and furniture, veneer cutting and parquet production; in wagon-carriage-shipbuilding, as well as in agricultural engineering, in the production of riveting blanks for barrels.

5. History and modernity

The history of chairs goes back to ancient times. Even ancient people realized the usefulness and necessity of such a thing, on which one could sit down and relax. The chairs of the primitive man were a flat stone with jagged edges. Subsequently, people began to improve the chair, adding some details to it. Gradually, he began to take, albeit remotely, a modern look.

In more recent times, chairs adorned with precious stones and made of expensive materials have become a luxury item. Royal chairs (thrones) were hollowed out from a huge block of marble, inlaid with diamonds and other precious stones, and trimmed with gold.

Hunters and fishermen also use chairs, and a wide variety of objects can play their role: boxes, even stones, logs, etc.

Every home has chairs. Their designs at different times were different and corresponded to different ideas of people about beauty and convenience. These were chairs made of various types of wood, ranging from cheap pine to extremely expensive mahogany. There are also several more popular modifications of the chair - armchairs, rocking chairs, sofas, ottomans. And although they look different, their purpose is exactly the same.

The traditional wooden chair most commonly uses four-legged designs, but you can find examples that have only three legs.

6. Bank of ideas

Having studied the theoretical material, the history of the emergence and development of the issue, it was decided to make a product using the woodworking technique, with which it would be possible to make a stool from wood.

During the information gathering process, a number of options were considered:

1 Make a bench

2 Classic stool

3 Small bench

Having considered the three presented options, having studied their features, the need for materials and other components, it was decided: to manufacture the “Stool” product, taking option number two as a basis.

7. Draft study of the basic version

To decorate the stool and improve the aesthetic appearance, we decided to process the legs of the stool on lathe. The prolegs are also machined on a lathe. They decided to make the stool cover from a laminated chipboard, pasting the edge with a textured tape.

8. Product requirements

9. Design specification

10. Tools and equipment

In the manufacture of a stool above the specified design, it is necessary to use manual woodworking tools and equipment:

1. Carpentry workbench

2. Hacksaw

3. Planer

4. Drilling machine with drills

5. Lathe

11. Materials

In the manufacture of this product, it is best to use hardwood.

Hardwoods include: birch, beech, oak, elm, mountain ash, maple, walnut, apple, pear, ash, white acacia. From the above list of wood species for the manufacture of the product, we could use: birch, oak, pear and acacia. We do not use pear and acacia because there were no blanks available required sizes. And the preference for oak over birch was given because of the more beautiful texture and color of the wood.

Rationale for choiceproducts.

This year, for the design project, I decided to make a stool. I have not yet made a product of this kind, and therefore the manufacturing process itself is interesting. He made wall lamps, he made shovels, but he never once made some kind of stool-stool.

At first I had an idea to make a bench: on the street or, for example, in a bathhouse. But I thought about it and reasoned like this: we have a couple of small chairs to sit on the street, and if there are a lot of people, then one bench will not save. Benches are needed in the bathhouse, but this was taken care of as soon as it was built. Therefore, another one there will be useless, except to take up space.

Then I had many more ideas about the future product. For example, I was going to make both a table and a chair, etc. I especially got the idea to make a chair because of the shortage of those at home. The idea was not bad, but I rejected it. First, it is unlikely that I could get desired material; Secondly, due to the complexity technological process: it is necessary, nevertheless, that the back is at an angle so that it does not dig into the back so that it would be impossible to sit, there are other small nuances in the manufacture of the chair; thirdly, I would like a soft, comfortable chair, but I still would not insulate it, even if I did. And who needs a small, hard, and besides, digging into the back, chair? Absolutely no one. So I came to the conclusion that I will do stool.

As for me, this is the most optimal option of the above: there is probably enough material, and nothing sticks in the back, and there is absolutely no need to make it soft. It is, of course, much more pleasant to sit on a normal chair than on a stool. But you can’t pull a chair out into the street. And a stool - anywhere, even on the street, even at home, even in the bath.

So, it's decided. I'm making a stool. But here's another snag, and not even one. First - how to do it? Second - what to do? And finally, the last - how do I want to make a stool? It can be classic, or patterned-painted, it can be “about three legs” or in the style of “de la raskoryaka”. In general, the options are heaps. Just do what you think. But I didn't think that was too long. I wanted, of course, to do something prettier: instead of corners, smooth transitions, and instead of ordinary legs, something more elegant.

Under the number 1, I have shown a variant of the stool cover and its legs. Smooth transitions, grace, the lid can be bent a little more, but ... I still rejected this option, although I was inclined towards it. The legs would have to be machined for a long time, the cover would have to be cut out for a long time. This is all a labor intensive process and would take a lot of time.

The second option is also very good, not as laborious as the previous one. And yes, it looks quite nice. But here you need to make either six legs, or connect them like that. Both of those things would definitely work out for me.

Subsequently, they told me: “Shurik, why the hell do you do all sorts of tricks? Too much time? Make a simple stool, there will be time - you will ennoble!” In general, short and clear. So I decided to make a classic version of the stool.

It is this option that is shown under the number 3. I may not do the partition (4), depending on the strength.

I will make a product from wood, pine, birch, linden, oak, ash - whatever I find. More details in the "Analysis of the selected material".

Choice Analysismaterial.

What I will do, I have already decided (stool). The question remained unresolved: “What to do?”. I will deal with this question now.

Manufacturing methods different types there are a lot of stools, which means that each variety should have its own specific material.

Plastic is very good material, it is waterproof, strong enough, light, even plastic. From this material, you can make almost anything your heart desires. The stool is no exception. But I do not have enough of this material, nor the ability to manage with it. Therefore, this material is not suitable for me.

Various kinds of metals: steel, iron, cast iron, etc. These materials are also good, but in their own industries. You can't sit normally on an iron stool. All the more so, you won’t pull such a stool out into the street: on such a stool you can freeze everything in the world, and burn it, and the stool itself will soon rust. After all, they say correctly: "Rust eats iron." Yes, and products of this kind, made of any metal, are unlikely to look presentable, especially since stools are not made of iron and, thank God, such an idea does not occur to anyone.

The stool must be wooden. And I will adhere to this position. My stool will be made purely of wood, although in many cases the top is made of chipboard and then covered with veneer. This idea is not bad, but chipboard swells at high humidity, like fiberboard, and this is a big drawback.

There are many species of trees, and therefore another question arises - which species to choose? Oak. This, of course, is a noble breed, oak has a beautiful texture, good strength. But oak is a rare tree in our area, it is difficult to process it, so this option is no longer available. I also did not take ash for these reasons.

Linden is a very soft breed, the texture of its wood is not particularly beautiful. The water resistance of all trees is poor, but linden and birch. They don't have that quality at all. So the linden disappears. A birch stool will also not be due to the disgusting workability of this breed.

There are many more options, but it will not be enough time or patience to go through all the advantages and disadvantages of each breed. Therefore, we will focus on pine. It is from pine that I will make my product. Pine, in my opinion, is generally the most optimal and best material. Pine products do not warp, pleasing to the eye with a pleasant texture of wood. The water resistance of pine is not the worst, and it is better to process it than others. Pine wood is easily amenable to any kind of processing. This, of course, is a resinous breed, but I don’t see a big drawback in this. Pine has some more disadvantages, but good workability, beautiful texture and its presence in large quantities cover its shortcomings. Moreover, pine is the most common material in our country. And some of the "pros and cons" of other tree species are shown in the table below.

water resistance	strength	resinousness	tendency to crack

I think not to use nails and various screws or self-tapping screws in the product, although I do not deny the possibility of their use. Parts will be fastened in grooves and on glue.

I'm going to finish the stool after. Then sand and apply a second coat of varnish. All this is done so that there are no bubbles.

Manufacturing time.

It took me a long time to make the stool - eight hours and twenty minutes. It took me two hours and twenty minutes to complete the lid. For about ten minutes I sawed the tire boards along the length. Then it took ten minutes to drill holes for the fasteners. It took about five minutes to make each of the fasteners, and there are nine such fasteners. Forty-five minutes - making fixtures. Another half an hour - grinding the parts that make up the cover. Then forty minutes I rounded the corners and spent another five minutes fine sanding.

It also took a lot of time to make the legs of the stool. Four blanks had to be made from a bar. Then they had to be sawn off desired length and planing, because there were a lot of bumps. Then grooves were made in the legs with a groover. These works took one hour, twenty minutes. It took another forty minutes to finish sanding and cleaning. In total, work on the manufacture of legs lasted two hours.

It took twenty-five minutes to make one insert. Those twenty-five minutes included: five minutes sawing to size, another five minutes planing, ten minutes grooving, and another five minutes sanding. It turns out that it took one hour, forty minutes to make and process all the inserts.

Next - the manufacture of partitions. Here I had to plan, cut to length and grind. It took me thirty minutes to make the partition: five minutes sawing, another five minutes sanding, ten minutes planing. It took about ten minutes to cut the fasteners, but this is only for the first partition. The rest I stamped in twenty minutes.

It took only half an hour to assemble the stool. In total, it took eight hours and twenty minutes to make the stool.

Analysis and evaluation.

Having assembled my product to the end, I rated it "five".

The stool turned out not as it was intended, but even better. View - a feast for the eyes. beautiful shape stool, its practicality indicate great effort and a considerable investment of time.

The stool has a rounded lid, so you don't have to worry about sharp corners. It took a lot of time to make the parts needed for the stool, but this does not mean that all parts of the stool are made "without a hitch and without a hitch." Some parts are not very well polished, but this is not due to the fact that "reluctance to grind", but a defect in the material. Some of the grooves and fasteners did not fit during assembly, but it’s impossible to stamp almost at home. This was a flaw during assembly and, I hope, it will not affect either the stability or the strength of the stool assembly in the future.

The product would have looked better if it had been patched, but there just wasn’t enough time for it. But the appearance of the stool is not spoiled by the emerging heads of nails or screws.

Everyone rated my work as “excellent”. Even my father, who reproaches me for carelessness, appreciated my work well, although we made this stool together. The brother said that the product was good, but it would still be possible to take a minute to tinker. In general, the product turned out well.

Advantages and disadvantages.

The product turned out to be good, but it has both advantages and disadvantages.

I consider the advantages of my product:
