How to make a toy tractor with a motor. Homemade children's educational toys. Two katonchik gun
It is hard to present agriculture without the use of special equipment. But most private farmers cannot afford the purchase of a mini tractor. In small land, you can do with manual instruments, but on the square more than 1 hectare it will not be enough. The homemade tractor is not inferior in the effectiveness of most factory models.
Basic varieties of homemade tractors
Due to the high flow of fuel, mass and dimensions, the use of large and powerful tractors in a small area is inconvenient and irrational. For their manufacture, accurate calculations are required, which are difficult without engineering skills at home.
The mini-tractor is considered a multifunctional technique and is able to handle up to 10 hectares. This is enough for private farming. It should be approached not only to care for the garden, but also for cleaning the snow, transportation of goods and debris. When designing its design, these features should be taken into account.
There are 2 approaches to creating your own tractor:
- Re-equipment of finished agricultural machinery. In the overwhelming majority as the basis protrudes the motoblock to which the frame is joined with an additional pair of wheels and the driver's place. This method allows you to quickly and with minimal efforts to build a simple and function tractor.
- Full manufacture. It is used in the absence of a base or with specific appliances requirements. In this case, the chassis is designed and manufactured independently, and components are selected on the basis of financial capabilities and structural features.
Some enthusiasts build steam tractors. A separate boiler allows you to use almost any kind of fuel fuel. This type of energy conversion was distributed in the 1900s. Due to the low efficiency, the bulky design and the small stock of the steam engines cannot compete with the engine. The use of obsolete technologies in agriculture is a costly event and is used for entertainment.
Features of tractor manufacturing
The homemade technique has the most simplified scheme, and during its manufacture, nodes and aggregates from other equipment are used. The goal is to get cheap and reliable design. For assembly, the basic instrument handling skills will be required and minimal technical knowledge.
When designing its own design, use details with minimal modifications. Parts should be easily accessible and inexpensive. A large number of self-made elements in the design will lead to an increase in the cost and duration of repair.
Performing accurate calculation of strength and loads is almost impossible at home, therefore the frame and the remaining carrier structures are manufactured with a large margin of strength.
If there are drawings and the necessary equipment, the tractor itself can be made in 3 months.
Preparation of drawings
Before purchasing and preparing nodes, the project of the future tractor must be compiled. As a basis, you can take drawings of finished models. Spare parts that you have, may differ from the claimed, and it will be easy to change the finished design scheme. There are ready-made solutions for any modifications.
If it is not possible to use a finished project, then it is necessary to prepare draft sketches yourself. In the process of assembly, the layout of the elements may change, but you must understand how individual nodes will be located.
This toy came to us from the Soviet Union. When apparently for children, it was not easy to buy something special somewhere, but I still wanted entertainment. This thing is really impregnated with some particular spirit of the time when a lot of what they did with their own hands and actually did not worry about this, but even felt some superiority before those who could not do this. Although noble, we think it was much less than in our age, when a Chinese bauble can be bought for a couple of kopecks. However, we will not look for the truth when it was better and what the features of each of the times, and tell you about the toy - the tractor from the coil of threads on the rubber coil.
Toys on a tberling engine for children
This article describes another of the toys on the rubber engine, a universal energy source. The twisted elastic band is able to promote and thereby provide a certain torque. In the future, this torque from the gum can be used to rotate the propeller as in the airplane, which we have already been told or for the rotations of the wheel. In our case, it will be a wheel, in the form of a coil. Let's now about it in more detail.
Tractor from the coil on the rubber coil, toy for children
For toys, we need the following. Coil with protruding edges. It may be a coil from threads, or from something else. It will be necessary to ring elaborate, match, rod, rod or candle, and maybe just plastic washer.
How to apply all this to get a self-propelled remedy?
Initially, we make notches on the coil. They will help the edges of the coil to cling to the surface on which our tractor will go.
Especially if it is embossed and soft. Next, we break the match so that it is not larger than the diameter of the coil's end. Also we produce from a wash or candle washer. You can use a plastic washer. In fact, such a washer will be a sliding bearing. If you are lining with lithol, at least a thin layer, it will be quite good. In order for the match on the end it is not turned, we make a deepening. You can then glue the match, with the help of glue.
Now we collect our tractor. Since actually production work has ended, assembly began. To make it better to imagine how to collect everything, look at the picture.
The gum is done through the hole in the coil and puts on the match.
On the other hand, a hole washers and a rod. All, toy is ready.
Now it is enough to spin the rod several times, in any direction and put the design to the surface. The rod will begin to scroll until it strives to the surface. Further scroll will begin the coil. Since still something is spinning should ... Release the energy of the twisted gum. The rotation of the coil will ensure the movement of the entire design on the surface, so it will ride. Here is such a toy tractor with his own hands. Pluses in its manufacture a lot. If you do with children, you can thus develop a motorcy from them, study the world around us, teach them to work with your own hands. Of course, there will be a plus that they will have a new toy that can be played.
Homemade children's toys Always interesting. Each toy made for the child possesses the love and energy that is embedded in it during the construction. No wonder children are sometimes very careful to non-zeep toys.
Currently, there are a lot of different color and beautiful children's toys in stores, so homemade toys do very rarely. But hidden meaning in homemade technical toy Just and is the process of creating a toy, thinking, building it with your own hands using the tool. Moreover, such a process takes place jointly with someone from parents or senior brothers and sisters, especially when children are small and cannot work independently with the instrument, this is simultaneously playing the learning process.
Purchased educational toys (such as the designer "LEGO") is very good, they allow you to collect many designs, but the weak link is that everything is going from ready-made bricks - just fasten these bricks among themselves and we get a planned design.
In such a game, the initial elements of creativity disappear - the choice of materials, processing their hands using all kinds of tools until the necessary form is obtained, fastening the necessary methods, achieving the necessary function.
Therefore, a homemade toy is a truly educational toy.
In childhood, we were forced to build toys and accessories to the game for games. Many of them are undeservedly forgotten. I will remember to remember some homemade toys for boys, let them bring joy to children and their parents.
Wooden coil tractor
Such a tractor is interesting for boys 3 - 7 years old. It is made from the coil from under the thread or, as we called it - Katumchik.
On the wooden cheeks of the Katon, the deepening is neatly cut - this is a prototype of the tread on wheels or hooks on the caterpillars. 
Such hooks allow tractor from the coil Clearly crawl on sofas and pillows. The basis of the engine is rubber. Her length should be a little longer coil. The best rubber is airmodal, good rubber can be carefully spent from ordinary clothing gum. Such rubber gives a large stock of the stroke.
On the one hand, a small carnation or two is clogged into Caton. An elastic band can be hooed in one end for the carnations, and you can put a piece of matches for the carnations - then the rubberotor is fixed exactly in the center, which gives another extra stroke. 
So that the rubber is spinning at a low speed, between the supporting stick (or match) and the coil's cheek is placed from the economic soap. 
Its diameter should be slightly smaller than the diameter of the wheel (so as not to interfere with the movement), and the thickness is near the centimeter. The center is the hole with a diameter of 4-5 mm, for a support match - a small groove. You can make a clutch from a bath soap - it is a little softer, it is possible from a candle or a ski paraffin. The softer the material of the flutter, the more slower slows down and, therefore, the tractor is going.
The assembly and launch of the tractor is shown on the video.
This tractor does not spoil anything and does not publish any sounds. Little growls only the child himself when he plays.
Toy "Buratino with a ring"
This toy is cut out of the 4-millimeter plywood publs. First, a drawing is applied to the phaneer through copying, then cut down. The edges are treated with a skin, then everything is painted and covered with varnish. At the end of the nose, the little hole is drilled and a harsh thread is tied with a length of 50-70 cm. By the end of the thread, the ring is tied with a diameter of 3-7 cm.
The ring can also be chopped out of plywood or find a suitable ready.
Holding the profile of Pinocchio in hand, it is necessary to jerk threads to throw up the ring and put it on the nose. The smaller the diameter of the ring, the hard to do it.
There are several people at once, trying to score as much of the resulting throws for a certain number of attempts.
Acting model of sailboat
Being in the summer on vacation near the water, you can make a lot of pleasure to make making and launching small sailing boats.
For the manufacture of such it is enough to have with you only a sharp knife. A suitable piece of dry wood is taken or, even better - a pine crust that sometimes falls on the river or lake. A knife is painted a housing of a boat - a flat-bottomed boat with a sharp nose and rounded feed.
The case is tested on the absence of a roll.
Then the case is made in the case - one vertical in the middle of the feed for mounting the steering wheel and another incision tip knife right in the middle of the housing along the fibers for fastening the mast.
The mast is made from a round bar, light and durable. One end of the rod is sharpened with a shovel and clogs the knife with a knife in an incision in the middle of the housing. The steering wheel is littered from a flat pinch of a width of about about the thickness of the boat housing and a length of about one third of the housing length. The steering wheel is also clogged with a knife in an incision on the stern of the case, and the steering wheel should be all shipped into the water.
The sail is cut from Berrés using a knife. The top and at the bottom of the sail are made round holes, with the help of which the sail of the battlefield neatly satisfy on the mast.
You can equip one mast several sails.
Sails can be made of plastic bottles, and the body of the foam. You can build frigate, equipping the ship by three masts and a lot of sails. The main thing is that it does not turn to the severity of the snap and tolerate well.
After several buildings, experience and ships comes well hold the course and gain a good speed.
If there are several sailboats, you can arrange a small regatta for speed and accuracy. It is very convenient when there is a shallow closed with a reservoir, where it is possible without fear and without loss of ships to work out launches.
Paper planes
The child 5 - 7 years is usually easily controlled with scissors, and these schematic flying models of aircraft are quite capable of building themselves.
The best thing paper planes It turns out from postcards - they have good dense paper and suitable dimensions. Airplanes are well holding the shape and fly well inside the room. 
Cut the model classes can be all sorts of shapes and structures, you can experience a flying wing, make two stabilizers, make wings of various sweatshirts. 
Each form of the model has its own flight characteristics, its flight speed and its resistance in flight. When building a flying model, it should be taken into account, one hundred all lines of the aircraft must be perfectly straight, that is, the paper should not be mint. Paper folds neatly stroke the nail.
The center of gravity of the model should be on the first third of the wing. The angle of the attack of the rear wings should be within 15-20 degrees, it is selected experimentally and then it turns out automatically. A well-planning angry model should be out of a vertical peak with an extended hand and smoothly sit on the floor. The airplane, fastened up from the floor, makes a dead loop and produces a soft landing.
Gymnast on the crossbar
The basis of the toy is "n"--like bed of two wooden specks bonded in the middle of the bar. In the top of the bed, two parallel threads stretched through the holes in the hands of the gymnast figures in the "legs up" position.
The figurine of the gymnast is cut out of a veneer or other thin material. Hands and gymnast legs are hinged with a body with a thin wire.
In the initial state, the gymnast hangs on the threads down, and the threads are 180 degrees to the left and right of it.
If now slightly squeeze the lower ends of the crossbar, then the threads will stretch and the gymnast will make the rack on the hands. If at this moment there are ends of the crossbar at this moment, then the inertia gymnast will turn over to the other side and the threads will be twisted again, only to the other side.
Changing strength and sharpness of pressing you can get very interesting pyruets of the gymnast.
Suceeded with a rubber system
Creature suceeded with a rubber systemEven very simple, already the process of creating equipment. Here there are already trees, screws and brackets, there is something to think about and make.The simplest ship-seeker is a wooden boat with a rhubber.
The body of the boat is painted from a wooden plate, cutting out a suitable bar or a piece of polyfoam. Next we build a rubber engine. To operate the screw from a tin, we make a bracket with a tube for the shaft (we rock a nail) and flexing the ears for fastening. The bracket can be attached by cloves or small self-drawing.
The screw cut out from the tinned tin, in the middle of the axis from the stationery clips and bend the blades of the screw.
Then we put on the axis of the bead as a bearing, insert the axis into the bracket and bend the hook.
Ahead of the case smooth the wire hook for gum. The rubberotor is made from aircraft or fishing gum. The number of gum is selected by an experimental way. In the free position, the rubberotor should be saved at about half the length of rubber. Rubber ends can be covered with threads by inserting rope loops.
Feather steering boat should be located right in the center of the screw. The axis on which the feather of the steering is kept, should provide a steering wheel of at least 45 degrees, then the model can be allowed on an arc.
For the convenience of the rhubber plant, instead of a hook in the nose body, you can put a nasal bracket with a fixed handle.
You can build a submarine on the rhubbinder, which can be immersed on the depth of meter and even more.
So that the submarine on the go was immersed in water, she needs the depths and a very small positive buoyancy. Two pairs of depth steering is also made of tin. To regulate buoyancy, we use flat lead weights. We achieve that only the cutting of the boat is visible on the water. The differential must be zero, that is, the boat should not peck down nor nor feed.
Before adjusting the buoyancy, the submarine must be painted, otherwise after several launches of wood wet and the submarine will forever go under the water.
The longer the housing of the shipyard with the rubber coaster, the greater the reserve of the stroke. Also on the reserve of the course affects the quality of the running screw.
Boomerang-frame
Being in nature, you can make a very simple boomerang in two minutes - a frame of five flat wooden specks with a length of 20-25 centimeters. For this rail, they are wooped according to the drawing. The design is kept due to the bend of the rail.
The frame take in the hand for the lower part of the central rail and thrown in a vertical position and a little up, and it, as a real boomerang, falls on the side and, making a circle, returns back.
If it knocks on a solid subject, then scattered on the part. It is cool, you can collect again.
Simple car with electric motor
The easiest car with an electric motor has a wooden frame from a plank or plywood, four wheels in pairs on two axes, no steering, transmission is straight - from a motor shaft, on which a rubber tube is dressed - right on the car rubber wheel.
The meaning of such a car is to feel the excitement of construction, see the dynamics and power of the electric motor, study the foundations of electrical engineering. The wheels of the model are taken ready from a suitable toy, the axes are made from cycling spokes. The mounting brackets of the axes are cut out of fasten and fasten with self-draws or screws.
The electric motor is attached to the bracket to the frame.
A luck will be easier to fasten the electric motor on a non-rigid elastic loop bracket, then the clutch with the wheel will be more reliable.
The car is powered by a double wire (from any low-voltage adapter). Batteries and stop-back switch are collected in any plastic box of suitable sizes.
You can play, just running over the car, but you can make a circular track and secure the wire in the center of the circle.
Developing the interest of the child, you can design a stroke control with it, steering, and then it myself will design steeply managed automodels and disassemble your favorite car.
Two katonchik gun
Children's gun is going out of 2 wooden katonchiki.One of the ends of the first Cathon is grinning straight, leaving the fly, the lower edge is cut to the level of the middle, and the neckline is made in the upper part. It will be a gun barrel with a sewer.
The second Caton is used unchanged. It will be the wheels of the gun.
You still need a piece of rail 2cm width and a thickness of 4-6 mm, the length is about half the length of the Caton. It will be a kind of emphasis and hook for a shrom.
The most complex part in the cannon is a shrom. The pushing part should be round and without friction to enter the trunk. Length is a little shorter of the trunk of the gun. Rear: width - in the width of the stop, height is 1-2 mm, the height is 2-3mm, but not to clinic when shooting. All the faces in contact with the barrel shield (except the top to avoid injuries), should be steep, so as not to jin. The length of the rear -2.5-3cm, on the back side a small cutout for gum. Material - Birch. Pine is also suitable, but more often falls apart when shooting.
Gathering gun on threads for sewing.
First, threads tightly tied a rubber loop by the ends on both sides. Then it is attributed to the stop and immediately tie the bottom Caton - wheels, well-tightening the threads crosswise.
We insert the ammunition and put on the back of the rubber. The gun is ready.
Shoot the pea or how to find. We bring a shore, engage for the edge of the stop, charge the pea, put in the shooting position.
Now, if you press a finger on the top of the shield, the gun will shoot.
Bow and arrows
Onions and arrows are acceptable to playing outside the city, because the arrow released from the onion is flies relatively far away. This is not a sports bow, but a distant one for the game and workout with its techniques and shooting technique.
Onions are made of a smooth piece of willow stem with peel or versa (juniper), which is even better. A piece of barrel with a length of 50-100cm is selected the necessary stiffness to have enough strength to pull onions.
The string is made from a strong kapron thread. The string is attached at the ends of the onion into the cut-off grooves, and it is tied in a non-tentuent state.
In order to tighten the the tent, they rest on one onion to the ground, the other hand bends onion and wound into the groove to the tension to the required tension. Therefore, the groove for winding the teta must be made with a dealer with the channel for pulling.
The arrow is painted with a knife from a smooth piece of timber of specking, it is cleaving that the treatment with a knife occurs exactly on fibers. Otherwise, the arrow will not be made.
In front of the boom, a thick wooden tip is left in the form of a thickening, which is spinning so that the arrow could not bear much harm. On the back side of the arrows, a shallow groove for the taisle is cut. The technique of shooting is the usual, the only one, with such a design, the grip of the arrow's shank is not sporty - for the guide, and the game - two fingers for the arrow shank.
Simple toy self-propelled tank with electric motor
About the same technology as for a simple car, you can build toy self-propelled tank. Such a tank is to play even more interesting, because it can overcome significant obstacles.
The speed is small, so it is convenient to work with a wired remote control. Simple tank design does not provide its turns, only move forward-back.
The design of the transmission tank is much more complicated than the car. Here is applied a multistage gear from gear from toy machines. You can choose a suitable ready gear, and you can collect a simple gearbox yourself.
First you need to pick up gears.
The main running gear of the vague is shaped or soldered on the axis. For fastening the gear, cloves of the desired diameter are selected and dry up to the desired length.
A suitable rectangular bar of strong tree breeds is taken. It is approaching the position of the adjacent gear and, accordingly, the position of the bar.
Then we work separately with Bru. In the marked place we bring the sample gear, then try on and tip the following.
We press the bar with the gear to the running gear and secure it to the tank frame by self-draws.
When the small gear is signed on the motor shaft, the second end of the shaft must be overtaken in the odor, so as not to break the engine. Cress the gear of the electric motor to the gearbox and the crepim clamp.
Leading shafts and sloths tank are selected from unnecessary automobiles.
With rinks, the problem is more. They can be made of gaming plastic checkers.
Drills in the centers of the holes of the hole with a diameter of 2.5-3mm, we connect two checkers with planes inside, we draw a suitable piece of PVC tubules into the holes of the PVC tubule and smooth the axis. If dimensions are met, everything keeps perfectly.
Caterpillars glue from the rubber band from the bicycle chamber, the soils can be glued with rubber, and you can sew wood from matches. Caterpillars should be jagged on rollers tank. When scrolling the caterpillars, the leading roller can be rubbed in the rosin.
Such caterpillars sometimes fall during operation, but it can be corrected by restrictive colors on the sloths. In general, full space for upgrades.
Tank superstructings can be glued from any suitable material.
If on each caterpillar tank put a separate gearbox with an electric motor, it turns out a full-featured model. The axes of rinks and sludges must be replaced by separate semi-axles for each side.
The control unit will also have to be modified to manage the two engines.
Today we will return to those times when the lack of toys in stores forced to work fantasy of children by 300%!
Your attention is a homemade toy - a tractor from the coil of threads.
For the manufacture of a classic tractor, a coil of threads was required, a candle segment (used as a sliding bearing), a gum from the biguch or a segment of the cycling chamber (in today's realities can be replaced by 5-6 pieces of rubber bands from the money folded in half) and the paste from the ballpoint pen.
In the photo above you can see the self-made tractor made with your own hands in the classic design. It is such self-propelled toys that we have fun in the 90s. Then it was much cooler than a bouquet of Teddy bears in today's days. We have satisfied the races of homemade toy tractors in the rough terrain of the sandbox (it was for this that they needed large soils, they were usually cut with kitchen knives). Competed on the speed of overcoming the route - therefore, the gum must be "powerful" enough. In the course of the movement, homemade toy tractors overcame different obstacles - climbs and died in the sand of Rips, stony terrain of small pebbles and so on.
Competitions could pass all day long! Elastic bands are bad to keep the twist and easily can be sprinkled during excessive revs. Or begin to "slip on the spot."
If you want to make a toy homemade tractor with your own hands, then look at the video below. There, the teenager is trying to recreate the technology of an ancient toy.
As you can see - it turns out very weak. Firstly - too weak elastic. As we said - in a homemade toy, the tractor from the coil from the threads should be applied not alone, but immediately harness the rubber band - this will increase the specific power of the rubber beam.
Secondly, in the tractor instead of light paste from the handle, a pencil is used. It is much harder and therefore the toy tractor goes with a very slow speed.
Make the same thing, but use the paste from the handle and 6 elastic bands from the money folded in half, your tractor just swears from the place with slipping! If the start is performed on the sand, then you can watch emissions from under the wheels!
Successful game with homemade toy!
Noflick comments:
Instead of a candle, you can use a pair of pucks from fluoroplastic!
He is very slippery, especially with each other and is not spent, unlike the candle!
We offer to make another reduced version of the powerful road construction machine from cutting maple and walnut wood
Smoothing a pile on the carpet, like a ground in the construction of the road, or raving the place to play in the sandbox, this working grader will demonstrate your skill. E.
go swivel risen and lowers, and the sounds of the motor will have to be mastered by the driver itself.
First build the back of the tractor
Note. Drinking the parts and attaching them the final form, polish them with emery paper No. 220 before start assembly.
Pluging a wooden lining on the transverse stop, make cutouts in a cottage and traverse J, to the markup on templates. Remove excess material between extreme propilations for several passes.
Having setting the bottom of the cut from cutting the F / G beam, create a parallel surface for installing clamps to glue from above the clamp and traverse J, k.
By placing the bottom of the trim, drill the hole in the beam F / G through the holes of the J. Clamp
3. Drink the front axle H and drill through the end-to-end hole with a diameter of 9 mm (Fig. 1). Take the previously discharged blank for Kosnok J and throw up along one edge on a section of 50 mm long 10 mm chamfer (Fig. 1C). Screw the jacks of the specified length from the site from the fabric, and put the rest of the workpiece to the side.
4. Nasuhu (not gluing) While the front axle H with a beam F / G, neatly aligning. Drill and slaughter the mounting hole with a diameter of 4 mm through the front axle and the guide hole with a diameter of 2.8 mm in the beam. Get the front axle to the place and additionally secure the screw (Fig. 1). Then glue the Kosinki I to the beam and the front bridge, aligning them in the middle of the width.
Pan in the cutout dump M Rotary slab L with straight corners, aligning the details on the back.
Bonding the front levers about with a rotary block N, grind into the holes of the threaded stiletto.
Slightly tighten the nuts on the vertical levers P and make sure that the parts of the L-0 mechanism are rising and lowered.
5. From the maple wood, cut the billet with a size of 19x22x305 mm for a C clamp and one more, the size of 13x16x305 mm for the traverse of K. Make copies of the templates of the clamp and traverse and attach them with aerosol glue to the appropriate billets. Make cutouts in these items (Photo C), drill holes in places listed on templates, then cut the ribbon saw along the contour and finally seel. Two-millimeter chamfer using a milling table with a milling table, as described in the "Master Council".
6. Using the trim from sawing the F / G beam, stick to the beam of the Clamp J and Traverse K (photo D), aligning them on the marks applied earlier. When the glue is driving, drill through the beam 5 mm (photo E).
7. Align the F-K beam assembly in the middle of the width of the chassis A-E, pressed to the cab cabin.
Stick the beam to the chassis, secure additionally screw and pose the headlights into the hodges of the traverts K.
Dump will climb and rotate
1. Take the workpiece for rotary slabs L, attach it with a double-sided tape to a flat nervous gloss with a length of at least 305 mm, and process a 6 mm thickness on the thickness of 6 mm on the reysmus. Make two copies of the turntable template and attach to the workpiece. Put the details along the contour of the belt saw and ground the edges. Note. At one plate, the rear corners are rounded, in the other they are straight (Fig. 2). Fold both details together, aligning ends and edges,
drill in the specified location 5 mm, then remove the template.
2. Drink away the specified dimensions (Fig. 2a). Make the top edge cutout corresponding to the width of the rotary slab L. Stick to the dump of the rotary slab with straight corners (photo F).
3. Take a nut rail deflected earlier for the rotary block N, disconnect the block of the specified length and drill the 5 mm hole in the center (Fig. 2). Enclose the part to the Rotate plate L with rounded corners.
4. Make two copies of the templates of each lever O, P, Q, attach them with aerosol glue to the maple blank, made earlier, cut the parts along the contour and polish. Drill holes in the specified places and throw the chamfers, then remove the templates.
We start assembly
1. Note. Do not use the sealant-retainer for the cutting connections before the start of the final assembly after applying the finish. Prepare a 100-mm threaded stilette segment and use it for gluing the front levers O, Rotate plate L and the rotary block N (photo G). When the glue is driving, connect the swivel plates with a 22-millimeter cut of the threaded stud with cap nuts (Fig. 2).
2. To fix the upper levers Q to the clamp J, take the threaded pin M5 * 76, washers and cap nuts (Fig. 1). Clean the cut of a threaded stud 67 mm long on the assembly of the I.-O dust into the holes of the upper levers so that it turned out to be under the beam f / g.
Attach the front levers Oh, then connect the vertical levers r with front and upper levers, fixing the assembly with nuts and washers (Fig. 2, photo H). Pro-believe how the assembled node rises and lowers.
Z. In four wheels with a diameter of 32 mm, make 9 mm axial holes (Photo I). Scroll through the wheels with a diameter of 32 and 64 mm to the chassis A and the front bridge H, inserting the axis and washers (Fig. 1). Remove the wheels and all fasteners. Puck the painting tape with the ends of the axes, which will be glued into the holes, and apply the finishing coating on all parts. (We applied three layers of semi-wave polyurethane varnish from an aerosol cylinder with an intermediate grinding abrasive sponge number 320.)
4. When the coating completely dry, apply some glue on the walls of the holes before inserting the axis in them. Re-assemble the details of the rotary mechanism, applying a red sealant-fix-torque for the ends of the threaded studs. Tighten the nuts so that the answer turned and rose without much effort and remained fixed in any position.
