Selection of parts for the manufacture of the carousel

The main parts for the manufacture of the carousel are: metal bar approximately 1.5 meters in length, cylindrical ball bearing, four pipe frame, waterproof plywood as a base.

Since the Foundation of the whole structure are the metal parts, then the employees must be treated very carefully. Because their quality depends on the health and safety of children. If the metal has rust, then these areas need to be sanded and painted.
The main part of the carousel is a metal rod. Wall pipe must be a minimum thickness of three millimeters.

When the place where will be located the future of the carousel is defined, it is necessary to mark the center of the design. At this point, you need to dig a hole with a depth of one meter and a width of 20 centimeters larger than the diameter of the main shaft.

The metal pin must be vertically positioned into the excavated hole and concreted. The concrete hardens in about three days. No need to rush, because only when is well frozen concrete, the design of the carousel will stay still and steady.

Further the metal rod need to wear a cylindrical bearing so that the walls of both parts in contact very tightly with each other. This is to ensure that the mechanism was moving smoothly.

When developing the design of the carousel, you must consider the effort to start the rotation mechanism. Below the carousel is easy to operate, the rotation unit should be as inert. Usually the first time, even with very accurate calculations, a merry go hard, but upon further use and periodic lubrication of the rotation mechanism to spin the carousel will be able even by young children.

When the basis for carousel ready, to the bearing you want to weld four pipes (in the form of crosspieces). Tubes bonded to each other with corners or pipe-wrap. Firmly bonded pipe will ensure the rigidity of the carousel. As grounds for the received frame suitable waterproof plywood.

At the final stage, it only remains to weld the corners or pipe that will be attached to the seat. As a rule, the seats are made of wood, these are attached to the back and edges. In addition, for the safety of children while riding on the carousel, the seats need to attach protecting from drops chain.

Carousel with his hands ready, it remains only to paint it in bright juicy colors.

Advice 2: How to concrete pad

When building a house comes to a close, it's time to think about the landscaping of the site. You will definitely want to equip the recreation area, to pave the path, to prepare a convenient place to Park the car etc. All this involves concreting platforms of various shapes. You can, of course, their asphalt, but asphalt is laid independently, you are unlikely to succeed, and from an aesthetic point of view, concrete is preferable.
How to concrete pad
First, using the pegs and string, mark the location and shape of the site. Remove the fertile soil layer and time is stored. In the future you will find it to good use – use for greenhouses, raised beds etc. the Depth of the selected layer should be about 25cm (if you do not plan to place it on the KAMAZ).

Determine whether to pass under the site of any communication. If so, lay them "boxes" from pipes or ducts. The soil smooth and tamp lightly.
Now proceed to the sand-gravel cushion is the Foundation of the future of the platform or track. Its thickness depends on the expected load, the higher the load, the thicker layer of sand, gravel and concrete should be.

First add a layer of sand with thickness of 10cm. Moisten it and tamp. Then a layer of gravel of the same thickness. It is also water and carefully seal.
Make the formwork in the shape of a rectangle with sides of 1m and 1.5 m. For its production take edged Board with thickness 20-25mm, a width of 7-8cm (you can use a b/u of the Board).

Install the formwork in the gravel layer so that the top edge of the Board performed above ground level at 2-3cm. the Correctness of installation check level. Lay reinforcing mesh inside.
Prepare the concrete mixture of cement, sand and water in the ratio 1:3 and fill it inside the formwork. Solution put a bit more upper-edge casing boards. Tamper (you can get thick 50 mm Board length 1.2 m) level the layer of concrete on the upper edge of the Board. If left empty, add the solution and re-leveled. Give a little to harden and fill with a layer of damp sawdust or rags.

Likewise, fill the next rectangle, until then, pack the entire area will not be flooded with an even layer of concrete. Boards left inside the area, will perform the function of the compensator with temperature extensions and will not allow the concrete to break at the transition temperature from positive to negative and Vice versa.
Within 3 days moisten the sawdust to the surface of the concrete is not cracked during the drying. When the concrete gets stronger, on the outside of the pad Board remove the formwork and install the curb.
Useful advice
Well at the base of the site (the sandy layer) to lay the film that let moisture in only one direction.
