If you at least spent a joiner's instrument in your hands, then for you the manufacture of the stairs is simple. Moreover, individual finished parts are sold in a construction supermarket.

The standard inner staircase consists of: steps and concerns, railings and subsellites, cososov, support pillars, balusters, fasteners, additional elements - fittings.
2
Main detail - step. We select standard sizes. The width is usually 30 cm, the length is 80-120 cm, the thickness of the board is 3-4 cm. If it is planned to manufacture a staircase without concerns, then either pick up a level of less than 100 cm wide with a thickness of 2.5 cm or more or 100 cm with thickness More than 3 cm. In the first case, the steps will force additional straps, and in order to distribute the load evenly in the second, closer to the center, we will place the bearing elements - the remains or boosters.

In case the design includes risers, then we will keep in mind that this carrier element. Therefore, the thickness in the range is 1.8-2 cm, the width is from 18 to 20 cm, and the length is 80-120 cm.

Course size is chosen in accordance with the design of the stairs. Actually, Kosur is a triangle hypothen, where one cathe is the height of the lift, and the other is the projection of the lands on the floor plane. We will be erected in a square, remove the root from their sum - and now it turned out the length of the Kourow. A valuant from the supermarket will have a length of 300 to 485 cm with a width of 280-350 mm and the thickness of 3.8-4 cm. If such dimensions do not satisfy, then we do it yourself: in a long board, we will perform feeding for steps, after calculating their size and sizes and number.

There are also standard reference pillars with a height of 1 to 1.3 m with a cross section 7x7 cm or 12x12. The dimensions of the handrails, balasine and columns are interdependent, so you need to buy them in the kit, or produce.
6
If we want the staircase to be safe, buying or manufacturing the balusters themselves. The standard is the height of 0.8-0.9 m, and the thickness is 3-8 cm. It should be rigidly, so they are maintained from below and on top with a special fastening. Balyasits are pulled out on the lathe, milling or decorated with carvings.
7
The choice of balusters and a support pillar, determine the form of the handrail. The length of the finished element is 250-350 cm. If a balasine is wider than Kosur, then to mount it below, you need a companion. We install in such a sequence: the companion is a baluster - handrail.
As you can see, the case is simple, if, of course, you do not want to build something extraordinary in the style of baroque or classical with a lot of complex elements, but even in this idea there is nothing at all. The main thing is a great desire.
