Before you start preparing details for the future staircase, it is worth accurately determined by its dimensions. Since we were going to engage in the stairs to the second floor, you can immediately determine exactly to its height, which will be similar to the height of the first floor, to which the thickness of the ceiling is added. As a rule, this distance is 270 centimeters.
Now it is worth determining the required number of steps accurately. As you know, the minimum stage height is at a mark of 18-20 centimeters. If you take a height, that is, 270 centimeters, and divide it by 18, that is, the height of the step, you can find out that the stairs will require 15 steps.
Now it is necessary to clearly determine the dimensions of the projection on the floor in order to understand the intricacies of the location of the structure indoors. The perfect width of the downshole lies within 25-30 centimeters, multiplying this distance by the number of steps, you can get a result of 375 centimeters. Pythagoras theorem will help to find the exact length of the stairs, which will be at the mark of 462 centimeters.
After all these calculations, you can manufacture the components. A wooden beam, the cross-section of which is 140 by 60, will help in the manufacture of a pair of Kosour, boards of 3-4 centimeters will become a material for the production of steps, and boards of 25-30 millimeters will make it possible to make approaches. The length of the step should be correlated with the dimensions of the room, but it must be borne in mind that with a march width less than a meter you can encounter a number of inconvenience. When buying wood for the stairs, it is necessary to pay maximum attention to its quality. The tree should be free from gray areas, do not have cracks and visual deformations.
Determining the moisture of wood without special equipment is an impossible task, but if the excess of humidity is critical, then the board will be very difficult. A strict tree must have a perfectly smooth surface, free from roughness and knots. Ideally, the wood, which is designed to make scouring, should not have knots at all. Small knots are allowed on the risers and steps (the diameter of which is less than a centimeter), but you need to remember that if their number is more than one per hundred centimeters, the quality of wood is doubtful.
Note that in the absence of boards of the required width, they may well be collected from two narrow ones, which are connected by glue and furniture dash. Similarly, the designed step is quite capable of replacing a solid option, the main drawback is the fact that sometimes it is impossible to fit the board with perfect accuracy, and therefore it may be necessary to finalize using a rubbish.
Before the staircase on the second floor with your own hands is installed, you need to assemble it in a whole structure, try on each part and fit them to each other if necessary. When the fitting of all parts is completed, they need to be cleaned with sandpaper, paying maximum attention to the grinding of the ends. All compounds are made using stainless steel screws, previously densely lubricating the surface with glue. The use of PVA emulsion is allowed as an adhesive solution.
All the details of the stairs should be carefully processed with a stain and several layers of transparent varnish. Instead of a stain, the use of hot olifa is allowed, the processing of which is conducted twice. Processing should be done before the assembly process so that the screws of the screws are not stained. To protect certain places from varnish and olifa, you can simply glue them with a painting tape.
A staircase that is based on this technology will differ in bulk, but very simple and involves the use of an absolute minimum of tools. Of course, if you want to make a more elegant version of the staircase, you will have to use a more complex technique, which involves the use of not overhead, but mortise steps.
