Stepping from the other long side of 200-250 mm, on the short sides make one notch depth 30 mm, and then folded along the long edges otvorotnuyu tape under an angle of 60 ° to the plane of the picture. Under the dual recumbent folds corners edges cut at 45 °. Depending on the annual rainfall board chute folded to a height of 120-150 mm.
In the next step on the short side of the picture under the recumbent folds folded edge: The painting zhelobov, the right of the water receiving funnel, Left folds do down, and the right - up. Wall spout is attached directly to the edge of the roof, as it is used in the absence of overhang.

Methods for processing tubes
Options give color. When the scale and rust will be removed, iron carefully washed under running water, and then dipped into a prepared one of the following recipes for blackening solution.
- water - 200 parts; sodium hyposulfite - 16 parts; ammonium chloride - 12 parts; orthophosphoric acid - 1,4 parts; Nitric acid - 0,6 parts.
- Gradually, the solution was brought to a temperature of about 70 ° C and placed it approximately iron 20 min. As a result, it is covered with matt black foil.
- Exert its effect solution may be at a temperature 20 WITH. The product in this case it is necessary to keep it at least one hour. As a result, the matte black film appears on it, but less strong, than at 70 "WITH.
- water - 200 parts; caustic soda - 130 parts; sodium nitrate - 35 parts. The temperature adjusted to 135 ° C solution in 1,5 hour lowered iron, which is covered with shiny black film as a result of this procedure,. water - 200 parts; caustic soda - 300 parts; sodium nitrate - 6 parts.
