How to make a ladder to the second floor

The ladder consists of several main parts. This steps, risers, stringer and the handrail or the railing. The bowstring, which is also called the stringer, it is a carrier Board that holds the rest of the design. Its strength depends on the strength of the entire stairs and the safety of the people who will be on it to rise.
