how to make model of a clinometer?

 A clinometer (also called a declinometer) is an instrument that measures vertical slope, usually the angle between the ground or the observer and a tall object, such as a tree or building (angle of elevation), but it can be used from the heights to a lower point (angle of depression or decline). Clinometers are frequently used in astronomy, surveying, engineering, and forestry. While you could purchase one of these very useful tools, they are also remarkably easy to make. Here's how to make them and as a bonus there are applications with examples of how they may be applied.
