How to Make a Crankshaft

Lathe workshop in Indonesia to make the crankshaft of zero so far had limited means and constraints that must be mastered problems of mechanical engineering theory in depth not only that but also mathematics and physics, from the shape looks normal, but it turns out the formula attached to the object to form crankshaft, and no objects are created in such a way without a reason of said crankshaft which sometimes forms vary, the problem is not much engineer-engineer of mechanical engineering who want to share knowledge freely Theory about the making of this crankshaft if not in college, for a moment, let us see the video how to make crankshaft with a lathe.
