The Oregon Trail was very hard; people would walk for most of the day, and there weren't very many opportunities for fun.t was very tedious and exhausting, not much fun at all. About 1 in 10 people did not even survive the trip----it was that dangerous to follow the trail across the continent.
Turning is the machining operation that produces cylindrical parts. In its basic form, it can be defined as the machining of an external surface: with the cutting tool feeding parallel to the axis of the workpiece and at a distance that will remove the outer surface of the work.
Cold saw(ing) machines are circular saws that are used in many metal cutting operations. The saw blades used are quite large in diameter and operate at low rotational speeds, and linear feeds. There are three common types of blades used in circular saws; solid-tooth, segmental tooth, and the carbide inserted-tooth.
