Salient Features

The purpose of this article is to set forth the most modern design of tools generally used, such as jigs, fixtures, punches and dies, etc., and why they are used, together with the degree of accuracy that may be expected in the manufactured article when made by these tools in the hands of an unskilled operator. There is such a vast difference in the methods and the degrees of accuracy required in the manufacture of harvesting machinery and of watches, that it precludes all possibility of establishing a standard design of tools. However, by closely studying the following designs, and the reasons for employing certain tools for certain operations, the student will be able to decide which tools are best adapted for the various operations on the contemplated article of manufacture.
