Excerpt from Machine Shop Catechism: Consisting of Over 1000 Carefully Selected Questions and Answers The catechetical form of presenting information appeals strongly to the practical man who prefers a simple answer to a plain practical question rather than an exposition of the principles involved. This form has been employed in the columns of the American Machinist from time to time and a continuous flow of more or less elementary questions arising in the machine shop has led to this compilation. The answers are in accordance with com mon practice and are as complete as consistent with the form of presentation and the space restrictions imposed by the broad fields of work covered.
