Complete Instructions and Working Drawings for Building a Two-Foot Model Submarine


CHAPTER II
HOW TO MAKE AND WORK A MODEL SUBMARINE

The best way to know how a machine works is to work with it, and the next best thing to working with an actual machine is to work with a model which you have made with your own hands.

In this way you not only will become acquainted with the mechanism which is used to obtain a certain result, but if you are of an inventive turn of mind you are likely to get one or more ideas for improving it which will be of more or less value.

Now, this is just what you should do with the submarine if you really want to know the innermost secrets of how it is made and works—that is, you should build a model of one and experiment with it.

To the end that you may do this, I have given in this chapter the plans and specifications, which mean the working drawings and a full description, of a 2-foot model submarine boat which you can easily make and run yourself.

This model submarine is not only instructive but it is “amoosin’,” as Artemus Ward used to say, for while it starts out awash—that is, with its deck just about level with the top of the water—it will soon take a dive, run a ways submerged, and then bob up on the surface again, just like a real submarine.
