How to Build a Three Horsepower Launch Engine by E.W. Roberts s/c

cover photo

This is a reprint of a 1901 text written by a well known engine designer with the intention of allowing an amateur to build patterns, machine the castings, assemble the engine, test the engine, and install it in a boat. The book has complete instructions and drawings for every part of the engine, including the igniter and the carburettor.

This engine has a five inch bore and six inch stroke. At 350 rpm it should generate three or four horsepower. This is a brief book, but it's loaded with details and dimensioned plans, but you must know at least a little something about building engines.

From the preface:

" ... the author has tried to point out the best way of making each part, more as a guide to the mechanic, and in order to help him work the parts in such a way as to get the best results, than to lay out a routine that he must follow ...

In regard to the patterns, and especially the cored work, the author advises the assistance at least of a good pattern-maker ...

The engine is so designed that it may be built with small tools, and for this reason the cylinder and the base are cast separately."
