THE BOY MECHANIC VOLUME I
Transcriber's Notes
This text accurately reproduces the original book except for adherence to Project Gutenburg guidelines. Each project title is followed by its original page number to allow use of the alphabetical contents (index) at the end of the book. The book used very complex typesetting to conserve space. This transcription uses simple one-column linear layout.
The text only version is of limited use because of the widespread occurrence of diagrams and illustrations. Use the pdf version for the complete text.
Many projects are of contemporary interest—magic, kites and boomerangs for example. Try a "Querl" for starters.
There are many projects of purely historical interest, such as chemical photography, phonographs, and devices for coal furnaces.
Another class of projects illustrate the caviler attitude toward environment and health in 1913. These projects involve items such as gunpowder, acetylene, hydrogen, lead, mercury, sulfuric acid, nitric acid, cadmium, potassium sulfate, potassium cyanide, potassium ferrocyanide, copper sulfate, and hydrochloric acid. Several involve the construction of hazardous electrical devices. Please view these as snapshots of culture and attitude, not as suggestions for contemporary activity.
Be careful and have fun or simply read and enjoy a trip into yesterday.

THE BOY MECHANIC VOLUME I 700 THINGS FOR BOYS TO DO HOW TO CONSTRUCT WIRELESS OUTFITS, BOATS, CAMP EQUIPMENT, AERIAL GLIDERS, KITES, SELF-PROPELLED VEHICLES ENGINES, MOTORS, ELECTRICAL APPARATUS, CAMERAS AND HUNDREDS OF OTHER THINGS WHICH DELIGHT EVERY BOY WITH 800 ILLUSTRATIONS COPYRIGHTED, 1913, BY H. H. WINDSOR CHICAGO POPULAR MECHANICS CO. PUBLISHERS** A Model Steam Engine [1]
The accompanying sketch illustrates a two-cylinder single-acting, poppet valve steam engine of home construction.
The entire engine, excepting the flywheel, shaft, valve cams, pistons and bracing rods connecting the upper and lower plates of the frame proper, is of brass, the other parts named being of cast iron and bar steel.
The cylinders, G, are of seamless brass tubing, 1-1/2 in. outside diameter; the pistons, H, are ordinary 1-1/2 in. pipe caps turned to a plug fit, and ground into the cylinders with oil and emery. This operation also finishes the inside of the cylinders.
The upright rods binding the top and bottom plates are of steel rod about 1/8-in. in diameter, threaded into the top plate and passing through holes in the bottom plate with hexagonal brass nuts beneath.
The valves, C, and their seats, B, bored with a countersink bit, are plainly shown. The valves were made by threading a copper washer, 3/8 in. in diameter, and screwing it on the end of the valve rod, then wiping on roughly a tapered mass of solder and grinding it into the seats B with emery and oil.
The valve rods operate in guides, D, made of 1/4-in. brass tubing, which passes through the top plate and into the heavy brass bar containing the valve seats and steam passages at the top, into which they are plug-fitted and soldered....
