All these projects shown below are from the new book "Two Shop Masters", you'll get 48 articles in this book. And Yes, you do get the whole book! During the history of the Village Press magazines (Live Steam, The Home Shop Machinist and Projects in Metal), some giants have appeared "out of nowhere" to become contributors to one or all those publications. They are giants in every sense - the quality and quantity of articles contributed for publication being beyond an editor's wildest dreams. This book contains the final legacy of two author/machinists who were indeed giants among all those who have provided material to get into print. The first part of Two Shop Masters is from Frank McLean, whose vast experience as a journeyman machinist, tool designer, and teacher has given the hobbyist 30 years worth of Frank's expertise. His belief was always that machinists should do it as simply and easily as possible. His designs were elegantly simple and functional - easy to understand and easy to make. Generally, his section of the book deals with making your own tools, jigs and fixtures, with a few machine tool accessories thrown in for good measure. The second part of the book features the final work of Philip Duclos - five cleverly designed and diverse engines for you to build. One is an unusual steam engine with several frantically oscillating cylinders, while the other four are unique hit 'n miss engines that will challenge your skill and imagination. Wherever you turn in this book, you'll find shop wisdom and a joie de vivre in the workshop that each man carried with him throughout life. Let me show you some of the projects from the book. Really a most appropriate name, since this little motor does sit on its head. Of course this is not a new idea. Almost a century ago several companies were manufacturing large engines of quite similar appearance. The Topsy-turvy is a small water cooled 4-cycle "hit 'n miss" motor with another feature from the past - the unusual ratio of a 1" bore to a 2" stroke! It performs beautifully at about 800 rpm, the governor controlling its speed. No welding or castings are required for its construction; most of the parts are machined from solid blocks and pieces of metal. Certain items that will speed construction of this engine can be purchased from mail order supply houses. The gears are from Stock Drive Products, 2101 Jericho Turnpike, New Hyde Park, NY, 11040. Stock number for the large brass gear is No. 1B2-N32044. The small gear is No. 1C2-N32022. You'll have to alter the gears somewhat. The spark plug and piston rings are available at Power Model Supply Co., Route 1, Box 177, N.W. Corner, Hwy. 67 and Long Road, DeSoto, MO 63020, or at Cole's Power Models, Inc., Box 788, Ventura, CA, 93001. Construction of this quaintly attractive little engine will prove to be a fun project, and when completed you'll really have something to be proud of! Interested? Then let's get started! Here are more introductions for other helpful and fun projects. History informs us that a four-cycle gasoline engine designed to operate without the use of gears is an old idea. Nearly a hundred years ago, several companies (for a brief period) were building such motors. Information as to how they accomplished this mechanical magic is meager. As you know, in an ordinary four-cycle engine, the camshaft revolves at half the speed of the crankshaft. Usually, this is done with the aid of reduction gears or chains, or even a cogged belt drive. So how did the old-time designers accomplish this half-speed reduction without the use of the above items? Frankly, I don't know, but after a wobbly period of mental gymnastics, I came up with this design for a small 3/4" bore four-cycle gearless hit 'n miss engine. It is made of easily obtainable materials and no castings are required. Performance of this little motor is very gratifying. Its governor can be adjusted to operate the engine in a safe range of about 500 to 850 rpm. It was tested on several occasions, running at 850 rpm in 90° weather for over three hours at a time. There was no evidence of excessive heating, largely due to the abundance of oversize cooling fins on the cylinder and head. This 3/4" bore model "hit 'n miss" engine certainly is not branded with some of the typical features usually present on an average motor. For instance, there is no water jacket to cool the cylinder, nor are there air cooling fins. Gears have been eliminated and the exhaust valve cam is mounted directly onto the crankshaft. There are no piston rings, and the flywheel can be mounted firmly onto the crankshaft without the aid of a keyway broaching tool. Lubrication for the piston and cylinder is provided by adding two-cycle motor oil to the fuel. In other words, Maverick is a simple, inexpensive motor constructed from easily obtainable materials. The engine starts promptly and performs very well; the governor is adjusted to hold the speed down to about 700 rpm. All of this is not to say that Maverick is an improvement in design over a typical engine; it's simply an unusual method of building a motor - a fantasy in metal that has turned out to be mesmerizing to watch when running! Not really. No engine has ever existed that looked exactly like this one. However, the spirit of the Victorian era is very much in evidence not only in the odd mechanical design, but also in the grace and ornamentation of the motor. Now, if you're beginning to groan at the thought of trying to apply that ornamentation with a tiny paint brush - relax! The fancy "V" on the side of the engine body is nothing more than a section cut from an ordinary paper doily sprayed with gold paint, and glued in place! The zigzag design on the surface of the engine base is gold colored metallic "baby" rickrack - a type of decorative braid available at the sewing center in your nearest department store. The four fancy feet holding the engine base? Well, they're just slightly altered drawer knobs. The tall water tank visible in the middle background is made from a hair spray can, and the gas tank from a cat food can. Other items of use, such as timing gears and sleeve bearings, can be obtained from Stock Drive Products, 2101 Jericho Turnpike, New Hyde Park, NY 11040. Their stock number for the sintered sleeve bearing is: 7B4-P036. The large timing gear is No. 1C1-N32056 and the small gear is: 1C2N32028. (You'll have to enlarge the bore in the small gear.) Miniature spark plugs and piston rings are available at Power Model Supply Company, Route 1, Box 177, DeSoto, MO 63020, and also at Coles' Power Models, Inc., Box 788, Ventura, CA 93001. The construction of this little 3/4" bore, water-cooled, four-cycle "hit n' miss" engine involves a number of rather unusual machining operations, thereby creating a fine assortment of interesting challenges. So, if you thrive on challenges, this one will vault you into 7th heaven for quite some time to come! You thought that was it? Here's some more!
