Lil Bertha: Compact Electric Furnace

David J. Gingery

Lindsay Pubns

"There are low-cost centrifugal fans available, but rarely will they do exactly what you want them to. If you're building a small furnace to melt aluminum you can use a surplus fan. If you're going to build a dust collection system for woodworking tools, a welding booth, or a grinding wheel, you'll find that the blowers you need are not available at low cost. Dave will show you how to design a fan with simple math that will provide the volume and pressure you need for the system you're building. With a pocket calculator you can figure out the dimensions of the fan, the size of the motor needed to drive it, and predict performance. You'll be shown how to use pillow blocks, shafting, plywood, sheet metal and other common materials to build a dirt-cheap blower that outperforms any make-do blower you might find on the surplus market. Dave will also show you how to build a simple manometer and pitot tube. You can actually measure performance and fine tune your air system. Dave used this equipment to build and adjust a powerful gas burner for his iron-melting crucible furnace. Learn how to build a dust precipitating cyclone, design sheet metal transition pieces (a very valuable skill), balance a dust collection system, build a static balancing stand, and more. Gingery's brand of simplified do-it-yourself knowledge is not available anywhere else. top rate. Order a copy.

Metal Shop from Scrap

Using castings from your charcoal foundry (see Book 1: The Charcoal Foundry by David Gingery) and simple hand methods (no machine tools needed!) you can build a sturdy and accurate bed for a metal lathe. Then additional castings, common hardware items and improvised equipment will add the headstock, tailstock, carriage and all the remaining parts to complete the lathe. Illustrated with photos and drawings to show you all you need to know about patterns, molding, casting and finishing the parts. The lathe specs. include a 7" swing over the bed and 12" between centers. Adjustable tailstock with set-over for taper turning. Adjustable gibs in sliding members and adjustable sleeve bearings in the headstock. A truly practical machine capable of precision work. Once you have a foundry to cast the parts and a lathe to machine them you can tackle more exotic projects.

Crafts & Hobbies

Exotic is a mild adjective when applied to the shaper. it will cut splines, keyways, gears, sprockets, dovetail slides, flat and angular surfaces and irregular profiles. and all of these with a simple hand-ground lathe tool bit. obsolete in modern industry, of course, because milling machines do the work much faster and cheaper. but you can't beat a shaper for simplicity and economy in the home shop. The shaper has a 6" stroke and a mean capacity of 5" x 5", variable and adjustable stroke length, automatic variable cross feed and graduated collars. You will be proud to add this machine to your shop. Especially designed for the developing home shop, it is a horizontal miller, but it has the full range of vertical mill capability when used with the angle plate on the work table.

If you can build a sand castle or make a mud pie you can make a sand mold to produce castings for your metal shop projects. It really is cheap and easy with a simple solid fuel furnace. Here are plans to build the melting furnace and instructions for basic pattern making and molding to get your shop project under way. Charcoal is the fuel and aluminum and zinc alloys are the metals to cast. None of the pulsation or roar associated with gas fired furnaces. Build your own molding bench and flasks. Make your own melting pots and most of the simple tools required. Discover how cheap and easy it is. Even if you already have a lathe and other equipment this simple foundry setup will greatly expand the capacity of your shop by providing you with a supply of cheap castings for your projects. Discover why so many shop hands say "Metal Casting has opened a whole new world of shop experience". Heavily illustrated with many photographs that will show you step - by - step how to build a foundry.

Building A Gas Fired Crucible Furnace

Sheet Metal Technology is written in Dave s unique style with the beginner or vocational student in mind as he demonstrates how a product idea is conceived, developed and then produced by a single craftsman with basic tools. Subjects covered are safety in the shop, use of tools, layout and pattern development, various ways of forming and joining metal along with edging methods, corner systems and panel reinforcement. You will be introduced to the basic sheet metal shop where you will learn about various methods of forming sheet metal and in some instances even constructing your own tools including a rather unique and functional 24 leaf brake constructed of hardwood. The final chapter opens with a mass production operation set up to demonstrate the efficiency and economy of modern industrial technology. Then further projects are progressively introduced as skill is acquired. Such projects as a dustpan for the shop, a handy tool tote tray as well as plans for single and double hinge tool boxes. By this time you are an advanced student and ready to construct the unique portable charcoal grill and the impressive three drawer tool chest from the plans provided. Dave Gingery brings it all within your grasp and you will be amazed at what can be produced with tin snips, standard measuring tools and a 24 sheet metal brake.

The classic seven book series by Dave Gingery is now available in a special hard bound edition titled, 'Build Your Own Metal Working Shop From Scrap'. This collector's edition contains the newly updated and complete 7 book series including; The Charcoal Foundry, The Metal Lathe, The Metal Shaper, The Milling Machine, The Dividing Head, The Drill Press and The Sheet Metal Brake. 
Build Your Own Metal Working Shop From Scrap is a progressive series of seven projects. Beginning with a simple charcoal fired foundry, you produce the castings for building the machine tools to equip your shop. Initially the castings are finished by simple hand methods, but it is not long before the developing machines are doing much of the work to produce their own parts. It does not take long to learn the simple craft of pattern-making and sand molding. Each project phase increases your knowledge and skill. There is no need to look for outside help. You can do it all in your own shop. No complicated math----No exotic equipment required----No large cash outlay. Lots of work to be sure, and some of it can be downright tedious, but the reward will be a practical small scale machine shop that you might never give yourself permission to buy, assuming you could afford it.
