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" sheet metal brake constructed of hardwood.

If your hobby is amateur radio or electronics you will often need coils in a variety of size, type, specification, etc.. Coils are no longer as easy to find as they were 20 years ago so you will have to wind your own. With the help of this simple yet detailed manual you’ll quickly build a machine that can wind universal and honey comb coils, single layer and multi layer solenoids, close wound and space-wound coils, and pi-spaced coils such as those used for r-f chokes and transformers. And the mechanical counter gives you total control of accuracy.
Using castings from your charcoal foundry (see Book 1 in the series: 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.
