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.<br />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.
