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.
