The Wireless Connection

It would difficult, if not impossible, for one person to author a column such as this without eventually running out of material, original ideas, or projects. I’ll admit to being at the end of my rope more than once as deadlines loomed and a very anxious Editor-In-Chief Harold awaited my material! Thus, I often turn to reader’s letters, or to the Internet, in search of fresh column material. So it was when I first heard of Sylvain Vanier’s plans to make reproductions of early dog bone resistors in his home workshop via an Internet newsgroup, I knew that this was something worth sharing with you! Sylvain is a gentleman of many talents, and I was elated when Sylvain agreed to allow his material to be presented in this edition of the “Wireless Connection!” Here’s Sylvain’s technique for making reproduction dog bone resistors, including step-by-step photos.

Reproducing Dog Bone Resistors

This article describes the technique used to replicate antique resistors, known as “dog bone” resistors. If done properly, it will be nearly impossible to tell the reproduced part from an original.
