The decade box is historically used as test equipment during prototyping to tune circuits. The wide resistance, and fine increments are what makes it useful. This 3D printed 117 Turn potentiometer project does the same for a fraction of the cost. bit.ly/3s26eWR

Please SUBSCRIBE 🔔 We have developed useful content to help the machinist community with gears and mechanisms. With our free resources centered around skills/tools/knowledge, you are now enabled to make any high quality gear you would ever need. Gears are at the heart of all interesting mechanisms.

The history of gears is surprisingly interesting - the process of milling and hobbing gears plus the transmission of torque and movement all find a place here. We will open the "Secret Gear Case" to YT as well through this channel - a personal mission
