Wimshurst Electrostatic Machine

thingiverse

A Wimshurst machine print project is presented that uses homemade bearings and repurposed parts. To minimize charge leaks, avoid straight metal edges where corona discharge can occur. Safety precautions are necessary when using large Leyden jars, as high voltages may be present despite minimal current. A YouTube video (link provided) demonstrates the machine in action. The Wimshurst Workshop website offers a tutorial on building the device. Print all necessary files and assemble two discs with 48 sectors each or use acrylic rotors for added precision. Copper BB pellets serve as bearings, and motor adjustments may be needed depending on print quality. Aluminum tape is used to cut sectors, while copper wire forms collectors with springs to transfer charge to Leyden jars made from Kapton tape. The spark gap utilizes printer forks or balls, and conductive spacers connect the gap to capacitor plates. Assembly is straightforward, and this project serves as a proof of concept rather than a perfect machine, encouraging experimentation.
