For a Dutch presentation, visit: https://www.designuitinspiratie.nl/singer-electronic-560-spoelgaren-modificatie/ While tinkering with my mom's 40-year-old Sewing Machine, I made some modifications. One of them is a new Spool Holder that can be swapped out for the old one. Now it's possible to use up to four threads at once. Why would I want to do this? I enjoy experimenting with different thread colors. They create nice color effects in various light conditions. In my experiments, it worked up to seven threads at a time. Four pass through the needle and three wrap around the coil below the needle. Note: I had to remake two gears because the teeth were broken (please ask if you want more information about these gears). PET-G appears to do the job since they're still functioning. Be cautious when using more than two threads; it's not recommended. Maybe someone online can also utilize the Spool Holder. If you have any questions, feel free to ask.
