The roll forming process from round tube to square tube

Best way to learn threading is by observing. That’s how I learned. In beginning it will be hard but as you practice it will get easier and easier. I will start sharing more about how threading work since so many people have been asking for tutorials. In this video someone was watching that’s why I was talking little bit but I was teaching / showing mostly when I was not threading. Time was limited 😞 . . . : #threading #eyebrows #satisfying #tutorials #fyp
