#33 삼각함수대입후한번에마킹해서원하는사이즈시카고밴다로s밴딩접기(feat.초보자도쉽게가능)

Hello, I'm Pengchi Dasulja. The weather is incredibly cold. They say there's been a lot of snow, so please drive carefully on snowy roads and take extra care of your health. In this video, I've shown you how to use the Chicago Bander, not the S-Bend method I used in my previous videos, but instead apply trigonometry to mark and fold the band in one step before bending. With this method, even beginners can easily create the desired S-Bend size. I'm a beginner with this method, so I've folded it many times. As a beginner, please let me know if there are any errors or problems in the video. Thank you for your help, Choi Seon, and Jeong In-ok's questions. I learned a lot. Thank you.^^ #Trigonometrics #SteelPipeSbending
