Quick, well explained, easy to follow, simple.... thank you for this little video. It is exactly what I needed at this moment in a project I'm working on.😊
Hello, you can calculate it. Attach two cords; measure one of the outer cords; make 1cm of spiral; measure the same outer cord again; how much shorter is it? That is how much length you need on the outer cord for 1cm. Multiply it by 60 to work out how much length you need on each outer cord for 60cm; I would add on another 10cm or more for attaching the cords and some leeway. The middle cords should be 60cm in length after you've attached the cords. So if 1cm of spiral uses 10cm, then 60cm of spiral will need 10cm x 60 = 600. Plus 60cm for the inner cord. Plus an extra 10cm or so to attach the cord and some leeway. Total is 670cm. So in this example, you would need two cords at 670cm. Attach the two cords and ensure the middle cords are both 60cm. The outer cords are longer.
