Hi Everyone,
I want to try a 6 axis 3D chevron. My blank is 50 mm. Circum..(there is no taper on this part of the rod) I have an under wrap of 180 mm in length. I have read custom thread art/advanced custom rod building- I understand that the spacing (center to center) for a single wrap is the same as the circumference and for a double wrap it is 1/2 the circumference. Question 1. What is it for a 6 axis ? 2. What are the starting dimensions along each axis? Thank you for any information! I have Billy's book on order! Re: 3D Chevron

Jon, Don't think of it that way, this is where you're going wrong. What you described is the end result of looking at a double pattern layout in total. Instead, think about each layout on it's own as if the other layout didn't exist. There's some understandable confusion among beginners about multi axis layouts. Think of it this way, each set of opposing axis use the same starting and ending points, and the same layout spacing, they just start on different axis. As you begin to lay threads at the start of each axis, they will spiral and cross the other axis' threads at points between the centers. On a 4 axis layout threads will cross 1/2 way between centers on the 90 and 270, on a 6 axis layout, threads will cross at 1/3 and 2/3 distance between centers on each 60 degree axis, and on an 8 axis layout threads will cross at 1/4, 1/2, and 3/4 distance between centers on each 45 degree axis. If you scroll down 37 posts, this was just discussed. Here's a quick link to the thread: [rodbuilding.org] To answer your specific question: If your blank doesn't have a taper, or you are going to ignore your blank"s taper, then the simple answer is you will mark all six axis at: the starting point the 1/3 of circumference point the 2/3 of circumference point and the full circumference point and repeat for as many times as necessary to fill your work area.
