Agentgates´s TPU setup with strange wavehill hump

Great animation, Broli.
However, your winding direction seems reversed from the prototypes. See picture here:

The wire go from left to right and from bottom to top on the OUTSIDE, then they go down on the INSIDE.
Isn't it ?

I has some fiddling to do once i got all the way around. I thought that an od no of top and bottom pivot points would help alter the transitions.

I have not wound a coil yet but I have followed this thread completely.
My observation is this. When we start with a 45 deg. angle and keep it along the sides inner and outer but at top and bottom it is changed 90 deg.
It seems that with the cardboard pipe it really likes to flow around the corner in a more straight line.  45 to 45 to 45 angles.

The fiddling is want I encountered too, and that started me thinking.
It may be that the asymmetry is required on purpose, but I have feeling that symmetry would be better.

@Tony: how did you solve this yourselve? Did you adjust the angle every time you reached an occupied angle?

@  Broli
Awesome instruction!
One issue I encountered during my coil implementation:
If you use exactly 45 degrees, then after 4 time up-down winding you end up exactly at the beginning angle. This means if you want to continue, you have to make one winding at 55 degrees or 35, which disturbs the patron.

In the picture below I am trying to visualize this issue.
Each rectangle represents 10 degrees of the circle.
You can find 36 rectangles in total, representing on circumference of 360 degrees.
The black lines are according an angle of exact 45 degrees.
The red lines use a 50 degree angle.

The red lines will use same angle every time while the black line needs once a 360 degrees a different angle, which disturbs the symmetry of the coil.

Yes that is correct  I did not hook end of the first winding to the start of the second but it should not disturb the pattern too much, 1/4 of the outside wires would be shifted 10°. I would be happy enough if this gave some OU maybe later on we will discover more efficient winding combinations and so on.  For instance I discovered that if you use 40° instead of 45° you must rotate the pipe twice before reaching the starting point. Perhaps this can be expanded on later on to use 1 single wire that goes 9 times around before coming back at the starting point. This would have no "artificial" shifting issue. This would need some basic discrete math.
 

Great animation, Broli.

Correct me if I'm wrong but the winding direction doesn't matter, if you flip the coil upside down then it will have the "correct winding". Just like looking at a clock from its back will make it go counter clockwise from your point of view. What's more important is the secondary winding direction and polarity.
