Hi everyone,
I'm hand making long springs. And I'm having trouble - they wind well but as the spring gets longer, it becomes as if it's trying to fold itself over. I don't know why, and I would really appreciate any help with this issue!
Here is a video of the phenomena:

Yes, the mandrel size and resultant spring size are correct.
The spring is simple circular shaped coils.
The wire is simple circular cross-section music wire.
More detailed info:
Can you see how at the beginning end (left side in video) the spring behaves normally, but further up (as I wound more coils) when the spring is pulled a bit, instead of it gradually opening up, first it just pulls itself sideways, flattening the spring basically. Like it's getting squashed. Like the plane of the circular coils are trying to align with the axis of the spring, instead of being perpendicular to it.
Only after applying more tension to the spring does it 'pop' back into proper shape, and look and behave like a normal spring (like a slinky for example).
Anyone ever had this problem or know what is causing it and how to fix it?
Many thanks!
