Coil bind wasn't a problem.

Springs can do weird things when mechanically excited.
A good example may be a Slinky.
Hold it up so it's stretched out fairly well, strike it gently with a screwdriver or metal rod.
Take note of the oscillations produced.

It's especially interesting to press the upper end of the Slinky to your ear, strike it and listen to the jangling noises it makes.

High speed motion pictures have shown valve springs operated at high speeds do some weird things.
No small wonder they break.
