Nautilus bdc coils rewickable?

[Leon1972]

So I'm a little confused. I keep reading the nautilus coils are not rebuildable yet I found this video that rebuild them. Are these the same coils or different coils from the nautilus bdc?

From watching the video it definatly seems he was rebuiding a BDC coil.

That's what I thought. Strange so many posts about it not being rebuild able

Actually it seems pretty easy to fully rebuild this coil. As I'm not every mechanically inclined and I could screw up even this what are the inherent risks I can get from rebuilding this incorrectly?
