I think it's safe to say that I can now effectively do enigmas.
I've found that by lining up my cores and getting them perfect that I can run through a whole piece (10") of enigma wire on full speed on my drill, around 1800rpm's without having to secure the cores anywhere along the stack.
Wrapping them though is a very delicate operation.
Too much pressure when holding the wire will collapse the enigma under your fingers.
If you use any part of your finger nail you'll open up the enigma and reveal the ribbon stack underneath creating a huge gap between the enigma fuse.
This is just a quick pic from last night.
