hmmm, are you sure it was the crimp and not just the load? But yes, too deep a crimp.

I'll be using a vice, not a hammer, so more control. Does somebody have instructions/advice for using these things? Should you do a partial crimp and then rotate?

The load is the cause of the heat, but only because the crimp is defective. It should carry the same load as the cable. There are different kinds of 'crimps'. One chould argue that this 'crimp' stretches the metal, not compresses it. A good hex crimp literally compresses and re-shapes the metal itself (think Superman and coal= diamond). If you start making multiple compressions on a vise, I think you stand an excellent chance of fatiguing the metal and splitting it.
