Complex threaded loose nut piece machined from a single part - photo

I'm intrigued, what are the traps with the parting off, wouldn't it be relatively easy to position a rod for the cutoff part to fall onto to avoid getting spun by the minor diameter ?

Just chamfering the edges before you part off. No chance to flip around later. Any smoothing out of what you have sone on the nut will be a little harder than normal. Just takes thinking all the operations through before you go for it.
