Very interesting   However, I've looked into modifying/using stepper motors salvaged out of duff equipment but came to the conclusion that it would be a lot more work and could even be more expensive than building from new.  With suitable stepper motors and driver chips/modules available online for a couple of pounds, I decided salvaging was just not worth the trouble.  Goes against the grain really as I'm into recycling big-time.

true, but that takes all the fun out of it
