The machining processes in making a 1 off banjo bolt. Including using the Ainjest high speed screwcutting attachment ( or "rapid threading" attachment), which could have been a bit quicker if I'd been paying attention & set it up properly !

Sometimes the customer just has to pay custom part price.👍
Was that an optical illusion that the twist drill was running backwards?😕

You often see cutting tools or even lathe chucks apparently spinning the wrong way in videos, but in this case I flicked the switch into reverse to stop the spindle & it did actually run backwards for a few turns!
