suggested explanation Explanation: It's hard to say much without seeing the actual equipment or good pictures of it, but in a mechanical context a spinner is something that rotates (or can be rotated) relatively freely about an axis. One example you'll find in the dicos is the cap on the hub of a propeller to streamline its shape; another is a device that was formerly used (until around the 1960's or so) to attach the wheel hubs of racing cars to their axles (much faster to dismount and mount than with a conventional set of lug nuts). A third example (and probably closer to what you have here) is a tool resembling a screwdriver but with a recessed socket at the end of the shaft, which is used to quickly thread nuts onto bolts (or unthread them, of course). In your case, it sounds like it is a power-driven mechanical device that spins a rod or set of rods to thread them together or apart (faster or easier than doing it by hand). |
