Hey! I know this guy. I prefer a straight threading, I think this would actually be less maneuverable/manageable on extremely tight working quarters, but that's just me. Always good to see little 'tricks' like this that may be obvious to some, you can always adapt them for your own uses.
Also, I think you might be a little off on your length estimations, KQ. That was a little short for an inch
P.S. Nice machine.
