After deciding on the Grizzly G0463 Mill/Drill, it's time to pick
out a small lathe.

Rules of the game:
110v
Moveable by mere mortals down stairs
Must be able to cut 56TPI threads (used in old Winchester rifles)
Spindle bore of 1" or better
Distance between centers of 24" or better

Q: Would being able to feed and thread to the left be worth it?
