Maybe it's to keep the tool tip from bending left/right? The tip
isn't as
well supported as a 60 degree tool would be.

'Don't know. I think it's mentioned in the Atlas lathe manual, and maybe in
the South Bend _How to Run a Lathe_ book. But neither one, if I recall
correctly, says why.

I have a few really old, old lathe operating books, but they're in storage
right now as we juggle some family arrangements and I'm trying to make room.
