3/8 for a mini. I'd get a 1/2" detail gouge first, though. Better at
hollowing.

M2 will do, powder is nice.

Hi, newbie here...

I'm selecting a bowl gouge, but am somewhat unsure as to the best
width to get. My primary interest is in turning small boxes (8") and
segmented vessels (10") on a Jet mini-lathe.
