inside of deep bowls. what have you tried and what seems to work the
best for you. do you cut or scrape - angles of presentaion and angles
of grind ?

Cutting offers the best chance of taking a narrow shaving, minimizing grain
pickup. "Shear scraping," which is cutting without benefit of bevel does
pretty much the same thing. Flat scraping will bend fiber of necessity, and
must be done with a very fine touch to minimize chances of digging in which
a bevel would take care of.

You have to be steep enough on the bevel to get the nose of the gouge inside
and the bevel in contact while not hitting the opposite rim with the tool as
you enter. My thicker bowl gouges are ground to longer bevel angles than my
thinner, because they don't have to get into narrow spots.
