Although each manufacturer has
a different name for this chuck
accessory, adjustable bowl jaws
all work the same. Resilient grippers
hold the bowl rim to the chuck jaws.
Sets cost from $50 to $140.

Back to the bottom

For a bowl gripped by a spigot, reverse-chuck it, gripping the rim with a shop-made jam chuck or accessory adjustable bowl jaws, as shown above. Then turn away the spigot, and form a slight recess in the bottom of the bowl.

Very informative! Metalworking 4 jaw chucks work differently, but that is another ballgame.
