For marking or making anything you want evenly distributed around the
turning.

I use mine for three-legged stands. Making the dovetails for the legs is
easy with a jig for the router.

I've done some minor work on a lathe for a year now, and I'm wondering
what
this indexing knob on the headstock can be used for...supposed to be for
fluting and reeding, but it seems to only lock the lathe preventing it
from
turning.
