I can just grab a piece of tool steel and go stand in front of the
grinder for a while, but I was wondering if there is a simple
elegant, not over priced tool to do the job. Ring groove will
likely be 1.1" give or take.

The ones I bought in a second-hand tool store look like the CoroTurn
XS, ground from solid rod.
