You could try to describe what you have. It may now go by another name.
In metal machining, some people use a precision ground cylinder as a 90°
reference on a surface plate. Let's say the cylinder is 3" in diameter
and 6 inches tall. If the ends are faced perfectly, then, when stood on
end upon a surface plate, the outer surface of the cylinder is at
exactly 90° to that surface plate. Is that what you are talking about?
If not, then what?

Years ago I bought a tool called Circle Square from the inventor here
on Rec.Woodworking. Over the years it has been my favorite marking
and measuring tool. If anyone knows the inventor of this tool, could
you post back here with any kind of contact info you might have. I
would really like to pick up another of them or two. It has held up
really well, but I live in fear of the day I drop it or somehow
accidently break it.

Thanks
