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
