A Centerless Filing Button

I don't know why, but I have a facination with forming rounded corners on flat stock. The standard way to do this is with a filing button. You drill a hole in the stock, run a bolt through the button and the hole, and add a nut to secure the assembly. Then file down to the button. That hole really bugs me. I did figure out a way to avoid drilling the hole by using hot glue to secure the button. That didn't satisfy me so I kept thinking about the problem. Can't say that I'm done with this journey, but here is my latest "day trip" - a tool that lets me cut a nice 7/8th inch radius in sheet stock. No hole is drilled and no glue is used.
