Anyone know where I can find a 1/2" shank bullnose radius router bit that will cut a bullnose (or bead, or whatever the term is) that is exactly 9/16" from top to bottom? The bullnose will be cut on the edge of 3/4" stock. I've searched all the usual sources and beyond but cannot find one. I need 9/16" to match an existing piece of furniture. It is the molding trim on the aprons of a Thomasville dining table from about 35 years ago.

Thanks for any info!
