I am refinishing an old china closet that had several coats of ugly paint on it. The closet is curved almost equal to a half circle. There is curved glass in the door as well as both sides. Three of the top and bottom mouldings that hold the glass in place (there are 6 total) are damaged. How do I find out what the radius of the glass is so I can cut new mouldings out of a solid piece of wood? HELP!!!
