Hi. I'd like to make an elliptical frame for a piece of glass that will be the top of a coffee table. The glass would fit into a rebate cut into the inside edge of the frame. I could cut that rebate with a router, but I'd prefer to do it by hand. This would be like cutting the ledge for edge banding on a guitar, only much larger. If folks could recommend a technique for doing this I'd appreciate it. It needs to come out very clean as it will show. Thanks. -Howard
