I have an old shallow kitchen cabinet that was probably in a corner - anyway, it's missing a mitered piece of molding at the top, which is profile milled similar to a cove molding, i.e., a rounded "groove". Now I'm wondering: how can I create something similar the easiest and cheapest way? I have access to a hand router, workbench, chisels, and several planes.
The dimension of the "radius" of the milled profile is about 18-19 mm, and the entire molding is about 22 mm thick. The piece to be attached is about 200 mm long.
