I recently made a china cabinet with large curved doors requiring a 30″ radius. Rather than spend the money on a specialized routing attachment, I improvised and used two 36″ hardwood dowels fitted into the holes in the baseplate of my router. At the other end, I fashioned a hardwood block with V-shaped grooves for each dowel. Two screws tighten the blocks together, and the middle screw acts as a pivot.
