Here is a mantel clock that is simple to cut. I used 1 inch thick walnut for the body of the clock. I laminated 1/4 inch maple to the back. You want to use the same contrasting wood for the front and back to give it visual balance.
Apply the pattern to the body of the clock and use a hole saw to cut the 3 1/4 inch hole. Then glue the back contrasting wood so the hole is not visible from the back.
After the glue is set cut the pattern at the scroll saw.
After you get the scrolled front fretwork cut insert the clock and glue the fretwork around the clock. This makes sure it is aligned well.
The pattern has an optional crown. I did not choose to cut the crown because my wife did not like it. The crown adds another inch to the height of the clock. Your choice to include it or not.
Hope you have fun with this pattern.
