Once the stencils are done, use a pencil to mark the bottom edge of the letters on the stencils as well as the centre of the letters and the distance between each letter on the side panels. Then position the stencils in a row on these markings, fix them in place with screw clamps and set your router with the copy ring into the stencil. Now sink the milling machine into the wood and start on the stencils, letter by letter.
Tip: If you want to cut the letters all the way through instead of just milling into the wood’s surface, you will need to leave a connector in closed letters like “A”, “O” and “B” so that the inside of the letter doesn't fall out.
