Above shows the progression as the red was added. Notice that instead of one stencil with all of the red, the 'sevens' were a separate stencil. I painted the outline first and then added the sevens. I took measurements so I knew where to place the sevens in relation to the outline.
Here I am adding the white which surrounds the sevens and then a picture after the painting is done.
The final two pictures show the finished result. The first is before I removed the tape from the rails. The last picture is of the machine after it was put together.
