Notes If you use a small dish bit that has turned edges it will leave a up grain effect at varying spacings, this is one way to get the effect... Another way is to use a flat bottom bit and use 2 colors alternating the depth.. There are many different ways to create effects, just visualize the cuts... I have used a 1/2 bull nosed bit to create woodgrain on one job it worked well, I alternated the depths and it was a large open sign.. good luck and have fun expirmenting Dan Hammerstron..
