Ok Guys been absent awhile and back to carving again. Or trying. My mind fails me sometimes. Im trying to figure out a good depth to carve into the wood for like a sign in .75 thick board. I tried it 2 times to adjust it but one come out like I was writing with the tip barely scratching the board and then the other was just a little deeper. I hate messing up wood as its not cheap! Thanks for recommendations.
