Donn,

Like you I've carved tons of signs without anything like what's been shown. Using ArtCam Insignia with hardwoods, soft cedars, redwoods, MDF, and Trupan I can't remember any problems.

Those of us making a living at it move past errors like this with speed. Note all the suggestions with no photo examples. This is a visual business and suggestions are more effective if seen with a snap or two.
