A question for experienced free-handers. I notice almost invariably from the scratch patterns that I'm not hitting the corners of my blades and chisels as much as the center when I'm working on the backside. (I've check for flatness to .004 before starting and I found it still happens. ) I try adjusting my technique to add more pressure to these areas and eventually I even out the scratch pattern. Now I'm wondering if my adjustment just results in creating a slight camber that I don't want. Maybe I need to adjust my technique in a different way to get consistent amount of pattern? I raise this question because I sometimes end up applying so much extra pressure that I've started trying to work out other causes.

Thanks for any pointers!
