Thicknessing vs. Planing
A few weeks ago I stumbled across the website Woodgears (woodgears dot ca) and found plans for a thickness sander. Since then, I have seen a few references to "thicknessing" wood. So, my question is, what is the difference between "thicknessing" and planing wood? Aside from the obvious that one method sands the stock down to a certain thickness and the other cuts... I am wondering if there is a difference in the end result. If, in general, one method is preferred over the other.
