Hand Plane Chatter

[William R. Monroe]

When planing a curve such as this, if you are planing with a concave sole, 
you will plane down from the apex on either side of the workpiece, working 
with the grain in both directions.  Obviously some overlap must occur at the 
apex to finish things off well, but essentially you shouldn't be planing in 
one smooth motion from end to end.  Problems worsen the more convex/concave 
your workpiece gets.

Similarly, if you are planing with a convex sole you will plane into the 
nadir, the bottom of the curve, from both endpoints.
