news:Nd-dnTXsqcjDl3TfRVn- How about forgettng the joiner and hand plane one
side roughly flat . The
easiest way I have found to do this is to use a scrub plane across the
grain.
Having done this run it through a planer with the just flattened side on
the
bed . Keep runnung it through the planer until the whole side is finished
.
flip and resurface the rough handplaned surface. Now leave it for a few
days to let it stabilize, then recheck for flatness , if not, repeat the
process until it is . don't forget to store when complete upright or at
least where both sides get the same air exposure .....mjh


Less the "keep runnung," the way I do things. Nonetheless, if you have
strongly curved annual rings in one area of the board, smart money breaks
the continuity.
