How can I get the best boards?
Once you know what kind of wood you want and the size of boards you need, it’s time to buy your lumber. But you don’t
want to just grab the boards that are easiest to reach. Take your time looking over the available boards and check them
for these common defects. Ideally, you want every board to be flat and straight. You’ll probably have to work around
defects in some boards, though.
Flat
Ideal
Faces are flat, edges
are straight. Can
easily be cut to any
size.
Cup
Faces are not flat
from side to side,
edges are straight.
May be able to rip
narrow pieces that
are fairly flat.
Bow
Faces are not flat
from end to end,
edges are straight.
May be able to
crosscut into shorter
pieces that have fairly
straight edges.
Crook
Faces are flat, edges
are not straight from
end to end. May be
able to crosscut into
shorter pieces that
have fairly straight
edges.
Twist
Do not use
Faces are not flat,
edges are not
straight. These
boards are beyond
saving and shouldn’t
be used.
