Imagine a very shallow "V". I noticed while cutting some 2 x 2's.
Put a straight edge on it and the inner portion of both sides is about
1/8 inch back from the straight edge. So far I haven't found the
manual, but the whole fence is one piece of cast aluminum and I can't
imagine straightening it. Any ideas? I tried wedging the center
portion forward but it lives up to it's name. It is extremely ridgid.
