The sketch at the right (Figure 1) shows the initial positioning of the board
to be edge trimmed. The concave edge of the board is placed against the fence.
The convex edge is trimmed off by pushing the board past the tablesaw's blade.
The board is then flipped over, with the freshly cut side placed against the
fence. Next, the fence is adjusted so its distance from the blade is equal to
the width from the freshly cut edge to the narrowest portion of the concave
edge of the board. The board is then pushed through the tablesaw blade and the
concave portion of the board is removed. The remaining board is straight and
true on both edges.
