   67.5 degrees is 22.5 degrees from 90 degrees (a right angle). Set your saw to 22.5 degrees. Practice with some scrap wood before tackling your project. Good luck.

   InletJoe,

   It's easy to forget that the when zero-degrees is indicated on your "chop saw" it's actually set to cut at 90-degrees to the fence (I haven't yet heard a reasonable explanation for this bit of labeling mischief).

   In any event, to cut octagons, set your saw for 22.5-degrees, make cuts on a few test pieces, and verify that they sum to 90-degrees when temporarily joined and held to a framing square. Adjust your cutting angle if the sum isn't 90-degrees, make more test cuts, and ensure your miters are tight and clean before you commit to cutting your work pieces.

   Good luck,

   Whether you think you can, or you think you can't, you're right.
