This is my latest woodworking project. It was, needless to say, lots of fun to make! :-) Here’s how I made the box:

I built a prototype with piece scrap and then decided I would try to make a more finished project. I cut my different types of wood to the right thickness and then glued them together, after that I planed one side flat. I cut off the other side to exact size on the table saw. I setup a stop block on the miter saw so that every piece is the same size and then cut eight pieces. I glued up the box by taping the all of the outside edges first and then gluing the whole thing together. I built the bottom using the same basic idea.
Note-
Set your saw to a 22.5°angle for octagons. On your saw usually 0° = 90° and thus 22.5° will actually be 67.5°. If you wanted to make a different sided box all you would have to do is divide 180 by the number of sides. For Example – 180°/6(six sides) = 30° or 180°/18(eighteen sides) = 10°
