    Default needing a mathmetician again.Chevron box

    I have started a new box and calling it a chevron design which should align the timbers to all sides of the box.

    The box is intended to be 230mm along the longest side by 75mm high.

    So the centre line should be 115mm (as will the ends)

    using a protractor I got an angle of 32.5 degrees to cut strips what is the exact angle using maths please?

    each numbered piece represents a different timber species.

    those lengths look very handy as well, any amended drawing would be much appreciated.

    Many thanks to all.

    Printed out and ready to go.

    I have had my first stuff up. Putting some Sycamore through the bandsaw it wandered all over the place. But not to worry I will straighten it out on the TS

    You should change the length to 232mm as well to get even figures that way too
    Cheers

    Default Chevron box

    I have no problem finding the arc tangent of the two figures, whatever they end up being but as a woodworker I need a lot of advice.
    If I were to do it, I would glue the four strips together, cut the diagonal of the appropriate length and then cut the other side at 90 degrees (as per sketch). Even better if I can manage to cut two at once. Any problem with that?
