Making an octagon: I'm going to assume you're using square stock. If it
isn't square, make it that way. Divide the length of the side of the square
by 3.414. measure that amount in from each corner, giving you two marks on
each side. Connect the two marks from each corner to each other, giving you
a triangle. the area inside the marks will be a regular octagon.

• Work from the outside dimensions of a square that is as wide as you want your octagon to be. The outside measurement of each side of your octagon will be 1/2
Message 4 of 15 , Aug 4, 2004
Work from the outside dimensions of a square that is as wide as you want your octagon to be.  The outside measurement of each side of your octagon will be 1/2 the length of one side of your square.  The angle cut will be 22.5 degrees.

I think...........?

Good luck

Yes, it will. From the old corners that get "moved in" by the cut, you make
the angle more obtuse by 30 degrees, giving you a 120 degree corner. the
new corners created out of the centerline of the stock start at a straight
line(180 degrees) and are made more acute with two 30 degree portions
removed, so they are also 120 degrees in the end. equal angles = equal
sides, so you have a regular hexagon.

> anyone know how to get a hexagon pole?

I think it was said earlier.... All polygons add up to 360 degrees.
If you have 6 sides, each of the six angles must be 60 degrees.

To lay out a hexagon on the endgrain, find the center and draw a circle
using a compass. Set the point of the compass on the line somewhere
then scribe another spot on the circle. Move the compass to that point
and repeat all the way around and you'll come up with six points.
