45 degrees


Cut each board at.........

Cut each board on both ends at 22.5 degrees and put together.This will
make your octagon.If you want to make a square frame with 4 boards you cut each board at 45 degrees.If you are using a miter saw you may have positive stops already set up for these angles....GOOD LUCK!


We already did this once

And though your miter box may SAY 22.5 degrees, it ain't so. The actual angle is 67.5 degrees. (It's 22.5 degrees off of true vertical or 90 degrees) If you've ever seen the military flag boxes (triangles) the flat portion is cut at 22.5.


Yep . . .

George is right,

The 22.5 is off vertical or if you look at backwards, it's the compliment to 67.5. If you were to measure an octagon angle with a compass, you'd find that it's about 67.5. Now, you can't just cut a 67.5 degree angle because you're matching the angle not creating it. See what I mean?

At any rate, a good tip is to always use some scrap material first and do a test run. Simple 2X4 scraps will work. Just don't "practice" on that land scape timber.


yeah!!

Like I said just set your saw to 22.5 and cut the boards......no need to get all crazy and high tech......sheeeeeesh.Oh and have fun...Bud


Symmetrical!

George is right, it is 22.5° from center (90°), but it could be either 67.5° or 112.5° as well. :) lol! Actually the DeWalt miter saw I have is centered at 90° and the angle would read 22.5° on either side. I hope this helps!

Just set the miter saw at the 22.5 degree positive stop and make your cuts. Don't let all of this other micro management discussion confuse you. It's easy, it's fun, and it'll work out great.

I've ALWAYS wanted to say that! CUR did an excellent "documentary" on the EXACT procedure for making an octagon box. Very in-depth and fairly easy to follow. Worth your time to read it. Have a good un'.

As all have sais 22.5 degree plays the trick but if your using big
beams be careful to mark correct the 1st time all speed sqrs are different but all wil be good enjoy the adventure
