Tell me you are kidding.

22.5

Here is the way to figure any of these questions

For every side add 180 degrees, after 4 sides. example 6 sides....360(for
the four sides then 180 (for fifth side) + 180 (for sixth side) add
up...360 + 180 +180 =720 Now divide by number of sides....720/6
=120...divide 120 in half because you are mitering 60 degrees.



Now let's try it on the 8 sided table.


360 for the square + 180 + 180 + 180 + 180 + 1080

1080/8= 135
135/2=67.5 degrees If you flipp the board over it equals 22.5 degrees.

Geez you made that complicated. The simple equation to any sided table is
simply take the number of sides multiply by 2 and divide that number in to
360. Period.

More simply put, 360 divided by double the sides.

360/(4 sides x 2) = 45
360/(8 sides x 2) = 22.5
360/(60 sides x 2) = 3

Wrong

A 6 sides table would require 30 degree cuts. 360/ (6 sides x 2) = 30

I'm not sure which is more intriguing: the fact that the question was
brought up by a "woodworker", or the confusion it has engendered in this
thread...

180 / (number of sides) has always worked for me. What's with all the
complicated equations??

That will work. The math is how to get there.

That will work also but for me it is easier to remember 360 as that forms a
complete circle vs. a straight line. Actually 360 divided by the total
number of cuts works also.

Which of course is the same thing. 30 and 60 degree angles are
complimentary.

And on top of liking each other, they're "complementary" in forming a
right angle...

Actually you probably are not going to find a 60 degree setting on any saw.
So uh you would set to 30 degrees.

Gotta hand it to you, you sure know how to make things complicated.

Asked and answered just recently, so my first impression was that this
is a troll. A Google would bring the result. However, since it has
been answered several ways, I'll suggest yet another method, still
based on the same principles.

8 sides = 8 triangles to the center.
The center angle is then divided 8 ways = 360/8 = 45
Each triangle has two angles at the outside that are equal, and the
angles in a triangle add to 180, so they add to 180 - 45 = 135. Being
equal, they are each 67.5 degrees.

Do the same sort of calculation for any number of sides [oteh thsan
8.]

As you can see by using math you've come up with a completly wrong answer.
By using common sense the angle for the skirt cuts would be 22.5. This is
not rocket science.

Which as I mentioned to another poster is the same thing.
22.5 and 67.5 are complimentary angles. It's just a matter of which side
of the line you're cutting.

You've the wrong "compliment" here (BTW, I didn't post until after I
read the second time, just to be sure...).

Angles are "complementary", we give each other "compliments" for good
work, etc., ...

And I will mention again that you will not find 67.6 degrees on your saw.

What saw are you using? All of my saws have a range of 90 degrees to
45 degrees (maybe a little less in some cases) To get 22.5 requires
cutting a complementary angle or using a jig.

If the table top is accurately cut, then 22.5degrees

As stated, this question cannot be answered, as there are infinitely
many possible arrangements of 8 sides which result in a closed
surface.

However, assuming that what you really meant was "I want to make
an octagonal table top", the answer is 22 1/2 degrees.
