What angle do I set my mitre saw to if I am want to make a 12 sided polygon.?

Question

I am in the process of building a 12 sided ferris wheel with 3/4" x 3" pine for the outside of the wheel. trial and error is really racking my brain and is not working out so far.

Answer 1

This will work for any kind of 'gon.



There are 360 degrees in a circle.

Each angle will be 1/12 of 360.

to make each angle you will use two boards.

so, 12x2=24 360/24=15

Answer 2

Each part is rotated 30 degrees from the adjacent component. Each part should be end-cut 15 degrees from a normal square cut. This would be a setting of 15 degrees on your miter saw.

Answer 3

15 is the answer...if you have 12 sides it will require 24 cuts...a circle is 360 ...divide by 24 cuts = 15 degrees

Answer 4

This project is too dangerous to attempt with a miter saw.You need a small band saw or a scroll saw.Scribe the angles on the wood first and clamp before cutting if you use the miter saw to be safe.

Answer 5

Are you using 2X4 for roof rafters? What are you building? Only engineered roof trusses are allowed to use 2X4 constuction. Yes 18.5 will get it.

Answer 6

i don't have a protractor handy, what i would do is draw what you are making then the angles you have you divide by 2 and this would be your angle

Answer 7

i think its 30degrees ...allthough there are 24 cuts each one sits alongside its neighbour ..so two are the same every time

Answer 8

22.5?
