How to find the center point of a circle
FrizzleFried:
If you have a compass, simply set the compass to draw the same sized circle you have already drawn...take a couple of test swipes...yup...same size...good...the pin----tallywhacker--- in the middle where you set your compass down to pivot is the middle...sheesh.

And if you don't have a compass then draw a straight line any where in the circle, find the middle of that line and draw a perpendicular line, then measure and find the middle of that line, done , thats your center, no compass needed.

Draw a line square to the side of your cp where you want buttons. Measure out a distance on the line how far apart you want your buttons (this will be the center of the button-circle). Now with a small drill, drill out a hole. Now use your hole saw or better yet forstner bit to drill the hole.

Cut out a paper circle the correct size , fold it in half and then in half again and maybe once more .
Now cut off just the small tip and unfold , voila your center spot is ready .
Stick that on your original circle and mark the middle hole with a pen marker .
A minute work .

Dunno, I just start by drawing the circle in AutoCad and dimensioning with a center mark...
