Construction layout question?

Question

How do I go about making a template of a 4 foot diameter circle, where all intersecting lines are 7 7/8 inches apart at the tip of the circle. I'm making a wishing well and it says to start with the above template. The 2 x 4 "bricks" are to be 7 7/8 inches long.

Answer 1

Lay out your circle, then use a pair of dividers set at 7 7/8".  Walk it around the circle.  You may need to make it a bit larger, or smaller, to come out even.

Answer 2
