Circular logic points to the center
I was recently working on a project that required a centered hole in one end of a 11⁄4 " dowel. Lacking a tool to help me find the center, I resorted to pencil and paper.
I traced the circumference of the dowel on a piece of paper, then cut out the circle. By folding the disc into quarters, the intersecting folds located the center. I placed the disc on the dowel end and pierced the center with an awl.
