Indent That Center point

Use a sharp pencil and small combination square to mark diagonals to mark the center point on one end of a pen blank. For dark woods, intersecting lines marked with a Sharpie can be easier to see than pencil lines. Clamp the marked blank and indent the marked center point with an awl or center punch. The indentation allows the point of the bit to self-center over the indentation when drilling the hole for the barrel.
