Fractional Center Finder

This is the Fractional Center Finder with build in lubrication system (TDI).The stoppers on each side are vertical print-in-place axis that rotate and sit flat on the piece you want to mark.

Like this you can not only draw a marking along the very center of your workpiece (at ½ ) but also draw 2 equally spaced lines (⅓ and ⅔ ) or divide it in 3 sections (¼ , ½ and ¾ ). The graphic below explains the concept further: The Fractional Center Finder comes in 2 sizes. There is a smaller 8 cm version (on plate 1) that works with any width up to 8 cm (3 1/8 inch) and a bigger 12 cm version (on plate 2) to work with big beams up to 12 cm (4 11/16th inch).
