This center finder will help you mark out the center of boards for milling, or making mortise and tenon joints. There are 3 marking holes for either a Pica Pencil, .5 or .7 mechanical, or a Sharpie Fine Point marker for darker woods. There are markings along the side every 5 and 2.5mm. I have also included 4 different width centers to mark the width of your mortise (10, 8, 6 and 4mm). If there are requests I can make more. Comments and Makes appreciated. Happy Printing!
