Veritas Centre Finder - Aluminium
Made from aluminium; Veritas' Centre Finder uses a knife-edged steel blade to score the end of a workpiece. You set a square or cylinder (up to 150mm across) in the marker; tap it with a mallet; turn the wood 90 degrees and tap it again. The result is two score lines that mark the centre of the wood. In soft wood the lines will be deep enough to hold the drive centre directly. You won't need to make additional intersecting saw cuts in the drive end of your workpiece.
