    Another optical ctr punch

    I made this about 10 years ago and have used it a lot, made from acrylic rod which lets natural light in.
    The two optics have a choice of cross hair or bulls eye (I find the bulls eye my preference) the holder has a set in O ring which stops it moving while changing from optic to punch. The punch is HSS from an old end mill and is only used as a prick punch deepened by a hand punch.
    The lens is turned with a form tool and is easily polished with any metal polish you have to hand.
    Forgive the poor image I only have a pocket camera, real time is much clearer.
