    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.

    I am going to make one at some point. Plus a few other things. Right now I'm busy modifying a 12 x 20 metal building that will be my metal shop. I currently have my metalworking tools in my garage. There is almost no room left for all the stuff I have in there. I have a woodworking shop already. It's 10 x 16. It's roomy enough to work in with just my woodworking tools but I have other stuff in there that will eventually move to the garage. Slowly but surely.
    Stupid is forever, ignorance can be fixed.
