    I agree! 

    Besides, it would be useless. The JB Weld would eventually wear and
    the holes would become sloppy - perhaps worse than they currently
    are. The amount of pressure that you can put on the pins by cranking
    the screw is very high. You need a properly fitting brass or steel
    pin. 

    By the way, we rarely use all those fancy pins, attachments, and
    fixtures that are sold by the jewelry and engraving suppliers. Most
    are the wrong shape, or - in the case of the pins - damage the
    article being engraved. Don't waste your money... 

    95% of the time we use leather, rubber, neoprene, urethane, or soft
    wood pads between the jaws. (I even used to use lead sheet when I was
    a puppy, but that's not done any more...) 

    Formed to fit fixtures are made of pitch, shellac, hot glue, Bondo,
    and the various new thermoplastics. These are used directly between
    the jaws or on top of pine wood blocks. The larger blocks for holding
    awkward shapes have a "T" profile. On top is your fixtured work, and
    the center leg is between your jaws. 

    Really the only pin type fixture used regularly are those I use to
    hold rings. And most of those are made here in the studio and are not
    available in the fancy kits...
