    Hello all, 

    Hydraulic Die Forming for Jewelers and Metalsmiths by Susan Kingsley
    has an excellent chapter on blanking dies. She gives very detailed
    instructions and includes a table in the back of the book that
    determines angle of cut based on thickness of tool steel and
    sawblade. 

    Sawing blanking dies is really very easy. It just takes a bit of
    practice. I have a drill press with a tilting table that I c-clamp a
    bench pin to. A magnetic protractor ($10 at my local hardware store)
    tells me the correct angle to tilt the table. I have a small painted
    drill bit inserted in the chuck that I use to check my saw blade to
    insure it stays at 90 degrees. I have learned to lock my elbow and
    use my shoulder when I saw to keep the saw blade steady. 

    I blank out pieces of silver and gold 26 and 28 gauge. I have never
    had to heat treat a die, perhaps because I use such thin metal. I
    have some dies I have used for 8 years and blanked out thousands of
    pieces from. I didn't have a hydraulic press when I started. I
    placed my die, with metal inserted, between two sheets of 1/4 inch
    tool steel and pressed the "sandwich" in the jaws of my bench vise. 

    I hope this info will motivate any of you who have wanted to try
    this technique but thought it might be too complicated. It opens up
    so many possibilities for working in multiples! 

    Best regards, Jayne Redman
