    Using the Bonny Doon hydraulic press instead of a hammer or mallet
    makes cutting discs much easier, especially when cutting thicker
    sheet. There is no shifting, double striking or bouncing. The cutter
    goes down straight so you are less likely to bend or break your
    smaller cutters like you would with a glancing blow. With the cutter
    going down straight, there is less wear and tear on both the male
    and female parts of the disc cutter. There is less wear and tear on
    you since you won't be swinging a heavy hammer or mallet. 

    As soon as you cut through the metal (you'll hear a "sproinging"
    sound for want of a better description), stop and release the
    hydraulic pressure. Since you aren't whacking the cutting post with
    all your might, you're not slamming it home on the disc. There will
    be less damage to the tool and the resulting disc. NOTE: If you're
    using a manual hydraulic press, as opposed to an electric powered
    one, just release enough pressure to drop the platen so you can
    remove the cutter assembly out. Then when you go to cut your next
    disc, you won't have to do much cranking to apply pressure. Also, I
    put my cutter block on a piece of clean, smooth 1/4" thick Plexiglas
    so the disc drops to the Plexiglas instead of the press platen.  My
    discs don't get textured or scratched.
