Hi there,

    I'm new to the orchid forums and i just wanted to begin by thanking
    the creators and also the members for this wonderful community. I'm
    a beggining jeweler and i'm just attempting to begin casting. 

    Right now i' just installed my casting machine on a 250 concrete
    base set in wood. When put the flask into the cradle, melt the
    charge and trip the spring the silver always shoots out of the
    either the sides of the casting crucible or the actual flask pops up
    out of place and the silver shoots through the bottom of the
    crucible. 

    First off the area the casting machine is bolted into is level and
    very stable it does not move at all. Its set into a 250 pound
    concrete base and with the pot its in it weighs close to 300 easily.
    The casting machine is one i bought from santa fe jewelers (basic
    buffalo dental casting machine). 

    When the actual silver does go in it forms incomplete castings.
    (some of it shoots off the rest actualy goes in when i tie flask
    down with binding wire). 

    I can't figure out what the problem is. I'm doing everything by the
    book: 2.5 turns, sprues are the correct size, silver is molten to
    where it begins to swirl...etc. I honestly don't have a clue why
    this is happening and i'm losing a lot of silver through this
    process. 

    Any help would be appreciated:) 

thanks
