    Default cutting large radius in 1/2" plate

    Hi
    I'm trying to cut a 58" radius approx. 84" long by 1" wide from 1/2" plate. (drawing attached)
    Hyperther 1250 machine torch
    80 amp
    39 IPM
    down draft table, no water table

    When I remove it from the plate it springs open about a 1/2". I tried adding tabs to each end and one in the middle, letting it completely cool and then removing it and same thing as soon as i cut the tabs it sprung open. Just wondering if anyone has any suggestions for cutting this.
    Thanks for your time.
    Chris
