    During the virus period, I can't go out, it's time to separate the broken tank by blow torch.
    This is my first time soldering a stove, please forgive me for bad soldering.
    And forget to take pictures in the previous step.

    Nice that you attempted this and finished it. Don't think I would have.

    Very well done. I think the patch repair is the only truly viable fix for a stress cracked tank. After staring at the one picture for several minutes I finally realized you used bobby pins (hair pins) to clamp the patch in place for soldering, how clever. I need to throw a few in the tool box.

    In order to separate the tank, I bought three blowtorches in 2020. 5 GBP

    I learned a lot from this website
    Thank you everyone!
    I made a cup of coffee to celebrate.
