    Since lead melts at 612 degrees F and cardboard burns at about 450F, I'd be reluctant to trust a cardboard tube as a mold for lead, even if it was lined with foil. It would be safer to heat up some pieces of appropriate-sized steel pipe to drive off any residual water, plant them in a bucket of dry sand, and fill them with the lead. You can drill them for wire handles after it cools. Avoid touching the lead or breathing the fumes as it melts.

    Not what I have found. Even the EXPERTS on the video said it would work. LOL. To each his own, but you make some good points.
