    That is not a bad idea, but the fumes would be too much when it got hot.

    They use a ceramic adhesive at the Metal Museum, but I just recently noticed it in castirongypy's video, and so I don't have any on hand.

    I went out yesterday to buy more of the Rutan's furnace cement that I have been using to seal the mold edges, and the hardware store that I had been buying it from no longer carried it.
    The world is getting scary. The checked with every stocker in the store, and not only did they not have a clue as to what furnace cement was, they did not seem to know what a furnace was either. YIKES ! We are really peaking in the world with our ignorance of anything technical, at least in this city anyway. Scary.

    I went to a larger version of the same store, and was sure that they would not only have furnace cement, but would surely know what a furnace was.
    Nope, nadda, SOL, they did not have the slightest clue, and every one of the workers had this blank vacuous look on their face.
    This country needs to regain some of its technical skills if it will survive the next generation.
    And note, being active on FB is not a technical skill.

    I will use the thinner version of the Plastic A that I bought, and I think it is thin enough to work as a sealant.
    I don't really want to waste Plastic A, but until I can find out exactly what they use at the Metal Museum, and acquire some of it, I will have to make do with what I have.

    Once the cement dries today, I am ready for a melt, so it is just a matter of getting my stuff together and doing it.

    Mold halves cemented.
    Breaking up scrap iron and measuring out ferrosilicon.

    Two layers of cardboard under the crucible.
    Crucible charged.
    Snap flasks removed.

    Need to let the cement dry a bit.

    Today may be the day if all goes well.
    Making final preparations for iron pour.

    Pat this is just the state of the world today. The ability for the average millennial to use simple hand tools is gone. Blame it on what you want, but I
    firmly believe when there isn't a proper DAD living in the household, sons suffer. My wife's breast cancer screwed. I'd like to think we
    would have raised some pretty amazing stand on your own two feet kinda kids.

    done.
    seems like the bearing cap filled on the slow side, which may or may not be good.
