    replied to Welding Black Iron into tanks
    I hit submit too fast.
    Lots of ships and buildings were built from iron until somewhere around (?) 1920's. That is a huge guess.

    Wrought iron has a very low carbon content as compared to mild steel which can have up to .30%. Iron also has a mixture of slag and silica (glass) in...

    replied to Welding Black Iron into tanks
    Black Iron is a catch all name for mild steel. The black iron title is still used on some structural blue prints, although it is becoming rare.

    replied to Headboard
    It ain't as fancy as yours. This one is made of mild steel. The spider is a former trailer hitch ball. It's attached by a ΒΌ" diameter round rod that allows the spider to *crawl* across the webbing. Actually, it sorta swings in an arc from the pivot point at the top of the gate. I've got plans...
