    Yes, there are many types of pining or stitching.

    On a cast iron joint you drill through the crack, thread it the plug it with an appropriate screw.

    Glue it up and clean to your needs.

    The idea is the screw threads in the broken hole will actually keep the part from pulling apart. And the plugs are tiny. JR

    I have had luck with repairs of that sort by drilling holes and using cap screws. A couple of SHCSs would probably hold it stronger than the original CI. Come in from the outside edge. Drill with the correct size tap drill with the two pieces clamped together. Enlarge the leg holes for clearance. And if you counterbore for their heads a bit of putty would hide them completely if you paint over it. Go deep for a lot of threads in engagement for extra strength. That would probably be the neatest repair.

    I don't think that JB Weld would hold it.

    Notice how there is a cross piece that goes across the break before they stitch it lengthwise with the break with the threaded pins -- it'll hold just fine. Better than the original casting, in fact.
