    Default Repairing busted off cooling fins on cylinder jugs & heads

    Any of you guys ever attempt to weld up broken off cast iron fins on your
    old iron? I have an OEM pan cylinder jug that looks like crap since the broken off
    fin is in a real obvious spot & really stands out.
    I would really like to have this repaired, But I have heard that welding cast iron
    is extremely difficult or impossible. Also the broken fin piece is gone which sucks
    even more.

    I have seen aluminum heads that had fin repair & some of them looked excellent.
    But what about cast iron...... ?

    braze it up and re-shape.
    i have also seen cardboard taped to the bottom of the fin and then j-b weld piled on to the right thickness.after it was shaped and dressed and painted black you couldn't tell it.
