POOR MAN'S HINGE REPAIR

Treblig said
Great Macgyver work!! I probably would have tack welded (wire feed) the splined end (head of pin) to the hinge since it probably won't be replaced for another 45 years. Don't want the pin to spin???

Now that the spines are hardened, they bight into the hinge boss pretty good. I contemplated tacking them as well but decided to go this route.
