There are people repairing pot metal...look in Hemmings Motor News....or use and epoxy to fix it from the back....You can use a coat hanger in the epoxy from the broken piece to another piece to strengthen it. Or any other small piece of metal to bridge the repair...get the idea???
you could braze it couldn't you?...
might need to find some silver rod to do it with or your going to have color issues...... unless you could get it rechromed. but i think you could braze it to perfection.
Thax for all the responses but I think I might have to find a new one because this part is going to be in a spot where it is going to take abuse and I don't think a epoxy will hold and brazing won't stick. I tried it on a scrap piece and it just melted the pot metal.
