Thinking more on Keelan’s damaged delivery and elevator transfer cam. Bill Spurling pointed out this repair that had been made on his Model 14
I know brazing cast iron can be tricky business, and it seems to be difficult to find folks who are willing to do it these days, but it can be done and in this case it is a clean effective repair. This solution seems to be a heck of a lot simpler than pulling the main cams and shaft apart. Still, the mystery is: how did this thing break? As far as I can see, this part of the cam is used to assist in retracting the ejector lever after the slug is ejected, but it seems that the mold cam lever does most of this work. I can't really imagine what would have caused this much force to crack the cam.
