Had a core shift scare on a big gearbox casting in Erie last month.
The chaplet on the main bearing seat gave way during the pour, so I had to stop the ladle, signal the crane, and we used a steel rod to manually brace the core until the metal set enough to hold it, which saved a two-ton casting from being scrap.

How long did you have to hold that steel rod in place?

Manually bracing with a rod is a wild move under all that heat. What kind of setup did you have for the rod, like was it just a guy in a suit holding it against the core, or was there some way to lock it in place temporarily?
