We had a core shift on a 500 lb ductile iron casting last Thursday.

The cope half moved maybe a quarter inch in the flask before we poured. What's the best way to check flask alignment before you start, besides just eyeballing it?

Ever try a straight edge across the flask pins?

A quarter inch shift on 500 pounds is terrifying.
