Removing The Pattern

To remove the pattern halves, a little gentle tapping is required. A couple of screws are screwed into the pin locations and the part lifts out.

Cope Screws

When you remove the pattern sometimes you knock some of the sand loose from the mold. Most of the time you can repair it in the mold. If the defect can’t be repaired, but it in a non-critical place you leave it and grind/machine the extra metal off afterward. When the defect is too large the mold is scraped and you start again. Due to the fact so much time goes into making a mold you do your best to repair them.
