Appreciation post: That one stubborn core print on the big gearbox job
Spent 14 hours over two days chasing a 0.005 inch mismatch because the damn core kept shifting in the drag. Anyone have a foolproof trick for locking down a tall, skinny core print in green sand?

Try a steel rod through the core print into the drag.

That steel rod trick is solid. I had a core try to float last year and a couple rods through the print into the drag was the fix. It held everything down just right.
