Guess Friday is now mandatory pet tax day.

Ever try to chill a casting too fast and get a network of cracks that would make a map look simple? I once got impatient and quenched a thin part, now it sits on my bench as a reminder of what not to do. Your sand trick is clever, just letting everything settle down slowly. I've heard about adding a riser to feed the thin spot, but that sounds like more work than I'm willing to mess up. Sometimes the answer is just to not be in such a hurry, which is advice I clearly need myself.
