Warning: I was pouring a simple aluminum bracket wrong for a decade
For years at our foundry in Dayton, I'd just dump the metal straight into the mold from the crucible. About six months ago, a new guy from a big shop in Detroit watched me and said, 'You're pouring too fast, you're trapping air.' He showed me to tilt the crucible slowly and pour along the side of the sprue, not the center. I tried it on the next run of 50 parts, and the scrap rate from porosity dropped by half. Has anyone else had a basic pouring technique that they had to unlearn?

Yeah, the beer glass thing is real. I used to just blast the tap open and get a glass half foam. My uncle, who's had the same local bar stool for 40 years, finally looked at me and said 'kid, you're pouring a protest, not a pint.' He made me watch him do it slow, with the glass at a 45. Total game changer, no more waiting for it to settle. Funny how the simplest moves are the ones you never get shown.

Guess you can teach an old dog new tricks. Just takes a decade and a new guy.

Actually that trick with the beer glass works, it's just about the angle. You tilt the glass and pour down the side first to avoid too much foam. My buddy who tends bar showed me that after I made a mess at his place last summer.

Honestly, that's like me learning you shouldn't just slam a beer glass down on the bar to settle the head. Some basics you just miss.
