Had to choose between two long boxes at a garage sale in Ohio...

I was at this garage sale last Saturday and the guy had two long boxes of comics... one was full of 90s Image stuff for $40 and the other was a mix of early 2000s Marvel for $60. I went with the Image box because it was cheaper but now I'm kicking myself - all those Uncanny X-Men issues I passed on are probably worth triple what he wanted. Anyone else ever pick the wrong box and regret it?

My grandma told me to always save the water from boiling potatoes. I thought it was just an old habit, but I've been using it to make soup bases for a year now.

Just wasted $85 on a 'universal' O2 sensor socket that stripped the sensor on a '17 F-150. It was the wrong style entirely.

Had a core shift on a big gear blank at the old Hamilton plant last Thursday

We were pouring a 400 pound steel gear and the core moved about an inch and a half just before the metal set. My foreman, Jerry, told me to hit the riser with an oxygen lance to keep it open while he got a backup ladle ready. We ended up adding another 50 pounds of metal to feed the cavity and it actually saved the casting. Has anyone else had to do an emergency feed like that on a big job?

Appreciation post: my uncle's 'just tap it with a hammer' fix for a stuck injector on my Duramax actually worked after three tries.

He said to use a brass punch and a 2-pound mallet, and after I finally got the angle right, that stubborn injector popped free like nothing.

I finally understood why my sand molds kept crumbling

I was casting a small decorative piece at home last month. Every time I packed the sand mold, it would crumble when I removed the pattern. I tried adding more binder, but that made it too hard. Then I recalled a chat with a veteran caster about sand moisture. I tested different water amounts until the sand felt just right. The next mold held together perfectly, and my casting came out smooth. It's amazing how such a small detail can fix a big problem. Hope this tip helps someone else with their home projects.
