The air rammer has its place for sure, but you're right that it's not great for delicate work. Cold shuts and misruns usually come from not getting uniform sand density around the cores, and a mallet lets you feel exactly where it's packing tight or staying loose. Those pneumatic tools just hammer everything the same way, so tight spots get over-packed and you get voids in others. It's not really about losing the touch, it's that the tool doesn't have the control to match the pattern's needs. For complex cores on my shop's old jobbing work, I'll reach for the hardwood mallet every time.

2002 me would have called the Ask Jeeves advice brilliant after finding a driver fix that way.

Boil-overs wrecking the setup" - yeah, life's just like that, one little spill and the whole plan's toast.

Did the fountain think it was auditioning for a role in a disaster movie? I guess the mall decided to give you an indoor water park experience without the ticket price. Sounds like that bench was the real hero of the day, sacrifice and all.

And that's basically how it goes with everything now. People think they're smarter than the engineers who designed the thing. I noticed this pattern with phone chargers too. Everyone buys cheap cables off Amazon and then wonders why their phone charges slow or stops working after a month. Same with car parts, same with kitchen appliances, same with pretty much anything that has moving parts. The original stuff was tested and approved for a reason. Nobody wants to pay the extra upfront cost but they'll gladly waste money replacing cheap garbage every few months.
