That time a cracked core box nearly shut us down for a week
Honestly, last Tuesday our main core box for a big engine block order split right down the seam during a pour, and we had to stop everything for like six hours while we scrambled to fix it. Ngl, we ended up jury-rigging a steel band clamp around it just to finish the shift, but it was a total mess. What's the fastest way you guys have patched up a core box in a pinch?

Honestly, that steel band clamp sounds like a solid fix to me, not a mess at all.

Yeah, it's a solid fix like @eva_thompson said, but you gotta crank it down really tight or it'll weep again later. I've used them on old pipe threads in a pinch and they hold if you do it right. Just don't expect it to last forever like a proper solder joint would.

Wait, you guys ran a jury-rigged core box for a whole shift? That's wild. I would have been sweating bullets the entire time, just waiting for it to blow again and spray hot sand everywhere. We had a small hairline crack once and we shut down for inspection after two pours, no way I'd trust a full split.
