Broke my favorite workbench clamp trying to rush a glue-up

I was clamping a big butcher block top for a kitchen island last Tuesday and cracked the cast iron jaw on my quick-release clamp when I overtightened it. Took me 2 hours to rig up a replacement with a threaded rod and some scrap plywood that actually works better for deep reaches now. Anybody else had a tool fail teach you a simpler way to do things?

Huh. I mean I've definitely broken clamps before but I wouldn't say it taught me a better way. Sounds like you just jury-rigged a workaround that happened to work for one specific job. Once you need to clamp anything with a curved edge or actual even pressure across a wide board that threaded rod setup is gonna rack on you. Cast iron breaks because you overtorqued it, but a proper clamp still does the job better in most situations.

Wait, you actually broke a cast iron clamp by overtightening it? That's kind of impressive in a bad way, most folks just snap the handle off before ruining the whole body. I thought those things could take a serious beating, guess you found the limit for sure.
