Just realized I wasted a full day on a bad torque wrench calibration

I was doing a 100-hour inspection on a Cessna 172 last week and spent eight hours chasing a phantom vibration. Turns out my old click-type torque wrench from Harbor Freight was reading 15 foot-pounds low, so every cylinder base nut I torqued was under-spec. Had to redo the entire job. Anyone have a go-to shop in the Dallas area for reliable tool calibration, or should I just bite the bullet on a new wrench?

Oof, Harbor Freight strikes again lol. I'd just get a new one, not worth the risk.

Yeah Harbor Freight can be hit or miss. I had a similar tool start acting up and just took it apart to clean the contacts. It's been fine for over a year now. Sometimes a simple fix is all it needs.
