I've been over-tightening bottom bracket cups for years without knowing it.
A customer brought in a vintage Trek with a creaking threaded bottom bracket. I put my usual force on the fixed cup, but the creak came back after a week. He brought it back and said, 'My old shop teacher always said to stop when the wrench feels solid, not when your arm hurts.' I tried his way, just snugging it up firm, and the noise is gone for good now. How do you all judge the right torque on parts without a gauge?

Honestly, @theas94 has a point about the beam wrench, but how do you know when the shell is faced well enough to even trust a torque reading?

Seriously, people overthink this stuff.

That shop teacher advice is way too vague for something critical. "Feels solid" means totally different things to different people. For a threaded bottom bracket, you really need to chase and face the shell first, then proper torque is key. A cheap beam-type torque wrench for the big stuff takes the guesswork out. Why risk crushing a frame or having it come loose?
