A lead mechanic told me my torque wrench technique was off by a mile

I was doing a wheel change on a Cessna 172 last month, and the lead mechanic watched me for a minute. He said, 'You're pulling that wrench like you're starting a lawnmower. You need a smooth, steady pull to the click, or your readings are junk.' I realized I was jerking it at the end. I switched to his method, and my torque values are way more consistent now. It's a small thing, but it matters for safety. Anyone else get called out on a basic skill they thought they had down?

The lead mechanic called out the jerk at the end? That is wild because I used to do the exact same thing on a torque wrench without even realizing it. @hugo50 it's funny how muscle memory can be so wrong until someone points out that tiny break in your rhythm. I bet three hours of wedging clay is rough but probably fixes bad habits faster than anything.

My old guitar teacher used to say the same thing about my strumming hand. I was hitting the strings too hard and choppy, and he made me practice slow, even motions for a week. It's wild how many skills, from tightening bolts to painting a wall, rely on that same smooth, controlled pressure instead of force. You see it everywhere once you start looking.

My buddy Jake had a pottery teacher who made him wedge clay for three hours straight. She kept saying "it's not muscle, it's flow" until his wrists got it. Totally what you're saying, @felix_bailey45, that same idea.
