My first foreman told me to always run a facing pass before any finish cut, no matter what
This was back in the late 90s at a job shop in Dayton. He said it would guarantee a perfect surface, but it added about 15 minutes to every setup. I followed that rule for years until a new guy, fresh from tech school, showed me his setup for a simple aluminum bracket. He skipped the facing pass, used a fresh end mill, and got a mirror finish in half the time. It made me realize some old rules can hold you back. Anyone else have an old piece of advice they finally dropped?
My old boss at a gear shop insisted on a three-step deburring process with specific files. It took forever. I watched a younger guy use a powered deburring tool on the same parts and it was cleaner and five times faster. That was the day I stopped treating his word as gospel. Sometimes the new way is just better.
What specific files did he make you use? That old three-step method sounds like it came from a time before good power tools existed. Stubborn tradition just kills efficiency.
