My lead hand argued that a 0.0005 inch tolerance on a bearing seat is just for show

He said the assembly guys will just tap it in anyway, so why waste the time? I read a case study from a motor shop in Dayton where that exact slop caused a whole batch of units to fail early. What's the real cost of chasing those last tenths on a non-critical fit?

My old shop learned that lesson the hard way too.

Yeah, @taylerm89, it's a tough lesson. A lot of places just don't get how much a bad process costs them until it's too late. They think they're saving time or money by cutting corners, but then they waste way more fixing the mistakes. It hurts quality and makes the whole team frustrated. Once you see the real price tag on sloppy work, you never go back.
