Can't say I agree. I find his verbal frills kind of annoying. And he's not quite the expert he pretends to be.
* The lack of a key between the small pinion gear and motor shaft isn't a 'cost saving', it's a feature. Allowing over-torque slip prevents damage to the gear in the event of the grinder disk coming to an instant halt due to jamming in a cut.
* The motor rear end bearing having that rubber cup - he makes out it's a silly idea, but it has very good reasons for being there. One being noise damping. Two, it prevents the bearing outer part spinning in the plastic case if the bearing gets a bit stiff due to dust. This is essential because once the bearing outer starts spinning in the plastic, it very quickly melts the plastic and irreparably ruins the machine. I've seen this happen.
* The main gear - he goes on about how the surface is slightly rough under a microscope, and talks about how some machining and grit blasting process produced that finish. He does not seem to understand that surface texture is due to the gear being made by mold pressing and heat-sintering a metal powder. It was never 'machined'.
