Hi Guys,
I'm a first-time poster, but long time lurker. A big thanks to the forum, it's been a wealth of information over the years. It was this forum that got me interested in a 'proper' espresso machine years ago - resulting in the purchase of a Rancilio Audrey and Rocky for home, then a second Audrey and Rocky for work, and finally a third Audrey, just in case one of the other two broke down.
Anyway, I'm making my own coffee grinder using Mazzer Major 83mm flat burrs, and I'm about to machine a tangential discharge port in the grinder body, and thought I should double check the direction of rotation of the burrs before I make a mistake!
If you are looking down on the rotating burr, (the one attached to the motor shaft), I assume that the rotation is clockwise?
Cheers, Steve.

The spindle design also includes an adjustable nut to preload the bearings to remove any axial and radial play. (A common practice on metal lathe spindles.)
