That's not manufacturer fault. That's part of customer due diligence when decides to buy an item from an overseas manufacturer. It does not apply on Bplus only. In my case I'm well prepared to face it, just because I can duplicate any part at the toolshop, so who cares. I'm used to restore high end vintage turntable arms down to the needle microbearings, I'm not scared by a hand operated coffee grinder

There is not aluminum rubbing against steel here.
Mixed aluminum-steel assemblies is an engineering problem solved one century ago, more or less. And this is not an aircraft engine having parts working with 800 °C differentials just 20 mm away each other.

I think you read only the even lines of my thread.
The burrs stop rubbing each other at an adjustment that is light years away from espresso range, and doing some approximate reverse math the radial runout should fall around 0.08 mm, give or take.
Searching thru the forums I've spotted people complaining abut burrs rubbing in the working range on other hand grinders, that is an order of magnitude worse than the Apollo does. Given the price tag, to me is enough to qualify the Apollo as a fine instrument. I'm not dumb enough to try to compare this performance to a HG1 or a Stance.
Has your M47 0.00002 mm of radial runout? Ok, good for you, I'll sleep well anyway.
