Seriously though. I have a difficult enough time getting my Pharos started on some single origins. I can't imagine the amount of gearing required for 98mm flat burrs to be hand cranked.
It's not the first time someone came up with this idea. Conical burrs are well suited for handgrinders but flat burrs aren't. There's no arguing with the laws of physics. Setting a minimum requirement of 5 years use of steroids and a minimum of benchpressing 300Lbs to be able to operate such a handgrinder won't be a very good selling point
Humans just aren't made to do such tasks. The minimum rpm will never be met for these types of grinders and using gears will only make the problem worse as you have to make even more rpm's on the flywheel. Humans just aren't capable of doing that so it's not my attitude that's the problem here
