Posted Mon Jun 10, 2013, 6:33am Subject: hario slim problems with light roast
I recently purchased a Hario slim. It seems to grind darker roasts like Full City+ okay, and I'm able to do a smooth continuous cranking. But when I use it on lighter and medium roasts, the hario starts and stops while cranking, more force is required, and the resulting grind is very coarse. Is this usual? Will it damage the burrs? I can't click too fine or it really gets bad, so I've been leaving things coarse. I did break a tiny bit off the round base of the crank, but I don't think that's causing this. (Or is it?)

Light roast are always harder to grind, you'll even see motorized grinders sound more bogged down vs darker (along with requiring a finer grind). The Hario Slim is a pretty small burr set so it will be harder grinding vs medium/darker beans.

Harder to crank, definately. Even my LIDO "catches" sometimes on light roasts. It helps keep the forearms toned.
The ceramic burr floats in that grinder of yours so it's possible that harder beans can push through resulting in a larger grind for a given setting. I have a chip in the ceramic burr of one of my hand grinders. I'm not sure how it happened but I'd be surprised if coffee beans caused it. My guess is something else, maybe a piece of sand, got in there by accident.
