You reminded me that I have a Hario Skerton sitting in the cabinet gathering dust. I added a minor mod to improve the consistency of coarse grinds for my French press, and I replaced the handle with a nut so that I could grind with a cordless drill.I accidentally stumbled onto this thread and now I'm looking at my poor Hario grinder like this:
The Niche looks killer and James Hoffman's YouTube channel is amazing (and a massive rabbit hole)!
Don't judge - it worked for me for a long time until I got my current grinder.
Anyway, maybe I'll play around with it a bit tomorrow and see if I can get a passable fine grind out of it. My Rocky doesn't get here until Saturday, so it can't hurt to play around. Worst case, I waste a little time and a few dozen grams of coffee beans.
