I’m not the first and will not be the last to modify the Hario Skerton grinder. The Hario Skerton is a terrific manual, ceramic burr grinder with a following by coffee aficionados.
Unfortunately it takes a good deal of effort to grind enough coffee for 5 Aeropress scoops (yes, I plan ahead and grind more coffee than I need). To turn this fantastic, but slow grinder into a fast electric grinder you’ll need a few items.
This is a Japanese grinder and all the hardware is metric. You’ll find metric hardware at an automotive parts supplier. Don’t go to a hardware store like I did.
10 mm acorn nut
10 mm hexagonal ratchet socket
2x 5 mm washers
A drill bit ratchet adapter
A drill with variable speed
You’ll need to remove the screw and handle from the grinder. This is as simple as removing the thumb screw and pulling off the handle.
|Two washers and an acorn nut|
Next stack and place the two washers the drive shaft. Then place and tighten the acorn nut onto the drive shaft.
|They spinnin’ !!|
Finally use your socket and drill bit adapter to spin the acorn nut in place of manual labor.
The materials, excluding the drill (I had one already) were under $10 CA .
