Sham If you add a motor to a hand grinder it is a good idea to have some way of holding the motor & grinder body in a clamp, rather than hold the grinder body by hand…in short, an electric grinder would probably work out cheaper.

    A few people have done similar, making a holder to hold the grinder is the trivial part (I intend it to be a ‘portable’ counter top grinder). The tricky part is specifying a motor with enough torque that is very cheap too, as well as a solid coupling.

    Save up and buy a Made by Knock can’t go wrong. My Feld 2 is brilliant I love it.

      They often come up on eBay too. Or check Bella barista outlet for something

        A cordless drill works as well as anything as a cheap way to motorise a hand grinder.

          Jony I did see that grinder, but the K4/K6 seems better value. But I’ll keep a look on ebay if they do pop up for a good price used.

          Cuprajake Too far out of my budget! £100 is the max I’ll go currently sadly.

          Dusk Yes but there’s no fun in that! I think it’ll be fun to design and make something, and if works well enough I could sell a few to cover material costs 😉

          Pompeyexile It’s a great value and good little grinder. It will grind for espresso, but it’s quite slow to do so…that said, you can press the button and walk away, it will auto stop when done.

            Too long time for espresso. I guess it’s alright for filter but for espresso? Probably better to hand grind. They had to pick a weak motor because it runs on a battery I guess.

            Just letting anyone who’s interested that the Kingrinder K4 is back in stock at £88 on their official Amazon store. Looking forward to trying it soon 🙂
