Holy crap. Not exactly on subject, but my HG-One showed up about 8 tonight, ran about a pound of rice through it, then pulled a couple shots. Holy crap. What a difference compared to what the Rocky delivered. Heckofalot easier to turn with beans compared to rice, but a motor will be added. Happy. Carry on.

Tom, the HG-One certainly is an upgrade from a Rocky, more accurately a quantum leap! It is an excellent grinder and I would not have motorized it if my arthritis was not getting to a point of causing me grief while making coffee.

I put the second version of a base plate extension on it and coated the bottom in cork. It slides on the counter if necessary and is now very stable since the base plate extends toward the rear of the grinder and changes the fulcrum point significantly. It now takes real effort to rock it to the rear.



It slides under the cabinet uppers.




Complete and ready for years of use!

I'm so jealous but it's definitely a project I could not handle myself and would have to take somewhere. That would defeat the purpose of me wanting to build it myself.

I'm tempted to see what everyone else comes up with. I assume for stability reasons the motor has to be attached to the HG one body.

I have not seen a flexible shaft adaptation nor do I know if a flexible shaft would take the required torque.

Maybe some other engineering types might chime in and let me know if such an option might be possible.

Mounting the motor on the HG-One was for ease of doing it rather than for stability. Stability is not an issue at all unless you get the motor to far to the rear and it rocks the grinder back onto the motor. The first base plate was just the footprint of the HG-One and it was ALMOST to small for the large motor. I extended it to the rear yesterday and not it is perfect.

That's a beautiful setup Stephen. Someday my little Lelit wants to grow up to be one of those.

I like the cork base on the new baseplate as well.

FWIW...Here's something I was researching as a way to get a poor man's anodize on Al parts. I have not tried yet on other projects, but planning on getting some to experiment with. My impressions are the Al must be *very* clean in order to work properly. (I'm getting way ahead of myself though.)

It tends to wipe off relatively easy.

These finishes stick, either one.

Cool! Thanks for the Link and the compliment I debated whether to anodize or polish or just leave it satin. Still debating....

Thanks for these! I also have an anodizer about 8 miles away which I have used in the past but I thought that he might take to long to do the work. Still debating about sating Alu.

I just published the finished grinder project with 2 small exceptions.

A possible anodizing of the raw aluminum. Also the installation of a Power On Lamp with a Forward/Reverse w/center lockout Neutral(off) and Reverse Temporary ON. Pretty tricky switch to find but evil bay provided

Nice writeup Stephen. Thank you!

I've been down the coffee grinder motor project rabbit hole this week and got my version operational. Hope to get some pixs videos up before the weekend is out. I like it.
