Upload photos of the power supply and the motor,please!!

The wiper motor is a standard w124 mercedes benz wiper motor, you can see it in the video I posted earlier. I got this power supply:

Good news: 120rpm without loud, and slightly slower when under load. I get ~17g beans ground now in 30s with my 83mm TiN burrs (mine was the first unit with the coated burrs).

Bad news: the power supply has a fan that is very loud. And the motor is much louder than at 12V, too. Both of these combined are about same or louder than the bean grinding noise.

I'm not sure now I might return the power supply since I really dislike fan noise (it's a quirk of mine) and just deal with the 60rpm, or, sell and get something pre-motorized. Hmmm.

bikeminded, is this setup still working for you? any changes you would make?

Yes, it's working well. It's gotten daily use since I motorized and haven't needed to do anything to it. I don't think I would change anything. (Maybe had thoughts of making a new motor cover with a curved back, but just for looks.)

Going to motorized my hg1. Going with Bikeminded's setup. Thanks for sharing your build and where to order parts, very nice of you! Going to prototype the bracket out of plywood. Mymenhir's style of bracket but with plywood. Wish me luck!

Good luck with the build

Mymenhir's style of bracket sure is nice and that machining of the aluminum is first rate. The LoveJoy couplings is also very nice.
