Like a few others here im a tinkerer at heart and an impassioned "maker" at heart. I recently got into the coffee game by modifying a gaggia classic pro to an gaggiuino, after deciding on the machine i set my sights on a grinder. Which now led my to this project after much searching and comparing.

Ive chosen to use a 400w servo motor as the base of this grinder and the lebrew sweet burrs. The main grind chamber and burr holders are going to be aluminium that im going to turn on a lathe. Things like the wipers and threads are going to be 3d printed out of ASA or similar atleast to start with as the lathe im currently using has a broken power feed.

Whats not in the cad is the base. Its gonna be a leaning version at around 35 degrees. Im probably gonna build the base out of some kind of wood, maybe plywood just to get something quick together to test. 

Im in the process of fabricating some of the parts so its very much an ongoing project. If i by the end get an functioning grinder im going to make it open source write BOM etc.

For now if anyone wants to have a look at the cad its over on onshape here
