I have been making Coffee Mills for the last few years, but my supplier of the mill gave up so I had to come up with a new mouse trap. I found a crusher/grinder from Europe that produced a very nice fine grind but it was made for salt and it had a shaft. I had to come up with a way of using it in the coffee mill.
As you can see, I had to make a bean hopper as well so I made the lid of the hopper into a drive for the crusher, but my first attempt using a knob didn’t make for easy grinding, not enough leverage. So my prototype #2 did the trick.
It’s all made of Black Ash from Manitoba and finished with Woodturners Jelly….
